Introduction: Wheat is one of the major food crops in our province. The annual planting area is about 30 million mu. The 29 counties (cities, districts) along the Huaihei-Huaibei area are the wheat industrial belts of the advantageous agricultural products delimited by the Ministry of Agriculture, and they are doing a good job in the construction of high-quality wheat industry belts, planting good quality wheat, and promoting the use of fine varieties and advanced wheat. The application of production technology is also an important measure to promote agricultural production increase, increase farmers' income, and increase the competitiveness of agricultural products. How to save production costs in agricultural production, increase input and output efficiency of agricultural production materials, and increase farmers' income are major issues. It involves biotechnology, engineering technology, information technology and so on. Here only a brief introduction to the cost-effectiveness of wheat production. I. Technical aspects of wheat production and cost-efficiency improvement projects In the process of wheat production, the technical content and technological content contained in the project will be continuously improved with social development and technological progress. At this stage, the main contents of the cost-saving and efficiency-increasing engineering of wheat production are: crop-saving, fertilizer-saving, pesticide-saving, water-saving, fuel-saving and labor-saving days. As well as the technical measures taken, the list is for reference. Technical contents Technical measures: Seed processing and processing (drying, cleaning, coating), fine-scale sowing fertilizer, soil testing, formula fertilization, chemical fertilizer deepening, straw pest control, pest control, pesticide selection, Safe and low-cost precision application of water-saving shallow dumping deep loosening, cultivating repression, low-pressure pipe irrigation, irrigation and fuel-saving performance testing, adjustment and maintenance, duplex operation, less ploughing and saving labor, machine seeding, machine harvesting, and machine transportation It can be seen that the mechanization of key technologies in wheat production is the main technical measure to increase efficiency. Second, the key to promote the production of wheat to increase the efficiency of mechanization technology 1, a small amount of sowing mechanization technology is the key to sowing, to grasp three elements: the choice of high-quality seeds, suitable sowing time, standardize the quality of sowing. Here, mainly briefly explain how to improve the sowing quality? How to meet agronomic requirements? Make full use of the natural conditions of soil, fertilizer, water, light, heat and gas to provide a good environment for the growth and development of crops, improve the relationship between individuals and groups, and scientifically realize the docking of seeds and soil. Rely on the carrier, rely on engineering technology - to take mechanized fine-mining seeding technology. Fine seeding is a very obvious cost-saving and efficiency-enhancing project in agriculture. It is labor-saving (1-2 workdays), provincial seed production (3-6kg/mu), and increased production (10% or more). The mechanized fine-mining seeding technique refers to the technique of mechanically seeding a certain number of seeds according to agricultural requirements (row spacing, spacing, depth, and sowing volume). The essence of the method is to reduce the sowing quantity, deal with the contradiction between the population and individual development, improve the light and nutrient conditions of the effective tillering in the plots with good soil, fertilizer, and water conditions, and achieve high spike-making rate, multiple spikes and grains. The grain is full so that high yield can be achieved. The constant machine sowing has been basically pushed out in the wheat producing areas of our province, but the development of fine-mined sowing is unbalanced. It is necessary to further increase the promotion of fine-mining sowing techniques and improve the quality of sowing. From different crops, different cornices and different natural conditions, different seeding techniques and different functions of the seed drill can be used. At present, there are several types of domestic planters: dedicated planters, precision planters, fertilizer planters, film planters, water planters, and stubble-free tillage planters. Wheat production in our province is affected by factors such as natural conditions and pre-crop crops. From seed quality to cultivation techniques, it must be adapted to local conditions and classified. The former crops are corn, soybeans, hawthorn, and cotton. The sowing process route is: planting seedlings with seedlings at the bottom; the sowing process for the former crops is rice: shallow rotary ploughing with base fertilizers and trenching with machine seeding machines. To improve the quality of wheat sowing, it is crucial to grasp the following points: First, pay attention to soil moisture, meet the drought to build a lake, and encounter stains to drain; second, improve the quality of cultivation, especially the fineness and flatness; The advanced and suitable seeder is selected to ensure reliable transmission, uniform seeding, and accurate seed input. Fourth is to strengthen the training of the seed driller, to be familiar with the use and adjustment of the seeder, not to reproduce or miss the broadcast, and to pay attention to the linearity of the seeding and Reliance on the line. 2. During the autumn season, the mechanized deep application of chemical fertilizers will vigorously promote fine seeding techniques. At the same time, it must also pay attention to the promotion of deep application of fertilizers. It is also an important part of improving the quality of autumn seeds. The root system is the main organ for sucking fertilizers in crops. This is a simple matter of deep chemical fertilizer application. Deep application of chemical fertilizers refers to the use of machinery and hand tools to apply chemical fertilizers according to the number of crop growth requirements and fertilizer location effects to a certain depth below the surface of the soil. According to the technical content of chemical fertilizer application, there are three main forms: 1 Deep application Base fertilizer; 2 deep seed fertilizer; 3 deep application fertilizer. Deep application of chemical fertilizers is a relatively mature technology for increasing production. If mechanized deep application of fertilizers combined with soil testing and formulating fertilization. It has better economic and social benefits for improving the utilization of chemical fertilizers, reducing production costs, increasing crop yields and reducing environmental pollution. According to research conducted by the Institute of Soil and Fertilizers of the Chinese Academy of Agricultural Sciences, ammonia ammonia and urea are applied deeper than the surface fertilizers, and the utilization rate of ammonia nitrogen is increased from 27% and 37% to 58% and 50% respectively. The deep application of phosphate fertilizer and potash fertilizer can also be reduced. Wind erosion, increase fertilizer efficiency. The general chemical fertilizers are deeply applied to the soil below 6-10 cm, and the amount of volatile loss of chemical fertilizers is significantly reduced. It is estimated that if the target of increasing fertilizer utilization by 10% can be achieved, the country can save 21 million tons of chemical fertilizers, equivalent to 70 fertilizers produced by chemical fertilizer plants with an annual output of 3 million tons. During the wheat planting period in our province, the plough-bottom fertilizing device can be installed on the tractor unit when arable land is used, or the compounding operation of the fertilizing seeder can be used. Where there is no condition, it is also a good idea to drop the furrow manually. Other crops should also actively promote fertilizer application technology. At present, the domestic solid and liquid manual fertilizer deep applicators for topdressing are evenly mature. Mengcheng, Guoyang, Xiaoxian, Feixi, and Fengtai all produce ploughshare fertilizers that can be used. Due to the different conditions of agricultural production in different parts of the country, the level of agricultural mechanization differs greatly. Therefore, we must promote local conditions and promote the use of local mechanization, semi-mechanization, hand tools, and other deep-improvement methods to gradually advance technological advances in chemical fertilizer application. 3. Phytosanitary plant protection mechanization technology In order to make full use of the effective role of pesticides and try to prevent possible harm, the application of chemical pesticides must reach three conditions: First, efficient, low toxicity, low residue pesticides; second, advanced and reliable The spraying equipment; the third is a safe and reasonable method of application. Phytosanitary plant protection machinery provides effective means for large-scale, high-efficiency and low-residue pest control. The pesticide-free plant protection mechanization technology applied in China's agricultural production is commonly known as spray, dusting, and ultra-low volume spray technology. 1 The spray dusting mechanization technology is the most widely used plant protection technology in China. It has a compact structure, long range, high atomization performance, high work efficiency, a wide range of adaptability, and agents for different media, such as oil, water, emulsion, powder Can be used for weeding, soil treatment, fertilization and sowing operations. It can be equipped with multiple injection parts, such as: high-capacity nozzles, mist nozzles, ultra-low-volume nozzles, dusting devices, spray particles Equipment, etc., to achieve a multi-purpose machine, reduce costs, comprehensive control purposes. The commonly used Models are backpack type, stretcher type, hanging type. 2 Ultra-low-volume spray mechanization technology What is ultra-low-volume spray has a variety of different arguments. For example, the U.S. Department of Agriculture made a provision for ultra-low capacity, that is, when using concentrated pesticides (without dilution of thick oil), the dilution should be less than 50% of the volume of the pesticide itself. In general, according to the unit system of our country, the application rate of more than 30 liters per mu is called regular spray, also called high-volume spray. The application of 0.3-30 liter per acre is called low volume spraying, and the application of 0.3 liter or less per acre is called ultra low volume spraying. From the point of view of the size and type of spray droplets, the use of droplets in ultra-low sprays is ideal for both aerosol (30-50 microns) and mist (50-100 microns). Droplet size classification, type and scope of application Droplet diameter (micrometer) Droplet size classification Range less than 5050-100105-200201-400 More than 400 aerosol droplets Fine droplets Medium droplets Thick droplets Ultra low volume spray Ultra-low-volume spray Low-volume spray High-volume spray (ie, conventional spray) The ultra-low-volume spray technology identified in China has the following characteristics: A. Fine mist flow, high concentration, good penetrability in crops, good penetration, long time Good control effect. B. Compared with the conventional spray, pesticides can be saved by 10%-30%, and the amount of sprayed liquid is small. As a result, the amount of drug lost to the ground is relatively reduced, and environmental pollution is reduced. C. With less water consumption, it is suitable for large areas such as aerial spray, arid areas and forest areas. Ultra-low-volume spray technology is a new technology for medicines that includes pharmaceuticals, medical devices, and use technologies. Ignoring one of these factors will affect the implementation of the technology. 4. Mechanization Technology for Direct Return of Crop Straw to Straw The technique of mechanization for straw crushing and returning to the field is to mechanically crush, chop, break hoe, deep plow, rotate tillage, and pressure the straw. The straw is directly buried in the soil or chopped Covering the surface of the technology. All countries in the world with developed agriculture attach great importance to the development of sustainable agriculture and pay attention to the scientific and rational structure of fertilization. The application of general fertilizers is controlled by about one-third of the total amount of fertilization, and straw returning and manure application account for two-thirds of the total. Most of the wheat and corn stalks in the United States, Canada and other countries must be returned to the field. In July, I visited the Ministry of Agriculture’s Agricultural Machinery Research Mission in the central part of the United Kingdom. Most of the straw covered the fields and the forage harvested and baled. In 1994, the amount of fertilizer used per hectare of farmland in the country reached 346.5 kg (81 kg/hm2 in developed countries, and the average world level was 91.5 kg/hm2), which has exceeded the world average of 2.8 times. This shows that China's fertilizer application is too large. Mechanized straw returning not only grabs crops, but also grabs accumulated temperature. It promptly solves a large amount of straw on-the-spot, avoids the problems of incineration and environmental pollution caused by farmland rot, and provides land for large-scale land use, increasing soil organic matter content and reserves. Water conservation, improvement of soil fertility, reduction of fertilizer use, saving of production costs, increase of crop yields, and establishment of high-yield and stable agriculture have created new ways. From 1994 to 1995, the experiment of returning wheat and corn straw to Suixi County in our province showed that the production of a certain amount of straw was significantly increased. The following is a comparison of soil physicochemical properties and grain yield with direct crushed 1500, 1000, 500 kg straw per acre compared with the control field. Returning soil volume (mu/kg) reduces soil density (%) and increases organic matter content (%) Increase nitrogen content (%) Increase available phosphorus content (%) Increase available potassium content (%) Increase food production (%) 150010005005.653.151.5513.7410.697.6315.1510.16.0627.4418.215.4218.9311.036.319.3112.375.9 Wheat and corn stalks Mechanized returning technology points, please watch the video VCD. 5, all-round deep loose technology Our province's northern Huaihei Huaibei wheat production areas, mostly sand and black soil, long-term use of small tractors and human and animal husbandry, coupled with unscientific use of chemical fertilizers, low organic fertilizer, under the comprehensive effect of nature As a result, the soil compaction and the tillage layer become shallow, and a hard plow bottom layer is gradually formed, which greatly weakens the flow of water and fertilizer between the tillage layer and the soil and soil layer, making the roots of the crop hard to stretch. During the rainy season, the rainwater from the bottom of the plough can not be infiltrated in time and accumulates in the soil and soil layer. It is easy to form surface runoff, and even a large amount of soil in the cultivating layer is washed away. In dry weather, the bottom of a hard, compact plow makes it difficult to move the bottom layer of water to the tillage layer. It is easy to cause "rainstorms, heavy rains, and no rain and drought." It has an adverse effect on agricultural production. In order to change this situation, we introduced the patent technology of China Agricultural University, “all-round deepening technology†on the basis of research, and conducted demonstration experiments in some counties along Huaihe and Huaibei in our province, and achieved the expected results, which was also confirmed by the Ministry of Agriculture. . The so-called deep looseness refers to soil tillage techniques that mechanically loosen soil layers without inverting the soil layers. There are two kinds of deep loose and partial deep loose pine deep, or called: all-round deep loose and deep loose. The all-encompassing deep-steam technology is a V-type deep loose shovel with international advanced level, which is supported by large and medium-sized tractors. It is forced to enter a certain depth of soil layer during operation, breaks the bottom layer of the plough, lifts the soil layer up, and has the effect of smashing the soil. At the same time, a mouse-drenched underdrain is formed at the bottom of the deep pine to improve the soil's water storage capacity. This technology, also known as the "soil reservoir," is an engineering technology measure that makes full use of natural rainfall, pesticide-saving irrigation, transformation of low-yield fields, and increase of crop yields. Depth of the depth is generally 30-40cm. It is best to use rotary tillage after deep-steamed site preparation. Generally, it is called shallow-deep-removal method. Moderate repression is required after sowing. The implementation of this technology is best combined with the transformation of local low-level fields, organized and unified. All-around deep-slow technology application note: First, the power should be matched with the work tools, generally require more than 50 horsepower tractor; second, deep looseness to maintain the suitable tightness of the soil in the plough layer, in order to create a reasonable plough layer structure , Grasp a reasonable depth, deep loose way and deep loose interval time; Third, leaky land or transform the block is not suitable for deep loose. 6. Water-saving irrigation mechanization technology In view of the limited growth in water demand and the increasing demand, agricultural water will inevitably be squeezed by industrial water and urban and rural residents' domestic water consumption. Water-saving agriculture has already been placed in an important position. In fact, China’s water crisis began in the 1980s. It is necessary to ensure industrial water use and urban domestic water consumption, but also to increase the effective irrigation area of ​​agriculture, the need to increase water consumption, which determines the sustainable development of China's agriculture must go to a water-efficient road, improve the utilization of water resources. Water-saving irrigation technology is a comprehensive technical measure taken to fully utilize water resources, increase water use efficiency and utilization efficiency, and achieve high yields and efficiency of crops. It is a synthesis of water-saving measures such as water resources, engineering, agriculture, and management. Technology System. The use of this technical system will increase the overall utilization of irrigation water resources and increase the yield per unit area of ​​crops in order to promote the sustainable development of agriculture. Water-saving engineering technology is the core content of the comprehensive technical system of water-saving irrigation, including sprinkler irrigation technology, micro-irrigation technology, channel seepage prevention technology, and low-pressure pipeline water delivery technology. In the wheat production area of ​​our province, there are two main methods for popularizing and applying water-saving irrigation mechanization technology. The first is the small-scale mobile water lifting hose water delivery irrigation technology; the second is the sprinkler irrigation technology. Due to the relatively slow development speed of sprinkler irrigation technology, the next step is to focus on the promotion of sprinkler irrigation technology. It not only saves water but also has a significant increase in production. Sprinkler irrigation is the process of spraying pressure water into a low altitude by mechanical equipment and evenly falling onto crops and ground surface like a raindrop after atomization. Commonly used irrigation machines include artificial pipe-type sprinkler (including semi-fixed pipe sprinkler system and light and small mobile type), roll-type sprinkler, hose reel automatic sprinkler, and double cantilever sprinkler. Among them, small mobile sprinkler units account for 80% of the total number of sprinklers. It has the characteristics of low investment, good maneuverability, multi-purpose, suitable for small households, etc. It has nearly 200,000 sets of possession in our province, but it is really used for sprinkler irrigation operations. Most of it is used to pour water, it saves time, and it is not installed. Pipes and sprinklers. At present, farmers should be trained to master scientific and reasonable methods of irrigation and irrigation, so that they understand that water-saving irrigation not only saves water resources, but also increases crop yields. Sprinkler irrigation is used for many purposes. In addition to widely used agriculture and forestry, environmental control, sewage treatment, and aeration of fish ponds are also used. Sprinkler irrigation is very adaptable and it can be used for almost any crop, soil, terrain, region, climatic conditions. 7, rice buckwheat shallow rotary cultivator drill technology in rice and wheat continuous cropping area, due to the harvest before the glutinous rice, to the soil preparation and bring great difficulties, not only time, large amount of seed, and low yield. In the late 1980s, agricultural machinery and agricultural science and technology personnel collaborated for many years to research and explore new cultivation techniques. Through hard work, a mechanization technique for planting rice buckwheat sowing with rotation and tillage as the core has been formed. It has the characteristics of labor saving, province breeding, and yield increase. The technology is a rotary tillage, drilling, smashing, sowing, soil covering, compaction and other multi-spot preparation and sowing wheat operations in the rice field. It integrates agricultural machinery and agronomic organics to form a mechanized comprehensive technology for wheat high yield in the rice- wheat-crop continuous cropping area. The following technical points must be mastered when it is popularized and applied: 1. Rotating tillage and seeding as the core and attaching importance to the weight of the work. Rotary tillage depth is generally 3-5cm, so that the soil block is finely chopped and the stubble is removed. The row spacing and seeding rate are adjusted, the row spacing is 20-23cm; the seeding rate depends on the seed characteristics, the basic seedling requirements and the soil fertility and other factors, and the sowing volume About 9kg control. 2, timely ditch, rule out the surface water and reduce the soil moisture content to prevent waterlogging. A dedicated trenching machine is generally used. The depth of the trench is 25-35cm and the interval is 3-4m. When the trench is opened, the soil of the trench is evenly covered on the surface of the sown wheat. 3, rational application of fertilizer. Combining the characteristics of the cultivation of shallow-rotating, sowing and sowing wheat, a reasonable fertilization plan was formulated to ensure the normal growth of wheat and increase the yield. According to the results of many years' experiments in Jiangsu Province, the fertilization plan for the medium-fertility plots was as follows: Balance fertilizer, increase application jointing panicle fertilizer. 60% is used as base fertilizer, 10% is used for balance fertilizer before winter and early spring, and 30% is used as jointing and panicle fertilizer. 4. Pay attention to chemical weeding: Before or after sowing, depending on the weeds, humidity, and temperature, select the appropriate chemical herbicide on the road in time. 8. The harvesting of rice and wheat combined harvesting mechanization technology is a production process in the agricultural production process that is seasonally strong, with many workers and labor intensity. Compared with artificial harvesting, rice-wheat mechanized harvesting can shorten the harvest period from 10-15 days to 7-10 days, so that high-yield foods can be returned to the warehouse in time, crops can be planted on the next crop, agricultural time can be ensured, and agricultural production can be increased. Mechanized combined harvesting can reduce losses and waste in the grain harvesting process. The total loss rate can be reduced to less than 5%. The total loss rate of artificial harvesting is as high as 12%-15%, and the loss can be reduced by about 8%. In addition, combining harvesting to increase labor productivity and reduce production costs is also obvious. In recent years, the government departments have attached great importance to the effective demonstration and promotion of the promotion agencies at all levels, especially the development of social services such as cross-regional machine harvesting, which has further promoted the combined mechanization of rice and wheat harvesting. In recent years, the province's rice-wheat combine harvesting machinery has developed rapidly, and it is predicted that the amount of the remaining rice will reach 30,000 units by the end of this year. From the mechanized harvesting process, it can be divided into sub-stage harvesting and joint harvesting. The combined harvester can be divided into two categories of full-feeding and semi-feeding, depending on whether the stems all enter the threshing device. The whole feed harvester is divided into: backpack type, wheeled self-propelled, tracked self-propelled, and traction semi-feeding harvesters are divided into: Self-propelled and Suspended. According to the format of the header used, it is divided into horizontal header and vertical header rice-wheat combine. Regardless of the form, the basic working principle is the same. The cutting, conveying, threshing, separating and cleaning of rice and wheat are completed once in the field. Select items to get clean grain. The main components except the power running device are mainly composed of three parts: the header, the thresher and the intermediate conveyor. However, the biological characteristics of rice and wheat are different, and the structure of the threshing device is different in the combine harvester. Wheat threshing uses the principle of rubbing, while rice uses the comb brush principle. Factors affecting combine harvester operations include: ground water content (wheat) and foot depth (rice), length and temperature of straw, field shape, and field transfer path. Performance evaluation of combine harvester performance indicators: First, the total loss rate (header loss, transmission loss, cleaning throwing loss) is generally less than 2%; Second, the cleaning rate should be greater than 98%; Third, the rate of grain damage is less than 3% . In addition, the height of stay can also be requested (according to farmers' requirements). Third, take advantage of the situation to further increase the efficiency of wheat production to increase the efficiency of mechanized technical content. 1. Policy pulling and income increase by farmers will be conducive to structural adjustment of agricultural machinery and equipment. This year's Central Document No. 1 and the Provincial No. 8 Document were promulgated, which greatly mobilized the enthusiasm of farmers for grain production. It has become a foregone conclusion that agricultural production increases and farmers increase their income. Coupled with the introduction of subsidy policies for peasants' purchases by the central government and the province, agricultural machinery has once again warmed up, new purchases have been made and machineries have been used, and many farmers have sold cars to buy agricultural machinery. Under the new circumstances, new changes have taken place in the development of agricultural machinery in our province. First, the growth of agricultural machinery changes from small to medium-sized; second, the transformation of farm machinery from large households to large farm machinery manufacturers, large planters, and service organizations; and third, the category of equipment is increasing the efficiency of agricultural production by replacing the simple equipment of human and animal husbandry. High-performance equipment changes. The "Law of the People's Republic of China on Promotion of Agricultural Mechanization" has been promulgated and implemented. It has used publicity and implementation opportunities, actively promoted the production of cost-effective technology for wheat production and further improved the quality in the guidance of purchase subsidy policies and the implementation of national high-quality food industry project construction project areas. The technological content of wheat production. 2. The unprecedented prosperity of China's agricultural machinery market has actively guided farmers to purchase advanced and applicable agricultural machinery. It can be seen from the National Agricultural Products and Products Fair and the China International Agricultural Machinery Exhibition held in Hefei “Anhui International Convention and Exhibition Center†for the second consecutive year that China’s agricultural machinery industry and agricultural machinery market have undergone great changes. Regardless of product quality, variety, performance, technical content, or quantity, it can basically meet China's agricultural production needs. The prosperity of China's agricultural machinery market is due to the reform and opening up, thanks to the policies of the party and the country. Chinese and foreign agricultural machinery companies have spotted potential markets in China. The agricultural machinery products and production technologies of developed countries have entered China one after another. It is a promotion and promotion of China's agricultural industry. In China's social modernization construction, the relationship between agriculture and national economic development has generally entered the transition period of industrial support for agriculture (since the founding of the country has always been the industry backfeeding industry). Minister of Finance Jin Renqing published an article in the Economic Times Rural Edition on March 1, 2004: “Solving the 'three rural issues' and increasing the income of peasants must have two changes in macro terms. First, rural areas should support cities and agriculture. Supporting the transformation of the industry into a city that feeds back into the countryside, and that industry backs up agriculture; second, the public finances should gradually shine into the countryside." Since the Third Plenary Session of the 16th CPC Central Committee, the Party Central Committee and the State Council have issued a series of direct, decisive, and powerful policies and measures to solve the “three rural issues†problem. First, there has been a turning point in grain production, and farmers’ income has increased in varying degrees. Only the development of agriculture, the increase of farmers' income, and the prosperity of the rural economy have led to the prosperity of the agricultural machinery market. Under the current excellent situation, all localities must guide farmers to purchase advanced and applicable agricultural machinery according to local conditions. Focus on the development of large and medium-sized tractors and supporting agricultural implements (cultivation, deep-separation, rotary tillage, straw return, fertilization sowing) in high-quality wheat production areas, high-performance harvesting machinery, water-saving irrigation machinery, low-volume spraying plant protection machinery, drying and processing mechanical. 3. Strengthen the construction of social service organizations, pay attention to the combination of agricultural machinery and agronomy, and increase the promotion and popularization rate of cost-saving and efficiency mechanization technology for wheat production. In view of China’s national conditions, scattered land management, low levels of rural labor force culture, and the fact that young and vigorous laborers are working outside are relatively common. To promote a new technology, it is difficult to achieve it by traditional means. One important measure at present is to support and guide the establishment of various forms of social service organizations at the grassroots level, especially at the administrative village and villagers' level. We must support them from all aspects and finally achieve "win-win" or "win-win." In the mechanized production of wheat, agricultural machinery and agronomy must be closely integrated to show the best technical results. For example, sowing: what variety? How many acres of sowing? What time is it broadcast? What kind of seeder do you use? Another example is the harvest: What is the best harvest period? What form of harvester is chosen? and many more. To give two examples: short straw wheat and rice cannot be harvested with a half-feed combine harvester. After the rain, the wheat ground is too wet to be harvested by a wheel combine harvester. In short, in the development of high-quality wheat production in our province, at all levels of government and agriculture, agro-machinery departments attach great importance to the situation, and promote the cost-saving efficiency of agricultural engineering technology, further enhance the level of mechanization of wheat production, and make new contributions to modern agriculture.
