White radish has a long history of planting in China. It is one of the main vegetables that people eat daily. After long-term development and cultivation, the cultivation technology of white radish has been greatly developed and improved.
1 Overview
White radish, also known as Laiwu, is a rhizome vegetable with typical "three-shaped" and "four-color" characteristics. The so-called "three-shaped" refers to the three traits of the white radish having a spherical shape, an oblong shape, and a conical shape. The so-called "four colors" means that the color of the root bark has white, purple, green, pink, etc. four colors. China is the first country in the world to cultivate white radish. After several hundred years of development, many types and different quality white radishes have appeared on the market, and because the roots of white radish seeds are rich in oil, they can reach about 40%. Therefore, in addition to having an edible function, white radish is also commonly used to make lubricating oil.
2 Research on the development value of white radish
2.1 Nutritional value
The nutritional value of white radish is extremely high, mainly in the root and leaf. At the root of white radish, it contains the nutrients needed by the human body, such as vitamin C, crude fiber, sugar, protein, etc., and does not contain oxalic acid. In the leaves of white radish, it also contains extremely rich calcium, which is more than three times more than spinach. Eating white radish not only prevents vascular arteriosclerosis, but also has a certain anti-cancer effect.
2.2 medicinal value
Modern medical research shows that white radish has significant medicinal value, among which the more prominent effects include: First, white radish has significant anticancer effect. The rich enzymatic components contained in it can effectively decompose nitrosamines with more carcinogenic effects, and thus have a certain effect on inhibiting cancer. At the same time, eating white radish can also enhance the vitality of human macrophages and strengthen their ability to phagocytose cancer cells; second, calcium supplementation. The leaves of white radish are rich in calcium, which can effectively supplement the calcium substances needed by the human body. Third, the antihypertensive effect. In traditional Chinese medicine theory, eating white radish can play a role in lowering blood pressure and treating cough. Fourth, treating tuberculosis. The white radish is made into a radish honey cream, which can be used for treating tuberculosis hemoptysis.
2.3 Edible value
White radish itself is an edible vegetable, so it is naturally edible. In modern catering, the edible value of white radish is more obvious. For example, when the white radish is chopped out of the juice and added with a small amount of rock sugar, it can achieve the effects of lowering fat, detoxifying and preventing cancer by drinking in the morning and evening. At the same time, the methods and methods of using white radish are various, and can be stewed into radish soup. Into the radish dumplings, can also be marinated into dried radish, made into radish and so on.
3 Cultivation techniques of white radish
Through the long-term cultivation practice of white radish, the key points of cultivation techniques of white radish are summarized, namely, “four key pointsâ€, “six key points†and “five jointsâ€.
3.1 "Four Keys"
3.1.1 Temperature
Packed with radish, it is warm and cool, and it is a semi-hardy vegetable. During planting, attention should be paid to temperature control. The seeds can germinate at 2~3°C, and the optimum temperature is 20~25°C. The plant seedling period can be short-term resistant to low temperature of about -2°C and high temperature of about 25°C. The suitable temperature is 15~20 °C, and the optimum ground temperature for root growth is 13~18 °C.
3.1.2 Lighting
White radish requires adequate lighting conditions. When the light is sufficient, the photosynthesis is strong, the roots grow fast, the material accumulation is large, the yield is large, and the quality is high. vice versa.
3.1.3 Moisture
Due to the large size of the leaves, although the roots of the white radish are deep, they also exhibit drought tolerance. During the planting process, soil moisture of 65% to 80% of water holding capacity and air humidity of 80% to 90% should be maintained.
3.1.4 Soil
Before planting white radish, make sure that the impurities in the soil are effectively removed to prevent soil-borne diseases. At the same time, the soil needs to be improved. For example, maintaining the soil p H value of 5.3-7.0 to ensure sufficient potassium and phosphorus in the soil. Ensure the depth of the soil layer and have good drainage.
3.2 "Six off"
3.2.1 茬å£å…³
As far as possible, plant white radish in the land where the beans or melon crops are mainly grown, so as to ensure sufficient soil fertility and ensure good growth of white radish.
3.2.2 Land preparation
We will carry out land consolidation by deep ploughing and high ridges, and at the same time strengthen soil and fertilizer management.
3.2.3 Variety off
According to the difference of different regions and different seasons, choose the suitable planting varieties.
3.2.4 Sowing date
Summer radishes should be planted around June, and autumn radishes are planted around August and September.
3.2.5 Seeding rate
In summer, the amount of radish seeded is 4 per hole, and the amount of radish in autumn is about 6 seeds per hole.
3.3 "Five Combinations"
3.3.1 Intercropping
According to the principle of staying good and getting worse, the seedlings are planted, and the weak plants of the weak plants are removed in time.
3.3.2 Watering
Combine the growth cycle and growth state of the seedlings, and timely and appropriate watering.
3.3.3 weeding
The weeds in the plots are removed in time to ensure that the soil has a certain permeability.
3.3.4 Pest Control
Implement scientific pest and disease control work at different stages, and strengthen daily management, mainly adopt biological and agricultural methods for controlling pests and diseases, and take appropriate chemical control measures such as pesticides.
3.3.5 Harvest
Observe the growth of white radish in time, and once it meets the market's edible requirements, it can be harvested.
In summary, white radish is a kind of vegetable with edible value, medicinal value and nutritional value. It is widely cultivated in China and has a long history of cultivation. It is necessary to follow strict techniques for its cultivation and cultivation. Therefore, relevant plantation managers should pay more attention and attention to this.
