Soil is the basis for the growth and development of jujube trees. The purpose of soil management is to maintain and improve soil fertility, fully expand the roots of jujube trees, and absorb enough nutrients and water to meet the needs of jujube growth and results. Soil management includes deep-ripening, intertilling and weeding, shavering, soil and water conservation, and intercropping of jujube gardens.
First, deep-turning and cultivating weeding For the jujube garden, we should plough and pour the soil once in the early spring or late autumn. The purpose is to increase the soil permeability, increase the temperature, and facilitate the growth of the root system. When the deep roots are cut off, part of the fine roots can cause new roots to occur, and it can also eliminate underground overwintering pests. Generally, the depth of cultivation is 20 to 30 cm. In the growing season, weeds and jujube trees compete for water and nutrients, and we need to carry out cultivating and weeding. Through cultivators, we can also protect leeches.
As for the mountain jujube gardens, because the soil layer is thin, the growth results are often unfavorable. Through the deep turning of the soil, the growth of jujube trees can be promoted and the yield can be improved. However, in the mountainous area, the parent rock is hard and difficult to deepen. It is possible to use a shotcrete to expand the loose soil of the hole. This method is used to make a hole in the periphery of the canopy. The depth of the blasthole is 80 to 100 cm. The dose depends on the soil parent material. Gun-made ammonium nitrate explosives 0.4 to 1.0 kg, each gun can collapse 1.2 to 1.5 meters deep, affecting the range of 3 to 4 meters.
Therefore, the distance between the borehole and the trunk should be 3 to 4 meters, and the tree is not broken. After blasting, large stones are pulled out, combined with loose soil, organic fertilizer 1200 to 1500 kg per 667 square meters of jujube, leveling After watering. The suitable period for the blasting of the caverns is the period from autumn leaves to spring before germination.
Second, the purpose of the shaver is to thicken the living soil layer, improve the soil, and eliminate the underground overwintering pests. The period of shavering is in the late autumn and early winter or in early spring. The method is to shave 15-30 cm soil layers with iron shovels in the range of 1 to 3 meters around the tree trunk, near the trunk, and deeper outwards to avoid hurting the root system. , while removing unnecessary roots.
3. Soil and water conservation The jujube gardens in hilly and mountainous areas have serious soil erosion, which often results in weak tree vigor and low yield. Therefore, soil and water conservation work must be strengthened. The main measures are to renovate terraced fields, raise water sluice, and dredge catchment ditch.
4. Intercropping Green Fertilizer Zaoyuan Intercropping green manure can not only provide jujube fertilizer, but also play a role in preventing water and soil loss, preventing wind and sand, and stabilizing soil temperature. The intercropping green manure needs to have a certain distance from the jujube tree, otherwise it will compete with the jujube tree for fertilizer and water, and the green manure should be castrated in time, and the manure can be used for overturning or manure, and can also be used to cover the tree plate. There are many green manure plants suitable for the intercropping of jujube gardens, such as grass cedar, ramie, and Sesbania.
5. Intercropping of jujube and grain intercropping Intercropping of grains and grains is an agricultural system created by the working people in China. It is a model for three-dimensional agriculture because jujube trees have the characteristics of late sprouting, early deciduous leaves, small leaves, sparse roots, and sparse root distribution. When food and other crops are intercropped, the contradiction between fertilizer, water and light is not very prominent. By choosing suitable crops and corresponding cultivation techniques, it is possible to basically solve the contradiction between fertilizer and water.
The layout of jujube grain intercropping has formed a new agricultural ecosystem. Compared with monoculture crops, the wind speed and temperature of intercropping grains are reduced, the humidity is increased, and the damage of dry hot wind is reduced. This provides the growth and development of both crops and jujube trees. Good environmental conditions, so that the harvest of both dates. Crops suitable for intercropping with date trees include wheat, beans, peanuts, sesame, and cotton.
Covering the grass under the canopy or covering the entire park with weeds, green manure, crop stalks, etc. The thickness of the cover is generally 20-25 cm. The effect is to inhibit weed growth, reduce water evaporation, prevent soil erosion, and increase soil organic matter. content. Http://Content/9ffa7d93-99cc-4436-b097-f4befba0473e?cType=2
