How to fertilize jujube trees?

How to fertilize jujube trees? Please describe the method In the process of jujube management, fertilization is an important link, just like people want to eat, not only to eat but also to stress comprehensive nutrition, health, disease prevention, jujube is the same. However, in recent years, due to the return of farming, farm manure has been greatly reduced, most jujube farmers have not applied organic fertilizer to jujube trees for many years, only applied nitrogen, phosphorus and other inorganic fertilizers, resulting in the reduction of soil organic matter, unbalanced soil nutrients, changes in soil aggregate structure, changes in soil acidity and alkalinity, soil hardening, decreased ventilation and water permeability, decreased soil fertility and water retention capacity, jujube roots can not fully absorb nutrients and water, growth period can not meet normal growth needs. Jujube trees are strong outside and weak inside, and their disease resistance is reduced, which eventually leads to the decline of fruit quality and benefit. At the same time, due to the change of soil structure, the applied elements such as nitrogen and phosphorus are also adsorbed and fixed by the soil, which cannot be absorbed and utilized by jujube trees, resulting in a large amount of waste. Therefore, remind the majority of jujube farmers to change their understanding, scientific fertilization, organic fertilizer as the main, inorganic fertilizer as a supplement, balanced fertilization, it is best to use soil testing formula fertilization, both to save costs and increase economic benefits. Pay attention to the application of organic fertilizer, no farm manure can choose biological organic fertilizer, biological organic fertilizer in addition to containing organic matter and other nutrients, but also contains microbial fungi, beneficial bacteria can activate the soil, make the soil loose and transparent, but also can release the elements such as nitrogen and phosphorus fixed by the soil, improve the utilization rate of chemical fertilizer. Farm manure or biological organic fertilizer as base fertilizer application, must be applied deeply, farm manure should be combined with a certain proportion of nitrogen, phosphorus and potassium fertilizer use, the effect is better. In the later stage, according to the growth of jujube trees and the amount of fruit hanging, there is a targeted choice of topdressing, topdressing mainly phosphorus and potassium fertilizer, which should be applied near the root system to facilitate absorption. After jujube fruit entered the expansion stage, foliar application of potassium fertilizer and calcium fertilizer had certain effect on jujube fruit expansion and quality improvement. Through rational fertilization, thoroughly change soil structure, strengthen jujube tree vigor, improve jujube tree self disease and insect resistance ability, strengthen other agricultural management, reduce drug control, reduce control cost and improve jujube fruit quality.
