How to reduce and prevent jujube disease pests: Dongguan Maimeng Cultural Communication Co., LTD , http://www.aiberrycn.com
Ecological prevention to reduce disease must begin with management. In the management process of jujube trees, fertilization is an important link. Scientific fertilization, organic fertilizer-based, inorganic fertilizer supplementation, balanced fertilization, preferably using soil testing formula fertilization, not only saves costs, but also increases economic benefits. Pay attention to the application of organic fertilizer. If there is no farmyard manure, you can use bio-organic fertilizer with new high-fat membrane for application. The new high-fat membrane makes the soil loose and transparent, and improves the utilization rate of fertilizer.
If farmyard manure or bio-organic fertilizer is used as base fertilizer, it must be applied in depth. The farmyard manure should be used with a certain proportion of NPK fertilizer, and the effect is better. In the later stage, according to the growth of jujube trees and the amount of fruit hanging, the topdressing is selected in a targeted manner. The topdressing fertilizer is mainly based on phosphorus and potassium fertilizer, and it should be applied to the root system to facilitate absorption. After the jujube fruit enters the expansion period, the foliar spray of Zhuangguo Tieling has a certain effect on jujube fruit expansion and quality improvement.
Through reasonable fertilization, the soil structure is completely changed, the jujube tree potential is enhanced, the jujube tree body's own ability to resist pests and diseases is improved, and other agricultural management is strengthened, the drug control is reduced, the cost of prevention and control is reduced, and the quality of jujube fruit is improved.
