Pests and diseases are not prevented. Although there are many pests and diseases on jujube trees, as long as you carefully observe and keep records, you can find that the occurrence time of pests and diseases is time-dependent and regular, and changes in weather play an absolute role in the occurrence of pests and diseases. As long as the time and regularity of the occurrence of pests and diseases are ascertained, and the symptomatic drug spraying is used, the pests and diseases can be eliminated at the initial stage. At present, some jujube farmers do not prevent pests and diseases in management. Once the pests become widespread, they will rush to prevent and control them, which not only wastes financial resources and manpower, but also fails to receive good results. There are also some jujube farmers who use drugs indiscriminately for pest control and disease prevention, and the phenomenon of unpreventable pests and diseases is widespread, resulting in long-lasting pests and long-lasting cures. Xia Guan Bu Xia cut jujube trees Xia Guan refers to the processes of wiping buds, pinching heads, putting branches and branches, girdling and cutting, and its purpose is to produce more fruits and produce good fruits, but jujube farmers ignore an important link. , That is Xia Jian. The fruiting parts of jujube trees are mostly around and on the crown. The fruiting branches of the inner chamber and the branches at the bottom often bloom early and bear fruit early. If they are not cut in time in summer, the bottom and inner parts will be caused by the advantages of the top and the light. The jujube fruits on the branches of the chamber fell one after another. The branches do not renew and the crown does not open. The fruiting branch of the jujube tree has a high yield period of about 5 years, and the fruiting branch group of more than 5 years will gradually age, easy to germinate the jujube, and it is easy to produce multiple jujube hangings. The jujube fruit produced is small in size and poor in quality. The jujube fruit is not nutritious due to the competition between the jujube fruit and the jujube fruit, resulting in serious physiological fruit drop. Therefore, old branches must be renewed in time, which is the basic guarantee for prolonging the productive years of jujube trees.

Four Misunderstandings in Jujube Management
One type of unreasonable fertilization is the application of base fertilizer. If you apply enough fertilizer at one time, topdressing will not be done in the later period. The second is not to apply base fertilizer, and then topdressing after the results. The third is to fertilize in stages, the method is correct, but the fertilization is too single, most of which are nitrogen fertilizer, which causes the jujube to grow leaves without fruit. Jujube gardens with partial application of nitrogen fertilizers have fast growth of new branches, extended jujube hangings and light green leaves; jujube gardens with partial application of phosphate fertilizers have thick and dark green leaves, short jujube stocks indirectly, and jujube stocks are easy to age; jujube gardens with excessive potassium The leaves are narrow and it is not easy to shoot new branches, which is unfavorable for future crown renewal and crown expansion. Therefore, the fertilization must be properly matched. If one type of chemical fertilizer is applied, it will lead to nutritional imbalance of the jujube tree, resulting in flowerlessness, serious flower and fruit drop, etc.
