How to manage the jujube garden in summer?

How to manage the jujube garden in summer? Please introduce the summer jujube garden management can refer to the following methods: first, topdressing. Jujube topdressing is generally applied twice, that is, pre-flowering fertilizer and young fruit fertilizer. The purpose of pre-anthesis fertilizer is to promote the rapid growth of new shoots and young fruits and to increase the fruit setting rate. More nitrogen fertilizer should be applied. Generally, about 0.5 kg of urea is applied per plant before flowering. The purpose of young fruit fertilizer is to promote the rapid expansion and weight gain of fruit, improve the quality and sugar content, apply more phosphorus and potassium fertilizer, and apply about 1 kg ternary compound fertilizer per plant in the young fruit stage. In addition, foliar fertilization should be done, that is, 0.5% urea and 0.3% potassium dihydrogen phosphate solution should be sprayed before flowering and young fruit stage, and 0.3% borax solution should be sprayed at flowering stage, which can significantly increase the fruit setting rate. Second, watering. Jujube trees need sufficient water in the early stage of growth, especially in flowering and young fruit stages, and should be watered twice according to weather conditions. Watering at flowering stage can increase air humidity, facilitate pollination and fertilization, and improve fruit setting rate. Watering in the young fruit stage can prevent the fruit from wilting and promote the growth and development of the young fruit. Third, summer pruning 1, ring peeling. It can reduce flower and fruit drop, increase fruit setting rate, promote fruit hypertrophy, improve fruit quality and promote fruit ripening. Generally speaking, after more than ten years, the crown is basically formed before it can be peeled around. Girdling prematurely will inhibit the further expansion of the crown or the phenomenon of premature senility. The time of girdling should be in the early stage of flowering and should be carried out every other year. The specific method is that for the first time, on the trunk 30 cm from the ground, the trunk bark is scraped off once, about 1 cm wide, and then girdled. The principle of "heavy peeling of strong trees and light peeling of weak trees" should be grasped. The width of the general ring peeling mouth of strong trees is 0.6-0.7 cm, and that of weak trees is 0.3-0.4 cm. After the next year, the ring stripping is carried out at 3-5 cm above the last ring peeling. Gradually ascend along the trunk in turn. For too weak trees, they will no longer be girded, and will not be carried out until the tree is restored. It should be noted that girdling should be carried out on a sunny day, wide outside and narrow inside, and wrapped with plastic film one week after peeling with insecticide. Girdling must be combined with strengthening water and fertilizer management, otherwise the growth of the tree will be affected. 2. Thinning branches. Remove dense branches and erect overgrown branches in time before flowering, and remove weak hanging and empty hanging on jujube stock during ring peeling period. 3. Pick the heart and wipe the bud. It can improve the nutrition level of branches, ease the contradiction between new shoot growth and fruit, and increase yield obviously. the cutting tip is generally carried out at the flowering stage, leaving 3-5 short secondary branches for jujube heads issued in spring, and coring the secondary branches. When the fruit enters the young fruit stage, hit as soon as you see the tip, and wipe the useless buds on all levels of backbone branches when you see the buds, so as to save nutrition, improve light and increase the fruit setting rate.
