After the peach fruit is harvested, the tree body is weak. At this time, the focus should be on strengthening the tree management to lay a good foundation for the next year's high yield. A few days ago, the reporter interviewed Han Mingyu, a professor at the College of Horticulture of Northwest A&F University, and asked him to give the fruit farmers how to manage the peach trees after harvesting them. Fertilizer management Peach trees should be topdressed and foliar sprayed in time. The topdressing should be based on nitrogen fertilizer. The root dressing can spray 0.3% potassium dihydrogen phosphate every 15 days for a total of 2 to 3 times. At the same time, the fruit farmers should carry out deep ploughing after fruit picking, combined with the application of base fertilizer, the base fertilizer is mainly organic fertilizer, and the application rate is 2 to 3 times of the yield. In addition, the frozen water must be sealed before freezing. Peach trees are not resistant to cockroaches. If the peach gardens accumulate water for a short period of time, they will cause yellow leaves, fallen leaves, and even rotten dead trees. Therefore, we should pay attention to the elimination of stagnant water during the flood season. After pruning peach trees in autumn, the growth of new shoots is large, and the ability to form secondary shoots is strong. It is easy to cause internal stagnation and closure, affecting flower bud differentiation, and should be carried out in autumn. For the strong wangwan branches or branches in the upper part of the canopy, after the strong shoots are removed, the roots are sprained and pressed down; for the competitive branches, the twisting method can be used to control the growth and transform them into the result branches; The cross branches and the old weak branches should be retracted in time; the dense branches, the weak branches and the useless erect branches should be removed; for the erected branches with space preservation, they can be pressed down in the crown to ease their growth. Immediately after pest control, 65% mancozeb 400-500 times solution and 2.5% cypermethrin 2500 times solution are sprayed to control leaf diseases and leaf miner pests, and other pests and diseases should be prevented in time.
