1, adjust the amount of tree branches. After peaches are harvested, thinning or short cuts should be carried out on branches and branches that are too dense and weak, in order to open the light path and enrich the branches, reducing unnecessary consumption. This will not only help the flower buds continue to differentiate and enrich and shoot mature, but also reduce the amount of winter pruning. 2, control of pests and diseases. Peach leafhopper, also known as swiftlet, is the major pest in the late peach trees. It is the most serious pest from July to September. Yellow and white spots appear on the damaged peach leaves. When it is severe, the whole leaves are yellow and fall off early, affecting flower bud formation and causing tree vigor. Weak, reducing the output in the coming year. Control method is to use 10% imidacloprid 3000 - 4000 times liquid plus 50% malathion EC 2000 times spray, the effect is very good. 3, foliar spray fertilizer. Fertilizer spraying is not only used for the early growth period, but also very important in the later period. Therefore, from the peach harvest, 0.3%-0.5% urea plus 0.3%-0.5% dipotassium hydrogen phosphate should be sprayed once every 10-15 days to increase the photosynthetic capacity and increase the shoot nutrition. 4, autumn basal fertilizer. In particular, the park with more results should be applied earlier. The basal should not be late as early as possible. The fertilization method can be applied alternately radially and circularly. The position should be at the outer edge of the canopy, and the depth should be shallow and deep so as not to break too many roots, and then watering once. 5, fall over the tree plate. Many overwintering larvae and crickets are concentrated in the ground within 10 centimeters of the canopy and overwinter. After turning over the tree, a large number of pests can be eliminated.
