The overall pruning short cut object is a peach tree with long fruiting branches. The top of the long fruiting branches is generally not the result, and the middle flowering buds are numerous and the result is, so the ineffective part of the top is cut off. Cut 1/3 of the branch length when trimming. Among them, the long fruit branch with weaker growth should be short and heavy; the growing fruit should be strong and the long fruit branch with the upper part of the flower bud should be light and short. In long fruiting branches, branching should be generally reserved in oblique or horizontal state, and erect branches or pendulous branches should be removed. Partial upright branches should be appropriately reserved in old trees. In addition to dense branches in middle and short branches, they should be sparsely cut and generally not truncated. Stable and upright growth, good lighting conditions, and the branches of the lateral branches at the tips of the branches, can be retained 12-15 centimeters for short cuts, for new shoots. For long-term branches that have been aging for many years, they should be shortened and renewed so that they can be re-extracted into long branches, and then medium and short fruit branches can be formed. The main objects of thinning pruning are saplings and wangshu trees, which can significantly ease the tree vigor and promote its early results. The saplings should mainly be devoid of drooping branches, thin and weak branches, competing branches and leggy branches. It is also possible to use secondary branches to enlarge the crown or promote its transformation into a result branch. The canopy of the adult result tree has been shaped, and a combination of truncation and debriding can be used to control the strong and weak, mainly densely cut branches, thin branches, overlapping branches, branches and branches, straight branches and leggy branches. Deeply turn over the garden to deepen and turn over the soil to improve the shallowness of the Taoyuan soil. Deepen the soil by expanding the hole within 2-3 years after planting. Dip at a depth of 50 cm and a depth of 50-60 cm under the canopy drip line. Also shallow 10-15 cm to improve the growth conditions of the root system. At the same time, combined with the application of basal fertilizer based on farm organic fertilizer. The amount of fertilization depends on the age, growth and growing conditions, but the amount of basal fertilization should account for more than 60% of the total fertilization for the whole year. Qingyuan combined with pruning, all clear the ground on the branches and branches of litter, litter, concentrated burning, in order to reduce the source of the disease. After pruning the pests and diseases, peaches should be sprayed with Baume 5 degree lime sulfur and 0.3% sodium pentachlorophenol in time to prevent overwintering diseases and insect pests. The main branch of the peach trunk is to be painted white, and plants with gums must be scraped first and then whitened. The proportion of whitening agent is 12 parts of quicklime, 2 parts of clay, 2 parts of lime sulfur, 1 part of salt, and 40 parts of water. After mixing, it is painted white and can be painted from top to bottom. The amount is not suitable for downstream. . Article Source: "Rural Information News" China Agriculture Network Editor
