After pruning the peach trees after harvesting, the summer pruning should be carried out in time. In the case of a spindle-shaped tree, the upper competing branches or overly dense branches on the trunk should be removed. The shape of the happy tree should be cleaned up and the branches of the branches should be cleaned, and some of the branches should be thinned to support the tree and restore the canopy as soon as possible. In the summer, measures such as topping and cutting are taken to cause secondary branches to be converted into result branches. On the one hand, in the autumn, the branching is carried out, mainly to adjust the direction and angle of the branches, to extend the branches, and to promote the branches; on the other hand, the measures of thinning are adopted to mainly remove the dense branches and long branches, improve the lighting conditions of the canopy, and promote nutrition. Growth to flower bud differentiation and transformation. After spraying and spraying the paclobutrazol fruit, the new shoots should be controlled by paclobutrazol to promote flower bud formation. Beginning in mid-June, continuous spraying of 15% paclobutrazol solution 300 ~ 500 times solution, the peach tree should be sprayed 2 to 3 times continuously, spray the cloth to the Zhongyong tree 1 or 2 times, the spray cloth should be uniform. Fertilizing and watering 1. Topdressing. After extracting the film, the fruit compound organic compound fertilizer should be applied in time to reduce or not apply nitrogen fertilizer, and increase the amount of phosphorus and potassium fertilizer. Topdressing should be based on the size of the tree. In addition, root dressing can also be carried out, spraying photosynthetic micro-fertilizer or 0.3% urea plus 0.3% potassium dihydrogen phosphate solution every 10 days or so, which can be sprayed separately or in combination with spraying. 2. Drain irrigation. Peach trees are afraid of cockroaches, so it is necessary to pay attention to drainage in the rainy season, especially in plains and clays, to prevent accumulation of roots and damage to the growth of the aboveground parts.
