The period from peach fruit picking to defoliation is the key period for peach nutrient accumulation and flower bud differentiation. The management will directly affect the peach wintering ability and the second year's growth results. Therefore, fruit growers should pay attention to the management of peach trees after fruit harvesting.
First, timely fertilization before falling leaves after harvesting fruit, in particular, the results of excessive trees should be applied early, late-maturing varieties of fruit before harvest. The types of fertilization were mainly mixed with high-quality organic fertilizers of nitrogen, phosphorus and potassium compound fertilizers and micro-fertilizers. In case of autumn drought should be timely irrigation. In addition, it can be combined with sprays for top dressing and nutritional supplementation.
Second, spraying, in order to protect the leaves, it has a strong photosynthesis, is conducive to the accumulation of nutrients. After harvesting fruit, we should focus on the prevention and control of peach leaf perforation, peach aphid, red spider and leaf miner. Control: 50% carbendazim 800 times solution is available, plus 40% Dimethoate 1500 times solution.
3. Pruning: Peach trees are easily hollowed out, except for cross-branches, overlapping branches, diseased shoots, and thin and weak branches in the canopy. The remaining branches often use short-truncated shoots, usually for long-medium-growth long fruit shoots. Appropriate short cuts, let the results, and select the new shoots near the backbone of the branch for heavy short cuts, making it a new branch of fruit. At the same time, the retraction of the branches caused the lower single buds to draw strong branches.
Fourth, weeding and weeding, peach trees shall be cultivated and weeded in time after harvest, with a depth of 10-20 cm. After defoliation and early clearing of the garden, weeds and deciduous trees are buried under the trees after spray and pest control.
