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.
Before harvesting, timely fertilization should be performed before falling leaves, especially if the tree with excessive results should be applied early, and the late-maturing varieties should be harvested before harvesting. 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.
Spraying medicine to protect the leaves has a strong photosynthesis and 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.
Pruning, peach trees are easily hollowed, except for cross-branches, overlapping branches, diseased shoots, and thin and weak branches in the canopy. The rest of the branches are often short-truncated, usually short for moderately growing long-fruiting branches. Cut, let the result, and select the new shoots near the backbone to make heavy short cuts, making it a new result of the branches. At the same time, the retraction of the branches caused the lower single buds to draw strong branches.
Weeding and weeding, peach trees should be cultivated and weeded in time after harvest, with a depth of 10 to 20 cm. After defoliation and early clearing of the garden, weeds and deciduous trees are buried under the trees after spray and pest control.
