After the peach tree results, a lot of nutrients were consumed. After the peach harvest, the rainy season happened. If we can strengthen the technical management in time, we can increase the tree's nutrient accumulation, restore the tree vigor as soon as possible, and form a good flower bud, in order to improve the next year's Peach yield and quality create favorable material conditions. Floating life-saving rope on the water surface, also known as floating rescue rope, water life-saving rope, etc. It is often used in water entertainment venues, lake water rescue and flood natural disaster rescue. The water life-saving rope is long equipped with a floating ring and a floating ball, which is equivalent to the rescue and disaster relief accident.

1, underground fertilizer management. Through the underground fertilizer and water management, the tree body can quickly absorb and replenish nutrients. After the peach is harvested, the top-dressing fertilizer can be top-dressed in a timely manner. The urea 0.25kg per plant in the first fruit tree and 0.5kg per plant in the mature tree. It is necessary to control the use of nitrogen fertilizers to prevent shoots from becoming long and affect flower bud differentiation. A green manure was pressed in July. Combine pest control with foliar spray fertilizer. Use 0.3-0.5% urea solution in July and 0.3-0.5% potassium dihydrogen phosphate solution in August-September, each time for 15 days. From September to October, a basal fertiliser was applied in combination with deep plowing and hoeing. The farmhouse organic manure was fully decomposed, supplemented by ternary compound fertilizer. For the first fruit tree, 50-100 kg of organic fertilizer is applied per plant, 0.5-1.0 kg of ternary compound fertilizer, 100-200 kg of organic fertilizer per plant and 1 to 2 kg of ternary compound fertilizer. Fertilization method can be used with ring groove or radial groove, fertilization depth 30 ~ 50cm.
Peach generally receives more rain after harvesting, but it is not necessary to water. If the drought is too long, it can be filled with water as necessary. During the rainy season, we must discharge water to prevent flooding, cultivating and weeding to prevent soil compaction, and freeze the water before the soil is frozen.
2, trim. Through pruning, the trees are allowed to air and transmit light, promote photosynthesis, and form good flower buds. Firstly, the dense branches, the branches of diseases and insects, the branches and branches, the overlapping branches, and the thin and weak branches were removed to improve the light conditions. Soften the angle of the upright backbone and ease the tree potential. For the erect leggy branches on the back, there is the softening or twisting of the growth space, controlling its growth potential, cultivating the resulting branches, expanding the area of ​​results, and eliminating the growth space. The weak branches that droop after the result can be properly retracted to reduce nutrient consumption and promote its rejuvenation. Long fruiting branches can be appropriately shortened and cultivated into compact fruiting groups. At the end of September, topping the uncapped shoots once again to promote the growth of the tissue.
3, chemical regulation. For overgrown trees, paclobutrazol can be sprayed on the crown to control vegetative growth and promote flower bud differentiation. The method is to spray 15% of paclobutrazol 15% 300 to 500 times solution 1 to 2 times when the new shoot length reaches 30cm and the second branch is to be drawn.
4, control of pests and diseases. The major pests and diseases after peach harvesting are bacterial perforation, aphids, leafminers, and red spiders. The prevention and treatment of bacterial perforation should be based on prevention. From the beginning of June, foliar spray of zinc sulfate lime solution is used. The ratio is zinc sulfate: quicklime: water = 0.5:2:120, once every 15 days. 4 to 5 times; aphids can be controlled with 10% imidacloprid powder 3000 times or 25% hydrazine eugenol 2000 times; leaf miners can be controlled with 25% diflubenzuron 3 times 1000 times; red spider can be used 20% of the Sustained-killed Suspension 3000 times or 1.8% of the Qishensu Emulsion 4000-fold, or 30% of the Mothraxine 2000 times. Convection plastic disease, first, to avoid damage to the branches of the mechanical damage; Second, the flow of glue on the branches after scraping, with lime 10 parts, 1 part of lime sulfur, 2 parts of salt, 0.3 parts of vegetable oil plus appropriate amount of water Into the protection agent, smear the affected area or cut the mouth can be. Autumn white coating can reduce the temperature difference between day and night, prevent frost damage and daily burning, and also can kill pests and diseases on the trunk. The ratio of the mixture is quick lime:lithium mixture: salt:water = 5:1:1:20, a little clay. Spread the prepared whitening agent evenly on the trunk without flowing down. Be careful not to coat the shoots to avoid burning the buds.
