After the peach fruit is picked, the assimilation of the leaves continues, and nutrients begin to accumulate in the tree. This stage is also the flower bud differentiation period. From the fruit harvest period to the deciduous period, the number of tree nutrient accumulation and the quality of flower bud differentiation are closely related to the yield and quality of peach fruit in the next year. Therefore, after the peach fruit is removed from the tree, management has not ended and it still needs strengthening. After applying the fruit tree, the tree body consumes a lot of nutrients and must be supplemented with nutrients in time to restore the tree vigor, enhance the light and the ability of the leaves, enhance the accumulation of nutrients in the tree, ensure adequate nutrient supply and flower differentiation, and increase flower buds. Quality and ability to withstand cold in winter. After the fruit is harvested, 0.5 kg of urea is planted in each tree, and 0.2% potassium dihydrogen phosphate solution is sprayed on the leaves for 2 to 3 times. After the prevention and control of pests and peaches, the peach leaves will be endangered by various diseases, leaf miners and leafhoppers. If they are not controlled effectively, the peach leaves will be damaged and they will fall off earlier, affecting the accumulation of nutrients and flower bud differentiation. Therefore, attention should be paid. Check and promptly prevent and treat. For insect pests, they may be sprayed with liquids such as dichlorvos and dimethoate. For diseases, a fungicide should be sprayed every 10 to 15 days after picking, and 70% thiophanate-methyl wettable powder 800~ can be sprayed alternately. 1000 times liquid, 65% mancozeb wettable powder 500 times liquid and 30% green decoction 400 to 500 times liquid. Reasonable Pruning Peach After picking, the growth of new shoots is accelerated, the ability to form secondary shoots is strong, and it is easy to cause poor ventilation, increase nutrient consumption, affect flower bud differentiation, and must be reasonably pruned. For strong twigs or branches in the upper part of the canopy, they can be sprained and pressed down from the base after removing the strong shoots, so that the growth potential of the basal part can be controlled, and nutrition can be concentrated to provide flower bud differentiation; for the competitive twigs, sprains can be used to control growth. Want to result in branch transformation; for overlapping branches, cross branches and old and weak branches, to timely retract; for too dense branches, thin branches and useless standing Wang branches, to be removed; for space reservation of standing Wang branches, can be Press in the crown to ease its growth potential. Shallow tillage cover grass After picking the fruit, the garden soil is dug by 10 to 15 centimeters with a four-toothed nail, and a thin layer of straw or wheat straw is spread after digging. In this way, the soil is loosened, the aeration of the soil is increased, the growth of the root system is facilitated, the weeds are eliminated, and the soil organic matter is enriched. Drought-resistant peach trees have a shallow root, which is both afraid of drought and afraid of stains. Therefore, in summer and autumn drought should be timely irrigation and drought; if it comes into contact with rain, it is necessary to clear the trench drainage. The use of base fertilizers in the fall combined with the use of basal fertilizer deep-turning soil can improve the soil structure and physical properties of Taoyuan, increase soil fertility and water retention capacity, and create favorable conditions for root growth. The application of basal fertilizer can increase the storage of nutrients in the tree and lay a solid foundation for the high yield of peach fruit in the next year. From the outer edge of the planting hole, dig deep trenches of 80 cm in width and 50 cm in width. During the period from November to November, 20-30 kg of pig cow manure was applied to each tree and 1 kg of phosphate fertilizer was applied. Phosphate fertilizer is best mixed with organic fertilizer before application, and then stacked for more than half a month. When applied, it is mixed with surface soil and filled into the ditch to fill the surface with the earth and soil.
