After harvesting the greenhouse, the peaches can be uncovered. After the removal of the film, management must continue to be carried out in order to prolong the life span of the leaves, prevent the leaves from falling off, increase the photosynthetic accumulation, and promote the differentiation of flower buds. This will lay the foundation for high yields in the following year.
First, the purpose of trimming and trimming in summer is to control the length of branches and make the crowns airy and transparent. Can take branches, branches and other measures, the upright branches, growing over Wang branch into a close level, over dense branches appropriate thinning.
Second, pest and disease prevention after spraying a 500-600 times 70% mancozeb or 700 times 50% carbendazim, spraying 2-3 200-240 times the same amount between July and August Bordeaux's solution to prevent diseases on leaves and stems, and to prevent leaf caterpillars and moths.
Third, the management after falling leaves should be filled with water once before deciduous freezing. In the winter, the tree for the early fruit period is mainly to complete the plastic surgery, to cultivate robust fruiting branches and to expand the canopy. Dormant pruning is to adhere to the principle of more hands and less dynamic shear, try to keep more branches, mainly to slow release, with the first method to cultivate the results of the first postponement of the sticks, only to the main branch extension head left full bud short. For fruit trees, a large number of fruit-like branches and short fruit branches should be appropriately sparse, and medium and long fruit branches should be appropriately short-cut. For trees with consecutive years of results, such as tree weakness should be renewed in batches in order to rejuvenate the tree.
Fourth, fertilizer and water management combined with soil ploughing for early autumn fertilization. After the fruit is harvested, the temperature is slightly higher and the sunshine duration is longer. Post-harvest fertilization can significantly promote photosynthesis, increase storage nutrition, promote flower bud differentiation, improve flower bud quality, and increase its overwintering quality. Decomposition of chicken manure can be applied to 10-20 kilograms, plus about 0.5 kilograms of nitrogen, phosphorus and potassium compound fertilizers, and irrigation should be performed after fertilization. In order to improve the photosynthetic performance of its leaves, photosynthetic micronutrients can be sprayed on the leaves, and the concentration is generally about 0.3%.
