In order to achieve high yields of chestnuts in successive years, it is necessary to break the practice of only harvesting chestnuts, especially chestnut trees in the fruiting period, and to do good post-harvest management; otherwise it will affect the yield and quality of chestnuts in the next year. The management techniques of winter chestnut are introduced below. Fertilize. Generally, the main application is organic fertilizer with a small amount of chemical fertilizer. Fertilization is used in conjunction with root irrigation and root irrigation to cultivate soil moth to facilitate root absorption and quickly restore tree vigor. Scraping. If the tree is more than 10 years old, you can scrape it. The peeling time should be the best after picking the fruit. For cold areas, it is generally appropriate to scrape it in early spring. Coarse skin and warped skin on the trunk and main branches of fruit trees are wintering places for pests. When scraping the skin, the underside of the trunk should be covered with plastic to scrape off the rough skin, old skin, and warped skin with a sharp knife, and take it outside the park to burn it. After scraping the skin, brush the trunk and the branches in time to protect the tree generals and white agent to prevent pests or germs from infecting the trunk. prune. For 5 to 6-year-old chestnut trees, after pruning and shaping, only the sprouting branches and lower branches at the base are cut off. The dry branches, dead branches and diseased branches that have appeared must be cut off. For crowded overlapping branches and over-dense branches of adult and old trees, it is necessary to properly remove the overlapping bores and dense branches, so as to promote good ventilation and light transmission of the crown, and three-dimensional results. For senescent chestnut trees, it is necessary to saw off the aging branches and re-cultivate the main branches. Alternatively, long branches can be used instead of the main branches to form a new crown to restore its vigor and form a strong fruiting tree. The wound caused by trimming should be applied with a callus anticorrosive film in time to protect the growth of wound healing tissue and prevent infection of the wound from the wound. Antifreeze. Most of the chestnut tree leaves fall as soon as winter, especially in cold areas, chestnut trees are susceptible to freezing damage, which is very unfavorable for the winter of the tree. Before the chestnut tree leaves deciduous or frost, the general of the tree tray is loosened with grass and sprayed to protect the tree, and the water is poured in time to improve the cold resistance of the tree and make it safe for winter.
