Winter chestnut management technology
In order to produce high yields of chestnuts in a row, it is necessary to break the practice of picking chestnuts only, especially the chestnut trees in the fruiting period. It is necessary to do a good job of management after harvesting; otherwise it will affect the yield and quality of the chestnuts in the following year. The following is a brief introduction to the management techniques of winter chestnut. Fertilization. Generally, organic fertilizer is mainly applied, and a small amount of chemical fertilizer is applied. Fertilization combined with root application and root cultivating after root irrigation, in order to facilitate root absorption, and quickly restore the tree potential. Scratch the skin. If the tree is over 10 years old, it can be scraped, and the time of scraping should be the best after picking the fruit. For cold areas, it is generally suitable to scrape the skin in early spring. The trunk and the main skin of the fruit tree are the places where the pests overwinter. When scraping the skin, the plastic should be placed under the trunk, and the rough skin, old skin and skin should be scraped off with a sharp knife, and brought to the outside of the garden to be burned. After scraping the skin, the trunk and the big branches are painted in time to protect the tree generals and whitening agents to prevent pests or germs from infecting the trunk. prune. After the pruning and shaping of the 5-6 year old chestnut tree, only the roots and the lower branches and the lower branches are cut off, and the dried branches, dead branches and diseased branches are all cut off. For crowded overlapping branches and dense branches in adult trees and old trees, the overlapping branches and dense branches of the inner scorpion should be appropriately removed to promote the ventilation and light transmission of the canopy, and the stereoscopic result. For the aging chestnut tree, it is necessary to cut off the aging branches and re-cultivate the main branches. It is also possible to replace the main branches with long branches, to form a new canopy, to restore the tree potential and form a strong fruit tree. The wound caused by trimming should be applied to the wounded anti-corrosion film in time to protect the wound from healing tissue growth and prevent infection from wounds. Antifreeze. Most of the chestnut trees fall in the winter, especially in the cold regions, the chestnut trees are vulnerable to freezing damage, which is very unfavorable for the wintering of the trees. Before the leaves or frosts of the chestnut trees, the trees should be loosely sown and the trees should be sprayed to protect the trees. The generals should be kept warm in time to improve the cold resistance of the trees and make them safe for winter. Disclaimer: Some articles on this website are transferred from the Internet.
