Autumn is the most important season for the formation of flower buds in pear trees, and it is the key period for cultivating the result branches and fruiting branches in the second year. Therefore, strengthening the autumn management of pear trees plays an important role in pear production. Feng Leixiu, an expert in pears at the Northwest A&F University, believes that the management of pears in autumn includes pruning, fertilizer and water management, and pest and disease control. She hopes that the farmers will strengthen management according to quality and quantity, and lay the foundation for the production of excellent products and high yields next year. Pruning 1. Lazhizhizhi can help the young tree to form the crown early, prompt the pear tree to shoot early and increase the shoots, inhibit the vegetative growth of the tree, turn into reproductive growth as soon as possible, and finally achieve the purpose of early knot and high yield, pull the branch can be in the pear tree. After the end of autumn leaves fall to the second year before the spring sprout, generally 2-3 years old pear trees mainly pull the main branch or the main branch extension branches, vice main branch, etc., 4-5 years old trees are mainly pulled the vice main branch. Extension branches, lateral branches, second main branch. Due to the softness of the autumn shoots, they are not easily broken and set fast. The branches should be flattened or headed downwards. 2. Hanging branches and branches are soft, and in the fruit-rich period, the fruit branches are mostly sagging, and they are easily cleaved if the result is excessive. Can be tied in the long hair, the results of the pear branches with a rope hanging on the gills to prevent chapped. Long wooden poles with rakes can also be used to prop up the pear branch in the middle to prevent lychee from being overweight. Fertilizer management In the autumn and late fall of pear trees, it is generally advisable to use base fertilizers for pears in the middle or late September. It should be late as soon as possible, and it should be completed before the land is frozen. Fertilizer selection mainly includes farmer's fertilizer with many organic substances. This is the basic fertilizer for long-term supply of many nutrients in pears. Organic fertilizers are decomposed slowly and have long fertilizer effect. Pear tree roots are sparse and their fertilizer performance is slow. Nitrogen fertilizer, phosphate fertilizer and potash fertilizer, less nitrogen fertilizer, more potassium fertilizer. General age pear trees per plant 50 to 100 kg of organic fertilizer, superphosphate 5 to 10 kg, ammonium nitrate 1 to 2 kg, fertilization depth 25-35 cm. After fertilization with water source conditions, it is necessary to pour 1 or 2 times permeated water, which can not only allow the fertilizer to have sufficient moisture to rapidly rot, ferment and decompose, but also prevent autumn drought. Before the soil is frozen after defoliation, the entire garden is filled with winter water to facilitate the safe wintering of trees. Pest Control Pear bark is a wintering ground for many kinds of pests. Pyrosphaeridae, P. striata, P. gracilis, P. gracilis, P. gracilis, P. crassifolia, etc. are often overwinter in bark cracks, and become the source of diseases and insect pests in the following year. The old skin of the pear tree lacks of lateness, which restricts the bold growth of the tree body. Therefore, the old skin should be scraped off in the autumn to reduce the base number of wintering of the disease and pest, so as to lay a solid foundation for the prevention and control of pests in the coming year. It was burned in time, and the main branch was painted white with whitening agent such as quicklime, salt, sulfur powder, water, etc., and Bordeaux liquid was sprayed in full to better exert the effect of scraping. At the same time, according to the occurrence of pests, spray 50% of carbendazim WP 500 to 600 times or 70% thiophanate-methyl for every 15 to 20 days in the pear orchard harmful to ringworm, scab, and mold. 800 times fluid to control the condition. Feng Yuexiu said that after falling leaves, it is necessary to promptly clean up fallen leaves and dry branches in the orchard, eradicate weeds, and burn them together. After the hanging sticks and top sticks are used, they should be burned in time. Before the soil is frozen, it is best to The garden is deep-turned to a depth of more than 30 cm to ripen the soil and promote root growth.
