Applying base fertilizer around September When there is more rain in autumn, only weeding is not loose. Combine the application of base fertilizer and irrigation before and after defoliation, and carry out cultivating loose soil. The depth is about 25 cm, close to the dry circumference, about 10 cm, so as not to hurt the thick roots, gradually deepening from the inside to the outside. In the autumn ploughing, the soil is properly cultivated on the trunk to protect the roots from safe wintering and reduce the damage caused by freezing. Protecting the roots and necks of peach trees, preventing low-lying dryness and preventing the accumulation of water at the roots is an important measure to ensure the healthy growth of peach trees and high yield and quality. In the autumn, the base fertilizer is earlier than the spring application, and the flowering rate is high. The base fertilizer should be based on organic fertilizer and added with appropriate fertilizer; the fertilizer is mainly nitrogen, phosphorus and potassium, and adding appropriate amount of trace elements. The amount of base fertilizer applied should account for 60%-70% of the total fertilization in the whole year. The adult tree is based on the fruit yield and the main growth of the tree. According to the production of 100 kg of peach fruit, about 200 kg of organic fertilizer, 0.7 kg of available nitrogen, 0.5 kg of phosphorus and 1.0 kg of potassium are calculated. Newly planted young trees should focus on applying organic fertilizer, with little or no nitrogen fertilizer, and fertilization is based on the principle of not stimulating young trees. For varieties, early-maturing varieties can be applied with less nitrogen; those with strong erectile tend to be weaker and less likely to apply less nitrogen. Old trees, weak trees should appropriately increase the amount of nitrogen fertilizer applied. The best period for the autumn application of the base fertilizer is around September, and it can also be combined with autumn tillage before and after the fall leaves. The fertilization method is applied by radiation ditch or annular ditch, and the depth reaches the main root distribution layer. When the root system of dryland in the mountainous area is shallow, it is applied to a depth of 20-40 cm, and the plain soil is applied to a depth of 30-50 cm. When fertilizing and digging pits, the topsoil and the heart soil should be placed separately. The fertilizer should be mixed with the topsoil and filled into the bottom of the pit, and the old soil should be on the surface. In recent years, experienced fruit farmers have achieved remarkable results after collecting fruit with a large amount of trees, 10-15 days, and spraying 2-4 times of concentration of 0.3%-0.5% potassium dihydrogen phosphate. In order to ensure the water supply of the peach trees during the winter, it is necessary to fill the frozen water in the early winter from the end of October to the middle and late November after the application of the base fertilizer, and the water should be wetted through the dry soil layer. If there is more autumn rain, the soil is good, and the soil is more sticky. It can be lightly irrigated or free of irrigation. After irrigation, it should be loosened to prevent freezing.
