Chinese herbal medicines should be applied to basic fertilizers in autumn and winter, mainly organic fertilizers, and phosphorus and potassium fertilizers should be added. Basal fertilizer uses 250,000 kilograms of fully-fertilized manure, 30 to 50 kilograms of compound fertilizer or phosphate fertilizer per acre, and deep-grooves between rows, which is beneficial to the growth of Chinese herbal medicines in the following year, and increase production. 1. Clearing the garden: In the autumn and winter, the garden must be cleared in time to remove the diseased plants and leaves, concentrate and burn deeply, reduce the number of overwintering pests and diseases, and disinfect the lime in the pest and disease area. The whole park is sprayed with lime sulfur to seal it. Park to eliminate overwintering pests. 2. Pruning: Pruning is an important increase in production and management of Chinese herbal medicines. After its fallen leaves, it is necessary to remove the branches and branches of the pests, thin and weak branches, trim the branches, and cultivate a high-yield tree. Larger cuts such as truncated cuts and shears can be made in the winter. 3. To prevent freezing injury: In the late growth period of Chinese herbal medicines, appropriate application of phosphorus and potassium fertilizers within one month prior to the frost fall, promote their full lignification, and enhance the cold resistance of the plants. Watering the day before frost can increase ground temperature and prevent frost. If the soil is too dry, pour water once before the soil freezes to prevent freezing. Before the onset of the cold wave, precious or plant-short Chinese herbal medicines can be covered with rice straw, wheat straw, etc., covering a thickness of about 5 cm; woody Chinese herbal medicines that are sensitive to cold can be bandaged and combined with rhizosphere soil to prevent freezing damage. After the Chinese herbal medicines are harmed by frost, they should take prompt remedial measures, such as assisting the seedlings, making up the seedlings, replanting or replanting, and strengthening field management. Frozen woody parts of woody Chinese herbal medicines should be cut off in time to promote new shoots to germinate and restore tree vigor.
