Cut and scrape. In winter, it is a good time for pruning Chinese pepper. When trimming, it is necessary to cut leggy branches, dry and dead branches, disease and insect branches, over dense branches, cross branches, overlapping branches, and delicate branches. Trimming wounds should be promptly painted and protected by anti-corrosion film. Scrape is to scrape rough skin. There are many eggs parasitizing in the cracks of the pepper tree, and Mulberry is parasitic on the trunk. The rough and fluid spots that have been scraped off are burned and burned. Then the generals are wiped and wiped, and the pathogens are infested from the wound.

Coated and sprayed. Tu is painted white on the trunk. Whitening can reduce frost damage, delay germination and flowering of pepper trees, and protect pepper trees from the harm of spring frost. Spray is spray pesticide. Some germs and eggs, except for wintering on litter and weeds, can also be parasitized over winter at tree shrews and other sites. Therefore, before the pepper tree sprouts, it is generally sprayed once to protect the tree generals and insecticides. It is better to spray medicine when the pepper leaves are not falling, and the control effect is excellent. At the same time, other trees around the garden should be sprayed to prevent the spread of pests and diseases.

Shi He turned. Shi is changing soil and fertilizing. Peel old roots of prickly ash tree roots and cut roots. Sprinkle the roots and disperse the roots and roots, and then replace them with new soil to prevent root rot. Then, under the canopy of the prickly ash, ring-shaped, radial, and strip-shaped fertilization methods were applied to farmyard manure, phosphate fertilizer, and potash fertilizer, and appropriate nitrogen fertilizer was applied. Turning is turning over the pepper garden. Using the natural conditions of low temperature and drought in winter, through overturning the garden, the overwintering pests in the soil are thawed out or eaten by birds.

Pour and clear. Pouring is winter watering. After entering the "Thirty-nine" season, pouring sufficient water for winter peppers can provide warm winter weather, increase nutrition, and increase the resistance of the tree. Qing is the Qingyuan Garden. Some of the pepper tree's germs and eggs parasitize on dead leaves and winter. In the winter, you can clean up the debris in the garden before turning the garden, and burn them in a concentrated manner to eliminate the wintering germs and eggs.
