Digging maggots and moths are based on the habits of peach borers and zao ziqus focusing on wintering in the soil around the trunk, combined with soil deep turning, picking overwintering insect pests and insect pests before and after the soil is frozen and thawing. Reduce the number of insect populations in the coming year.
Scraping the old skin and scraping old skin can not only eliminate pests but also stimulate the growth of trees. The time for scraping the skin is usually after defoliation and before germination, and a plastic sheet is placed under the tree to collect the bark and insects, which are then burned or buried deeply.
The tree trunk is painted white and white, which can prevent cold and prevent disease. Formulation of whitening agent: 12 parts of quicklime (open with cold water), 2 parts of sulfur or 3 parts of lime sulfur stock solution, 2 parts of salt (opened with hot water), 36 parts of water, proper amount of glue, lime and sulfur can be used to prevent freezing Anti-sunburn can also prevent disease and kill insects.
Cut worms and worms combined with pruning in winter, cut off the larvae damaged by the larvae, and for serious branch damage, use wire brush to get rid of their overwintering worms, and also pay attention to cut off the overwintering larvae of the larvae.
Spraying chemicals Because of the waxy shell on the surface of turtle wax, general chemical pesticides are hard to kill and can be sprayed with diesel emulsions to eliminate them. Before the jujube sprouts, the entire tree should be sprayed evenly and thoroughly with Baume 5 degree lime sulfur, which can control the red spider, pear orchard and other pests.
