According to investigations and analysis, apple orchards are not suitable for crops such as alfalfa, celery, aquatic plants, flax, wheat, potato, ramie, cotton, and tomatoes, because these crops compete with fruit trees for water and fertilizer, resulting in serious diseases and pests, which affect the robust growth of fruit trees and result in reduced yields. 1. Poria, celery, aquatic plants, flax. Planting grasshoppers, celery, aquatic plants, and flax between the apple orchards cause antagonistic effects with apples, competition with fruit trees for water and fertilizer, and pest and rodent breeding and spreading. Root secretions also inhibit the growth of fruit trees, so it is not appropriate to intercrop these four crops. 2. Wheat, potatoes, castor. Wheat, potato, and ramie are the hosts of the apple spider mites, and spider mites transfer to the apple tree to suck the leaf juice, causing the fruit trees to fall and fall. 3. Cotton, tomatoes. Intercropping with cotton, tomatoes, and apple trees, cotton bollworms are serious.
