Appropriately sparsely planted and strictly pruned: Plants that are properly sparse and can not be allowed to take their natural branches as in open cultivation must be artificially pruned. Strict pruning can generally adopt the method of double dry pruning. In the early stage, the plants can be interlaced 2 dry, interlaced 3 dry, until 3 dry affect the light transmission between the lines, and then resolutely restored to 2 dry pruning. Enhance the immunity of plants: timely kill the yellowing of the lower leaves. The general tree guard was sprayed in a timely manner to control the breeding and spreading of airborne viruses, to protect the plant tree's self-defense reaction instincts, to destroy harmful bacteria supply sources, to infiltrate the elimination of viruses, and to close the virus replication and transmission pathway. Prevent damage to sub-healthy plants caused by bad weather (frost, explosion, hail, and rain). Reduce disease recurrence and reactivation rate, improve plant growth and fruit growth health index. Clean the film regularly: Keep light transmittance as high as possible.
