1, according to the principle of suitable tree, choose adaptable, resistant varieties afforestation. Improve the site conditions, strengthen management and protection, enhance the tree vigor, and cure other pests and diseases at the same time so as to prevent the occurrence of large-scale decay diseases. 2, strengthen seedling management, cultivate seedlings, strong seedlings. Seedling quality is good or bad, is directly related to the occurrence of rot disease, cultivating seedlings, seedling is the key to prevent the occurrence of rot disease.
