[0002] Crop cropping disease refers to the phenomenon that a certain crop is planted multiple times in the same field, resulting in low seedling emergence rate, low seedling survival rate, slow plant growth rate, and death in severe cases. The cropping disease is also called replanting disease. .Due to the special environment and repeated planting year after year, the replanting disease has become more and more serious, resulting in a substantial reduction in the yield of horticultural crops such as fields, protected areas, greenhouses or greenhouses (an average annual rate of more than 30%), and sometimes resulting in failure.
