Cultivation method for improving disease resistance of vegetables

The invention discloses a cultivation method for improving disease resistance of vegetables, and belongs to the technical field of vegetable cultivation. A cultivation method for improving disease resistance of vegetables comprises the following steps: S1, seed selection: selecting full vegetable seeds for cultivation, selecting disease-free seeds from seeds harvested in each season, planting and screening the seeds in different planting fields, and finally obtaining required to-be-planted seeds. According to the method, screening is conducted before vegetable seeds are planted, and the disease resistance of vegetables in the growth process is improved in cooperation with chemicals in the subsequent planting process; existing vegetable seeds are sequentially planted in planting fields where vegetables are not planted, vegetables are planted and similar vegetables are planted, the vegetable seeds can be gradually screened from common disease resistance to targeted disease resistance, and planting screening can
