First, peeling. In early spring, a layer of plastic film is laid underneath the vine, and then the skin on the vine is stripped off to make it fall on the film. At the same time, pests and branches are cut off and the dandruff on the film is collected together and burned outside the garden.

Second, deep plowing. Combined with the application of grape sprout fertilizer, a deep ploughing of the entire garden, the depth of about 25 cm is appropriate. In this way, bacteria on the surface of the earth can be turned into the ground, thus reducing the incidence of pests and diseases and the chance of infection.
Third, chemical control.
1, pre-emergence prevention. In early spring, 7 to 10 days before the sprouting of the grapes, a complete garden disinfection with 0.3% sodium pentachlorophenolate plus 5 Baume's lime sulfur was performed to eliminate pathogens in the garden and reduce the incidence of diseases.
2, post-emergent control. After the budding of the grape, 0.5 to 1:200-fold Bordeaux mixture is sprayed once every 12 days to effectively control the occurrence of grape powdery mildew, black bean disease, black mold, and rot.
