If the protection is not proper, after the rainwater is irrigated, the water in the shed should be quickly drained. When the soil sees dryness, it should be ploughed in time, loosen the soil and increase its permeability to prevent rooting or root disease.
2. Pruning vines in time to improve the permeability between plants
When the pruning is not timely, the plants are shaded by each other, which is easy to cause the field to be closed, and the stems are also prone to produce adventitious roots. Therefore, it is recommended to pruning the vines in the sunny weather. After the vegetable pruning is completed, spray a fungicide to prevent the pathogen from invading the wound.
3, pay attention to balanced nutrition
Appropriate fruit thinning, reduce nutrient consumption, and facilitate balanced nutrition distribution. At the same time, before the rainy weather arrives, it is recommended to apply functional fertilizers to increase root activity and increase nutrient absorption capacity.
