Embodiment Construction

[0010] 1. Fertilize in balance. The base fertilizer should be fully decomposed organic fertilizer, phosphorus and potassium fertilizer should be added in top dressing, the amount of nitrogen fertilizer should be controlled, and some foliar fertilizer and micro-fertilizer should be sprayed as much as possible to enhance the resistance of plants. 2. Cool down and dehumidify. During the day, the temperature is controlled at 15°C to 20°C. When it exceeds 20°C, it is necessary to release the wind in time. At night, it is controlled at 10°C to 15°C to reduce the worst day and night, reduce condensation, and do not flood with water.

[0011] 3. Chemical control. Use 45% chlorothalonil or promethazine to fumigate the shed, 150 grams per mu, scatter 5 to 6 places and ignite, fumigate overnight, once every 10 days or so. Spray 70% mancozeb wettable powder 600 times liquid or 50% carbendazim wettable powder 600-800 times liquid at the early stage of the disease, once every 7-10 days,...
