1. Do a good job of heat preservation, insist on opening the grass cover in the morning and night, and close the air vent in time to ensure the proper temperature for plant growth. 2. Strengthen the insulation and warming measures in the nursery greenhouse, take care of the seedlings to be planted in the near future, and prevent aging. 3. Discharge aerosols such as chlorothalonil, humilis, and azoxystrobin in sunlight greenhouses to prevent diseases, increase temperature and reduce humidity. In the evening, after the grass is covered, the smoke is ignited. The dosage is 200 grams per mu. When in use, place the aerosol evenly on the aisle at the rear of the greenhouse, and light it in turn from the inside to the outside, and enter the shed after 2 hours of ventilation the next day. 4. In the snowy or cloudy day, the grasshoppers should be opened to allow the vegetables to receive scattered light. On a snowy day, let the snow fall directly on the shed film to prevent the snow from falling on the grass to increase the weight and cause the shed to collapse.
