Persist in unveiling the curtains even at noon, as long as the temperature is not lowered after the draft curtains are unveiled, the straw curtains should be unveiled. This can promote plants to receive scattered light, increase the plant's ability to adapt to light, and help increase yield. Appropriate heating, even on cloudy days, should not be too hot for the strawberries in the facility, especially at night. Because the night temperature is high, breathing is strong and consumes a lot, and even if the curtain is opened during the day, there are not many nutrients produced, which can not stand up at night. Heating is generally performed at night and short-term ventilation is performed around noon. To reduce the humidity, the front edge of the greenhouse shall be provided with a waterproof trench, and a mulch film shall be laid at the bottom of the trench to drain the water flowing out of the membrane out of the shed or perforated into the ground. The timely control of the relative humidity of the air in the shed below 85% can effectively control the germination of most fungal spores, thereby controlling the occurrence and infection of strawberry fungal diseases.
