The specific operation method is as follows: pull the grass for about an hour in the morning, and let the wind release for 15 to 20 minutes. At this time, the tuyere should be opened slightly, about 10 to 15 cm wide, in order to remove the accumulated moisture for a night, and at the same time to supplement the carbon dioxide content in the shed. Because the outdoor temperature in the morning shed is very low, the air vent should not be opened too much, and the air release time should not be too long, so as to avoid excessive temperature drop in the shed and slow recovery. When the temperature in the shed rises to 28 ° C ~ 30 ° C, the air outlet can be pulled out to release air. The tuyere should be gradually opened from small to large, so that the indoor temperature of the shed is controlled at about 30 °C, which is conducive to the good growth of the plant. In the afternoon, the indoor temperature will gradually decrease. At this time, the small air inlet should be gradually closed to keep the temperature at around 25 °C; when the indoor temperature is lower than 22 °C, the air outlet should be completely closed.

Cabbage vegetables pay attention to the wind
In order to strive for spring vegetables in the morning, high yield and good efficiency, it is a prerequisite for the vegetable farmers to do temperature management: the temperature in the spring keeps rising, but it is still necessary to pay attention to the invasion of cold air, and the greenhouse vegetables are well regulated by temperature and humidity. The management method of “Daily Sanfeng†can not only reduce the indoor humidity, increase the carbon dioxide content, promote photosynthesis, but also increase the yield and increase the plant resistance.
