The greenhouse will not release itself within an hour after the curtains are opened.
Because after the grass cover was covered in the evening, the vegetables in the greenhouse stopped photosynthesis and only a large amount of carbon dioxide was released through the respiration. At the same time, the organic matter in the soil decomposed organic matter also released carbon dioxide. After the night, the carbon dioxide content accumulated in the shed increased significantly, much higher than the outside atmosphere. Carbon dioxide content. Therefore, the next morning, when the straw curtain was opened, the wind was not released and the vegetables began to undergo photosynthesis after receiving the light, fully absorbing the carbon dioxide in the greenhouse and converting it into organic substances stored in the fruit. 70%-80% of photosynthetic products in one day were synthesized in the morning. In the one hour before the release of the wind, the organic matter accumulated by the plants through photosynthesis will be several times as usual, and the yield of vegetables will be greatly increased.
Therefore, in the morning, the sun rises, and the straw curtain is opened. After an hour, the small mouth is released for 7-8 minutes, and then the ventilation is stopped. After the temperature in the shed has risen to a certain extent, see the actual situation and release the wind again. The main purpose of a small mouth is to reduce the temperature, the second is to eliminate humidity, and the third is to eliminate harmful gases. Correct air management is an effective method for high yield in greenhouses, which can greatly increase the output of vegetables and melons.
