The plastic film can effectively prevent carbon dioxide generated in the growth process of vegetables from losing so as to achieve the heat preservation effect required in the greenhouse.
In the process of planting greenhouse vegetables, because the interior of the greenhouse is closed, harmful substances are easy to generate, and the growth speed of the vegetables is damaged. Therefore, the air pressure should be properly controlled and properly applied. When the temperature is higher in the noon, the ventilation opening is properly opened to ventilate, so that harmful gas is prevented from damaging vegetables. The greenhouse vegetable selected for planting is mainly in a temperature preference type, the optimal temperature is 25-33 ℃, the highest temperature for survival cannot exceed 44 ℃, and the lowest temperature cannot be below 0 ℃. When the temperature exceeds 33 ℃, the temperature is reduced by adopting regular shed-opening ventilation, ventilation holes, spraying and the like. When the temperature is lower than 0 ℃, heating treatment is performed, such as hot air heating. The humidity in the greenhouse is controlled, and the phenomenon that the growth of vegetables is influenced by overlarge humidity is avoided. Therefore, frequent ventilation is required to improve the humidity in the greenhouse.
