In order to strive for spring vegetables for the morning market, high yield, and good efficiency, it is a precondition to ask the vegetable farmers to do a good job in temperature management: the temperature in spring continues to rise, but we must pay attention to the invasion of cold air, and regulate the temperature and humidity of greenhouse vegetables so as to achieve a The "three-day ventilation" management method can not only reduce the humidity in the greenhouse, increase the carbon dioxide content, promote photosynthesis, but also increase the yield and increase plant resistance. The specific operation method is as follows: In the morning, the grasshopper is pulled open for about one hour, and the air is released for 15 to 20 minutes. At this time, the tuyere should be smaller, about 10 to 15 centimeters wide. The purpose is to remove accumulated moisture from the night and supplement the content of carbon dioxide in the booth. Because the outdoor temperature of the morning shed is very low, the tuyere should not be opened too large, 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 room temperature rises to 28°C to 30°C, the air outlet can be pulled open. The tuyere should be gradually opened from small to large, so that the greenhouse temperature is controlled at about 30 °C, which is conducive to the growth of plants. In the afternoon, the indoor temperature of the shed will gradually decrease. At this time, the small air inlet should be gradually closed to keep the temperature at 25°C. When the temperature in the shed is lower than 22°C, the air outlet must be completely closed. 30 °C ~ 25 °C is a suitable temperature to ensure the growth of vegetables, so the management of the greenhouse should try to maintain this condition, give plants a comfortable environment. About half an hour before the release of the afternoon, the small air outlet was ventilated for 15 minutes in order to discharge the moisture in the shed, and at the same time, replenish some fresh air, which was conducive to the growth of the vegetable plants at night. When the temperature in the shed is around 20°C, the grasshopper should be put down to ensure that the plants grow at night without cold damage. Special Weather Uncovering Grass and Grass Method: 1. Warm weather in March-April, try to cover the cover as soon as possible, and remove it before and after the rainy season. 2, rainy weather - try to expose the light during the day, and can not be exposed for a few days. 3, Lianyinqing - can take "exposing cover", with the recovery measures, and gradually transferred to normal management. Found wilting, can spray clean water emergency.
