The light curtain, carbon dioxide gas fertilizer and aerosol test were conducted in a solar greenhouse, and good results were obtained. Application of reflective screen According to experimental observation, the distribution of light and temperature in the greenhouse is uneven, with strong light in the middle of the greenhouse, high gas and ground temperature, weak light before and after the greenhouse, low gas and ground temperatures, and low vegetable output. The light curtain (which is a kind of aluminized polyester film with high reflectivity) is hung on the back of the greenhouse, which can change the light distribution in the greenhouse and increase the light intensity at the low light in the rear, so that the light in the greenhouse The temperature distribution is relatively uniform, generally increasing the yield of vegetables by 10% to 20%. The application of carbon dioxide gas fertilizer Solar greenhouse in a cold winter, long sealing time, less ventilation, easy to make greenhouse vegetables in photosynthesis of carbon dioxide raw material serious lack. In particular, after 1h of sunrise, the concentration dropped, causing the vegetables to be in a state of severe hunger. In the long term, the plants grow weak, prone to premature aging, and the yield is low. Therefore, the regular application of carbon dioxide gas in the greenhouse can generally increase production by more than 20%. Application of Aerosols Due to the high humidity in the solar greenhouse, it is easy to send all kinds of fungal diseases. Such as spraying with water spray, the effect is often not good, and use of smoke for smoke prevention and disease prevention, because it will not increase the humidity inside the shed, and the drug distribution is even, so the control effect is ideal.
