The main types of greenhouses: Greenhouse performance. Energy-saving solar greenhouse transmittance is generally more than 60% to 80%, indoor and outdoor temperature difference can be maintained at more than 21 ~ 25 ℃. Greenhouse lighting. On the one hand the solar radiation is to maintain or keep Greenhouse temperature heat balance of the most important energy source; on the other hand modern greenhouses, solar radiation is the only source of crop photosynthesis. After Greenhouse slope angle and projected length: After slope increase greenhouse temperature and altitude, increasing the lighting face angle, which will help the sun injection. But the slope north of the scattered light into the barrier, the deterioration of the rear light, causing the rear greenhouse crop growth, yield and quality significantly inferior to the front of the crops. Balance the pros and cons, and for ease of placement and Uncovery insulation covering the construction of new greenhouses prices, should be established. But the slope can not be too large new greenhouse project, the projected length of about one meter should be maintained to reduce shading. After a reasonable slope elevation, about 36 degrees north latitude regions, remain above 38 degrees for easy cold season, after the inner wall of the slope of direct sunlight, which will help improve the greenhouse temperature and lighting conditions to improve the rear of the greenhouse.
