Greenhouse major types: plastic greenhouse structure. Because of their light weight plastic greenhouse, resistance to wind, snow load is weak, so the overall stability of the structure must be fully considered, in general or in the interior of the second cross the bay to set the second vertical bracing, in the greenhouse the external structure and the roof space should also consider setting up the necessary support. Best supporting oblique (oblique rod) anchored in basic pig shed skeleton, a space force system. 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 mushroom greenhouse frame, 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 greenhouse frame manufacturing plant, should be established. But the slope can not be too large, the projected length of about one meter should be maintained to reduce shading. After the slope elevation reasonable greenhouse frame, around 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.
