Greenhouse construction materials covered are the following: 1. Ordinary film. Polyethylene or polyvinyl chloride as raw vegetable greenhouse construction, the thickness of 0.1 mm, colorless and transparent. Life of about six months. 2. Multifunction longevity film. Greenhouse construction is adding an appropriate amount of polyethylene blow molding process and made anti-aging masterbatch surfactants. Greenhouse construction plastics factory currently produced wide (7.5 m) Multi-film thickness 0.06 mm solar greenhouse construction, twice the length of life than ordinary film night Pengwen be high 1 ~ 2 ℃, and the film surface is not easy to bear droplets. Therefore good coverage, low greenhouse greenhouse construction budget cost, high efficiency. 3. Grass, grass fan. Grass, grass fan is used at night insulation materials, woven straw, good thermal insulation. Greenhouse construction of the wall construction quality directly related to their length of life. Greenhouse shed construction is towards a higher, wider, no column in the direction of the wall which further requires greenhouse firmness stronger, better stability. North-south width of the bottom wall of the greenhouse construction are advised to use a bulldozer compaction, construction of the current high standard greenhouses pressed soil requires 6-8 meters, to prevent ground subsidence. Then the excavator on earth and every 50 cm of loose soil on the use of a bulldozer rolling back and forth at least three times. Greenhouse construction built back wall height of 4.5 meters is appropriate finally top of the wall with bulldozers compaction. Also Note excavators cut shed wall on the narrow width inclination to have a certain inclination to 6-10 degrees is appropriate and the wall should be flat.
