Greenhouse construction arid region in northern China, a cold spell, deep permafrost, snow big, the use of the span, the height of the larger circle arch shed. In the form of a variety of greenhouse construction. Greenhouse construction which has the form of single-span arch shed and two round-shaped roof. Height 2.2-2.6 m, width (span) 10-15 meters, 45-66 meters in length, covers an area of ??about 660 square meters greenhouse construction requirements, greenhouse construction manageable favorable production. Or pent roof shed connected together. Span greenhouse construction of single-family building 4-12 meter greenhouse manufacturers, greenhouse construction Each area of ??about 1 acre, multi-span after covering 2-5 acres, or 10 acres, dozens of acres. Of Greenhouse cover a large area, land use fully, the greenhouse temperature high greenhouse greenhouse construction budget, temperature stability, cushioning and strong, but poorly ventilated, often resulting in the greenhouse temperature, high humidity conditions endanger or cause disease occurrence, and management inconvenience. Therefore, the number of multi-span should not be too much, not too much span. Greenhouse construction materials covered are the following: 1. Ordinary film. Polyethylene or polyvinyl chloride as raw materials, a thickness of 0.1 mm, a 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 greenhouse construction, 0.06 mm thick, double the service life longer than ordinary film night Pengwen be high 1 ~ 2 ℃, and the membrane surface is hard to form droplets . Therefore good coverage, low cost, high efficiency. 3. Grass, grass fan. Grass, grass fan is used at night insulation materials, woven straw, good thermal insulation.
