Greenhouse construction is light construction, so construction need to have good light effect when greenhouse construction, light transmission rate is a basic indicator light transmission properties of greenhouse evaluation. Greenhouse construction transmittance by the greenhouse effect translucent cover professional greenhouse construction, greenhouse construction materials and light transmission rate of greenhouse skeleton shadows in different seasons and with the angle of the solar radiation transmittance different, greenhouse construction also subject to change. Therefore, the light transmittance is a key factor in greenhouse crop growth. 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 and a length of 45-66 meters greenhouse construction, covers an area of ??about 660 square meters, greenhouse construction manageable favorable production. Or pent roof shed connected together. Construction of single-span greenhouse Dong of 4-12 meters, building greenhouses Each area is about 1 acre greenhouse construction cost, multi-span covering after 2-5 acres, or 10 acres, dozens of acres. Of Greenhouse cover a large area, land use fully, the greenhouse temperature high, temperature stability, cushioning and strong, but poorly ventilated greenhouse construction technology, 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.
