Tightness. We should keep greenhouses tightness, only tightness reached in order to play the role of insulation, insulation covering material previously used straw thatch, Po seats, etc., although it can play the role of insulation, but the drawback is heavy, volume put a lot of work laborious, after being soaked in the rain and snow, both to increase the weight of the insulation was purpose, and so decrease the supply of thermal insulation performance is, but the film pollution, easy to reduce the transmission rate. The greenhouse insulation is a lightweight, waterproof, anti-aging, insulation, and other far-infrared reflectance function, long life, good insulation effect, under the same conditions than the grass thatch covering temperature can be increased by 10 degrees for easy storage collection, the product suitable for greenhouse, Greenhouse, eco-restaurant, long-distance trucks, greenhouses and other insulation cover, grass thatch and paper is the best alternative. Air humidity regulation: the greenhouse air humidity is too large industrial insulation was not only directly affects photosynthesis vegetables and mineral nutrient absorption insulation was, but also conducive to spore germination and infection. Therefore, the need for ventilation, promote shed humid air humidity air is exchanged with the outside world, can effectively reduce the relative humidity in the greenhouse. Hotline to shed heat, but also can reduce the relative humidity. Using drip irrigation technology, combined with mulching cultivation, reduce soil moisture evaporation, can greatly reduce the air humidity (about 20%). Insulation is wholesale | Henan insulation was | Canton St. agricultural machinery provided by Shouguang Agricultural Machinery Co. St. Canton.
