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 a role in thermal insulation is wholesale, but the drawback is bulky insulation was Volume put a lot of work, effort, after being soaked in the rain and snow, both to increase the weight, but also make the insulation performance degradation, and pollution of the film, easily 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 is electric insulation, under the same conditions than the grass thatch covering temperature can be increased by 10 degrees for easy storage Collection This product is suitable for greenhouse, Greenhouse, eco-restaurant, long-distance trucks, greenhouses and other insulation cover, grass thatch and paper is the best alternative. Strengthen management. 1) vegetable greenhouse production management process must strengthen the management of light cold insulation is in favor of holding the premise covering mortgage as soon as possible, common light. 2). Adding carbon dioxide. Application of carbon dioxide fertilization, increased levels of carbon dioxide, but also help enhance the plant's resistance to cold. 3) It should be noted vegetable blight, gray mold incidence and spread.
