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 and other agricultural holding is, although it can play the role of insulation, but the drawback is heavy, volume put a lot of work, effort, after being soaked in the rain and snow, not only increasing the weight of the insulation was, and so was the wholesale thermal 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 dishes insulation was shed, 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 is suitable for greenhouse, Greenhouse, eco-restaurant, long-distance trucks, greenhouses and other insulation cover, grass thatch and paper is the best alternative. Spring planting cultivars large peel: fruit weight 15-20 kg, 3000-4500 kg per mu; Hunan base after rushing Melon: fruit weight 40-50 kg per mu 5000-10000 kg; Jufeng 1: fruit weight 40 -50 kg, about 6000-10000 kg per mu; Black melon: fruit weighs about 13-15 kilograms per mu 3000-3500 kg; Dongguan black melon: fruit weighs about 10-15 kilograms per mu, about 3000-3500 kg; precocious pink Miscellaneous: fruit weight 13-20 kg, more than 5000 kg per mu.
