Greenhouse Insulation: energy consumption is a major obstacle to the greenhouse warming winter runs. Improve the insulation properties of yin and yang greenhouse vegetable greenhouses project to reduce energy consumption of yin and yang vegetable greenhouse construction company, is the most direct means to improve the production efficiency of the greenhouse. Greenhouse insulation ratio is a basic measure of greenhouse insulation properties. Greenhouse insulation resistance ratio refers to a smaller greenhouse translucent material covering the area with a large greenhouse thermal envelope with the land area of ??coverage and the ratio. Insulation than the bigger, the better explanation greenhouse insulation properties. The formation of greenhouse gases and toxic precautions: winter heating temperature, if incomplete combustion of fuel will produce toxic gases, ventilation is not timely make excessive accumulation of carbon dioxide. Vegetable production. Precautions: ventilation. In Qingnuan weather, should be combined to adjust the temperature for ventilation, rain and snow should also be appropriate for ventilation. Choice of safe non-toxic plastic sheeting and plastic film, the timely removal of waste plastic materials and residues shed.
