Greenhouse performance indicators: greenhouse durability. General Steel Greenhouse life of more than 15 years. Designed wind, snow load with a maximum of 25 years in case of a load; bamboo structure greenhouse life of 5 to 10 years the price of plastic greenhouses, design wind, snow load with a maximum load of 15-year return. Due to long-term greenhouse operation in high temperature, high humidity environment greenhouses design, surface corrosion member becomes an important factor affecting the life of the greenhouse. The formation of greenhouse gases and toxic precautions: winter heating temperature, if incomplete combustion of fuel will produce toxic gases greenhouses, 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.
