Good daylightingThe light transmittance of greenhouse is affected by the light transmittance of greenhouse covering materials and the shadow rate of greenhouse skeleton, and the light transmittance of greenhouse is also changing at any time with the different solar radiation angles in different seasons. The light transmittance of multi span plastic greenhouse is 50% ~ 60%, that of glass greenhouse is 60% ~ 70%, and that of solar greenhouse can reach more than 70%.

Strong wind and snow resistanceThe durability of greenhouse construction must be considered. The durability of greenhouse is affected by the aging resistance of greenhouse materials and the bearing capacity of the main structure of greenhouse. It is required that the maximum load of 25-year return period shall be used for the design wind and snow load; The service life of simple greenhouse with bamboo and wood structure is 5 ~ 10 years, and the maximum load with a return period of 15 years is used for the design wind and snow load.

Good thermal insulation and long service lifeHeating energy consumption is the main obstacle to the operation of greenhouse in winter. Improving the heat preservation performance of greenhouse and reducing energy consumption are the most direct means to improve the production efficiency of greenhouse. The heat preservation ratio of greenhouse is a basic index to measure the heat preservation performance of greenhouse. The larger the insulation ratio, the better the insulation performance of the greenhouse.
