Light transmittance Greenhouse is a light construction, transmittance is thus one of the most basic indicators of evaluating greenhouse. Transmittance refers to the amount of light penetration into the greenhouse for the percentage of outdoor illumination. Greenhouse light transmittance transmittance of greenhouse covering materials and the rate of greenhouse shading effects, and with different angles of solar radiation in different seasons, light transmittance of greenhouse are also subject to change. Greenhouse crop growth rate height becomes directly influencing factors and selecting crop varieties. In General, 50%~60% of multi-span plastic greenhouse, glass light transmittance of greenhouse 60%~70%, greenhouse could reach more than 70%. Insulation Major obstacle to the operation of heating energy consumption is greenhouse in winter. Improve insulation, reducing energy consumption, is the most direct means of improving the efficiency of greenhouse production. Greenhouse insulation ratio is a basic indicator for measuring greenhouse insulation. Greenhouse the greenhouse heat less refers to thermal resistance than larger coverage area and thermal resistance of the material covered greenhouse enclosure area with an area of more than. Insulation greater than, indicating greenhouse heat preservation performance is good. Durability Greenhouse construction must take into account its durability. Durability of greenhouse greenhouse material aging resistance, greenhouse influence of the carrying capacity of the main structure. Durability of transparent materials in addition to its own strength, but is also reflected in the transmitted light along with the decay time and materials, and attenuation of light transmission rate is a critical factor affecting the service life of translucent material. Greenhouse steel structure use life of 15 years or more. Demanding design wind and snow loads in 25 years at maximum load, bamboo wood frame simple greenhouse life 5-10, wind and snow load with a 15-year maximum load. Due to long-term greenhouse operation at high temperature and high humidity environment, component%9
