Greenhouse performance indicators: greenhouse durability. Greenhouse impact of greenhouse material durability anti-aging properties, the carrying capacity of the main structure of the greenhouse and other factors. Durable translucent material addition to its own strength, but also in the material light transmittance with time constant attenuation film greenhouses construction prices, and the degree of attenuation of the light transmittance is the decisive factor in the life of translucent material impact. The formation of toxic greenhouse gases as well as preventive measures: ethylene and chlorine if the quality of plastic sheeting or film is poor, there are residual within film, the film greenhouses designed to direct sunlight, high temperature conditions at the studio, volatile harmful or ethylene and chlorine, etc. gas. When the concentration reaches a certain time, can turn yellow between the veins vegetables margin or film greenhouses built, then white, whole plant dead serious. Often misdiagnosed as bacterial angular leaf spot, cucumber particularly serious harm.
