How to choose greenhouse?

Plant growth needs light and temperature, the initial role of the greenhouse is to heat preservation, heat preservation is to ensure the normal operation of the greenhouse in winter essential conditions, improve the greenhouse thermal insulation performance, reduce energy consumption, is to improve the greenhouse production efficiency of the most direct means. The main index to measure the thermal insulation performance of the greenhouse is the thermal resistance of the greenhouse envelope.

(3) Look at the durability

Some greenhouses can not be used in five years, some greenhouses will not be damaged in ten years, the value is definitely different, that is to say the durability of the greenhouse. The durability of the greenhouse mainly depends on the aging resistance of the greenhouse materials and the bearing capacity of the main structure of the greenhouse. The bearing capacity of the main structure of the design greenhouse is directly related to the reappearance of the maximum wind and snow load. Generally, the service life of steel structure greenhouse is more than 15 years, and the design of wind and snow load is once in 25 years. The simple greenhouse with bamboo and wood structure has a service life of 5 to 10 years, and the maximum load designed for snow and wind is once in 15 years.

(4) Look at the applicability

The applicability of greenhouse refers to the ability of greenhouse to meet the function and realize the function, which is the most important aspect to evaluate the structural performance of greenhouse. Such as greenhouse space size, greenhouse environmental parameters (daylighting, temperature, humidity, etc.), supporting facilities (heating facilities, shading and insulation system, water supply system, transmission mechanism, electrical equipment, control equipment, etc.).

(5) Look at the price and disaster prevention ability

It's very good, but the investment is too big. We growers may not be able to afford it. We will have to see the price eventually. Greenhouses cost money to build, and they also cost money to run and maintain. Operation and maintenance should consider the disaster prevention capacity of the greenhouse, originally the performance of the greenhouse is good, but in the case of accidents such as earthquakes, tornadoes, is it able to bear, although the possibility is small to be taken into account.
