Farmers in the construction of vegetable greenhouses to combine the types of crops and local climate conditions to complete the design and construction work, and the quality of greenhouses and many factors. First of all, there is a direct relationship between the quality of canopy construction and light transmittance. When planting crops, plants need to undergo photosynthesis in order to grow smoothly, if the farmers in the process of building greenhouses without such transparent requirements, then it will affect the growth of crops, and directly affect the yield. And the light transmittance of the greenhouse is not invariable either. Combined with the different seasons, the light conditions in the same area will be different. Therefore, in order to ensure that the light transmittance of the greenhouse meets the standard requirements, the general farmer friend pays attention to choose the suitable material to build the big shed.

　　In addition, the warmth retention of vegetable greenhouses is also very important, especially in areas with relatively low temperatures, when building greenhouses, we should pay attention to whether the temperature of the greenhouses can meet the requirements for crop growth, but the greenhouse temperature standard actually and the greenhouse cover area as well as the material thickness has the very big relations. In the construction of vegetable greenhouses, it is necessary to select durable materials for construction. Through the above introduction, we can see that the covering materials chosen for greenhouses have a great impact on the transparency and thermal insulation of greenhouses, and the choice of other materials in the construction of greenhouses also has a great impact on the quality of greenhouses, so in order to reduce maintenance costs, there is a better harvest during the planting of crops, farmers should pay attention to whether the selection of materials is reasonable.

　　Build vegetable greenhouses greenhouses material should have some basis and use, so to finish the work by the staff, to ensure the build quality conforms to the standard of greenhouses.
