Technician Experience on the Greenhouse Construction
If you are going to construct your first greenhouse, you can have a look.First, the space of two greenhouse blocks is too narrow. Some farmers wanted to save more land to build a greenhouse; they usually leave a narrow space for the greenhouses. The space is even only 2 meters, which create a hidden danger. Primarily, in the winter, the front greenhouse will shade the behind part, which is not good for vegetable growing. Next, it is very bad for the drainage of flooded fields. It will cause massive snow before the greenhouse when it is snowing. Therefore, the experts suggest that the accurate space for the greenhouses is 4 meters to 5 meters, which not only can avoid shading each one, and also can prevent the wind.
Then, the greenhouse rear slope wall is lack of prevention methods. Some greenhouse growers do not set shading equipment for the greenhouse rear wall. So that part usually is washed by the rain in the summer, which reduces the using time of the greenhouse. Some growers cover a plastic film on the rear part; but withstand the sunburn and windburn day after day; the film is damaged just near one year. Technicians suggest that the rear part of greenhouse should be covered by the plastic film and a layer of non-woven fabrics, and be set by the steel rope each 10 meters. Then the protective method can assure the greenhouse could have 5 years using life.
