Greenhouse insulation selection method and advantages of use1

Since my country entered the 21st century, agriculture has developed rapidly, and many rural areas have also improved. Greenhouse insulation is part of the new agricultural construction. The main source of rural economic development is greenhouse planting technology, and greenhouse insulation quilt is an indispensable agricultural equipment in greenhouse technology. What about the environmental management in the greenhouse? The greenhouse mainly has the environment of light, humidity and temperature. These three aspects have a great influence on the development of vegetables. The quality of the light environment is the key to the success of solar greenhouses and greenhouses; humidity is an important factor affecting the quality of vegetables in solar greenhouses; temperature is a prerequisite for the production of vegetables in the high-latitude northern regions in late autumn and winter like early spring. Therefore, for vegetables, adjusting the light, humidity and temperature in the solar greenhouse can improve the yield of vegetable production. The insulation quilt of the greenhouse should be selected from the following aspects: 1. The insulation quilt is the insulation material that is covered on the keel of the vegetable greenhouse. Its pros and cons are directly related to the control of the internal temperature of the greenhouse. For this, people have to choose the material. , Because many greenhouses need to be exposed to the sun on a regular basis, the lighter the weight, the better. 2. Because the greenhouse insulation quilt needs to be blocked on the outer edge of the entire greenhouse and is exposed to wind, sun and rain, its service life has become a key point for people to choose. Some insulation materials look good, but the service life is not. Very short and certainly not a good choice. 3. In the selection of thermal insulation quilts, there are mainly three points: thermal insulation, wind resistance, water resistance, needless to say thermal insulation, wind resistance is mainly to prevent the outside wind from being blown into the shed directly through the thermal insulation, and The same is true for water resistance, which should be able to block the rain when it rains. Four advantages of greenhouse thermal insulation quilt 1. The outside of the greenhouse thermal insulation quilt near the ground is supplemented by heat in the upper air, and the shed will also get this part of the heat because of the blocking of the covering. 2. Because of the softness of the greenhouse insulation quilt, the greenhouse film can be rubbed very brightly, and the light transmittance of the greenhouse film is also enhanced. The photosynthesis of the crops in the greenhouse will be significantly improved, and the quality and yield of the crops will also be improved. greatly improved. 3. It has good wind resistance. Under the same strong wind, because the thermal insulation quilt is soft and adheres closely to the greenhouse film, it is possible to blow over four and a half catties of straw per square but cannot blow the thermal insulation quilt. 4. Greenhouse thermal insulation is used to prevent fungal infection. Compared with straw curtains, when planting fungal crops, the thermal insulation quilt will not cause fungal crop infection. After the straw curtain that can guarantee the light transmittance is used several times, the light transmittance of the greenhouse film will drop significantly, which will directly affect the growth and yield of crops. The use of thermal insulation quilts will avoid such losses.
