In the winter, it is very important to set up the cold shelters for the sheds. However, at present, most shelters do not have a cold-proof ditch, or the cold-proof ditch is not reasonable. Some cold-proof ditch is set outside the shed, and some dig a 30-cm wide and 40-cm-deep ditch at the front of the shed. After filling in the grass, it is not managed. People are free to trample and lose their cold protection. Cold-proof ditch should be set to cold storage temperature adjustment ditch, which should be set around the entire booth. The front of the cold-proof ditch should not be set outside the shed, but should be set at the front of the shed. First dig a ditch 30-40 cm wide and 40 cm deep, then lay the old film on the bottom of the ditch, and then use a 90-cm-wide barrel-shaped plastic film from east to west. This film is equivalent to a pipe. The film tube is filled with water. Since the temperature in the front of the shed indoors is 2°C~3°C higher than the temperature in the latter half and the middle, the temperature at the front of the shed is lower by 3°C than the temperature in the latter half of the day, and the vegetables are prone to freeze damage. The film tube is filled with water and absorbs heat during the day, which does not make the temperature in the front of the tent excessively high. At night, the water in the film tube will dissipate the accumulated heat during the day, which has the effect of significantly increasing the front temperature in the shed. . When watering in the future, the irrigated water in the film tube is poured, and the water is poured in warm water, which will not reduce the ground temperature. The cold-proof ditch should be dug in front of the thin film tube, covered with thick wheat straw, and finally covered with a shed film. The soil is pressed on the outside of the shed film. After this treatment, the water on the shed film will flow down to the grass and the wheat straw will be damp. Fermentation will result in the release of carbon dioxide from the fermentation, which will both provide thermal insulation and provide carbon dioxide needed by the plants for photosynthesis. The biggest advantage of this treatment is to solve the problem of soil moisture in the front of the shed. The original greenhouses were covered by the front shed film directly on the ground. As a result, the water flowing down from the shed film was all accumulated in the front soil. Causes the front soil to be too wet, and finally causes downy mildew and gray mold in the front vegetables. The further spread of the disease will spread the entire greenhouse. The gables and the rear half of the shed should also be equipped with a cold-proof ditch. Dig a trench that is 20 cm wide and 30 cm deep, fill it with wheat straw, and step on it without having to cover the membrane. These wheat straws can prevent the spread of heat and they can absorb moisture and reduce the occurrence of diseases. These wheat straws can also ferment and release carbon dioxide after absorbing moisture, so as to solve the problem of insufficient carbon dioxide in the shed. Therefore, the cold-proof ditch must be set in the shed, not outside the shed, and the front and rear halves of the gable and shed should be set. Pressure Compensated Emitter Products
