As the weather gets colder, the sunshine duration becomes shorter and the light intensity becomes weaker. The lack of light has become a major problem in greenhouse vegetable production. Dust on the shed film can seriously affect the light transmittance of the shed film. How to remove this layer of dust has become a concern for vegetable farmers. In the higher temperature season, the method of water flushing is better, and the damage to the shed film is lighter. However, when the weather is too cold in winter, it is washed with water and is prone to freezing. This can cause significant cooling, and there are many difficulties in implementation. The manual cleaning of the shed film will scratch the shed film and cause the shed film to become contaminated, resulting in a decrease in the light transmission performance and a decrease in the light intensity in the shed. Although these two methods are available, they are costly and time-consuming and the results are not satisfactory. If every piece of 1.2m is placed on the shed film, a strip of 5-8cm wide in the north-south direction and 0.5-0.7m longer than the width of the shed film will be attached to the upper vent and the steel wire on the front curtain of the shed, using wind force. The cloth swings and removes dust. The front and back ends of the fabric strip are fixed with the largest amplitude in the middle of the fabric strip, the dust removal rate can reach 80%, the swing amplitude of the two ends is the smallest, the dust removal rate is less than 50%, and no scratches are caused on the shed film. Because this method is relatively simple, there is no need for manual operation after installation, and it is easily accepted by vegetable farmers. More vegetable farmers are used.
