During the use of the plastic greenhouse film, due to pollution, adhesion of water droplets and other reasons, it will greatly reduce its light transmission capacity, affect the vegetable lighting, reduce the effectiveness. Farmers should take various measures to increase the transmittance of the greenhouse film.
First, clean the film
To increase the light transmittance of the plastic film in the booth, in addition to designing a good lighting angle and promoting the use of non-drip film, the management should clean the surface of the film with clean water every 5-7 days to clean the dust and smash the grass. Can increase the transmittance of 5%-8%.
Second, dry fine soil or gypsum powder
Flatten the new agricultural film and sprinkle the fine soil or gypsum powder on it. Wipe it with a towel or cloth several times and wipe it clean. When the film is covered, the treated side faces inward, which reduces the adhesion of water droplets.
Third, spray soy flour
The soybeans are ground to a fine powder, 7.5-10 grams of soy flour per square meter of the shed film, 150 grams of water, soaked for 2 hours and then filtered with fine gauze. After removing the scum, spray the water droplets on the shed film with a sprayer. The water droplets fall quickly and keep fresh water droplets for 15-20 days.
Fourth, turn drying film
In the 15-20 days before the frost, the sheds were buckled. After about 30 days, they were selected to be free of wind and sunny at noon. The membranes were removed and turned over so that the original upwards face turned downward and then fixed, which greatly reduced the Water droplets greatly increase light transmittance.
