How to improve the Light transmittance of the latest greenhouse Agricultural Film

During the use of greenhouse film, due to pollution, attachment of water droplets and dust, the light transmittance will be greatly reduced, which will seriously affect the photosynthesis of crops, which is extremely disadvantageous to crop growth. So farmers need to take measures to improve the light transmittance of greenhouse film, so what should be done? Let's take a look.

First, how to improve the light transmittance of agricultural film

1. Cleaning

In order to improve the light transmittance of the greenhouse film, in addition to designing the lighting angle and promoting the use of the drip-free film, it should be cleaned every other week during use, so that the dust and broken grass on the greenhouse film can be cleaned up. It can improve the light transmittance of greenhouse film by 5% and 8%.

2. Dry fine soil or gypsum powder

In the process of cultivation in the greenhouse, there is no humidity in the greenhouse, and the greenhouse film will have water droplets attached anyway, which will also affect the light transmittance of the greenhouse film. Before laying, sprinkle fine soil or gypsum powder on the greenhouse film, wipe it repeatedly with towels or cloth pieces, and then wipe it clean, and then deal with one side inward, so as to reduce the adhesion of water droplets to the greenhouse film.

3. Spray soybean powder

Dry fine soil or gypsum powder can only be maintained for a period of time, and then there will be water droplets attached, then you can grind soybeans into fine powder, 7.5-10 grams of soybean powder per square meter of greenhouse film, 150 grams of water, soak for 2 hours, filter with fine gauze, remove dregs and spray the water droplets on the greenhouse film with a sprayer. This can make the droplets fall quickly and keep them from forming new droplets for half a month or so.

4. Turn over the greenhouse film

You can choose a windless, sunny noon, remove and flip the film, so that the original upward side down, and then fixed, which can also reduce the adhesion of water droplets and greatly improve the light transmittance.

Second, dust removal skills

Washing with water in high temperature and humidity does little harm to the greenhouse film, but in the low temperature season, if it is washed with water, it is easy to freeze and difficult to implement. If you use manual wiping, it will inevitably scratch the greenhouse film, and will make the greenhouse film fouling, resulting in a decline in light transmission performance, although these two methods are available. But it takes time and effort. A strip of cloth with a width of 0.5 to 0.7 meters can be placed on the greenhouse film every 1.2 meters, and both ends are tied to the steel wire, so that the wind can be used to swing the cloth to remove dust.
