1. It solves the problem of fog diffusing in the plastic hothouse and increases the illumination time and intensity in the hothouse. The light intensity of this defogging film is 20- 25 more advanced than that of the ordinary film when fog occurs. It can raise the temperature of the hothouse and the ground by 1- 2C.
2. Because of the effect of the defogging cumulative, the film’s-dripping performance is greatly increased. The humidity in the air in the hothouse is absorbed and removed by the defogging agent snappily, and the air moisture is 10- 12 lower than that of the ordinary-dripping film.
3. It greatly reduces the damage of the complaint, the times of scattering, and the quantum of the drug. The function of defogging causes the fog in the hothouse isn’t diffused, so the air moisture is reduced and the complaint is greatly reduced. Particularly, the fungus infection conditions on the face of leafage( similar to cucumber downy mildew, fine mildew, melon fine mildew, and so on), which are dangerous to vegetables and melons.
4. It’s salutary to cover watermelon, Muskmelon, and fruit trees in defended fields by unfolding and pollination. Meanwhile, it improves the fruit setting rate and quality.
5. In the plastic hothouse of beast and flesh in downtime, because of the small fog and low moisture, it can reduce the
respiratory conditions and spongers of flesh.

Greenhouse film’s utilization rate

In recent years, with the development of facility agriculture, the area of planting greenhouses has also been expanding. However, during the use of the greenhouse film, its lifespan is actually not long, and replacing the film is time-consuming, laborious, and expensive. We often say “open source and reduce expenditure”, “reducing expenditure” can be said to be one of the ways to obtain high benefits in the process of agricultural production, so it is very important to improve the utilization rate of greenhouse film. So, how to improve the utilization rate of agricultural greenhouse film? The methods to improve the utilization rate of greenhouse film are introduced as follows.

Introduction to the method of improving the utilization rate of the film in the greenhouse

1. The seam must not be too narrow:

the greenhouse film is spliced by a number of narrow-width films. When splicing, the bonding area should be increased to improve the bonding strength. If the seam is too narrow, cracks will be caused when the bonding area is small and pulled hard.

2. Press the film with a line:

After the film is covered with a greenhouse, it should be pressed with a film line immediately. Generally, a laminated line is pulled every 1-2 scaffolds, the line should

be moderately tight, and a simple windproof barrier should be set up on the windward side.

3. Film damage needs to be repaired:

The film is easily damaged during use and storage, and temporary repair methods can be used for damage during use. There are two methods:

one is the water repair method.

Scrub the damaged area, cut a piece of film that is slightly larger than the damaged area without holes, dip it in water and paste it on the hole, drain the air between the two films, and press the flat Yes;

The second is the paper repair method.

If the agricultural film is slightly damaged, use paper to dip it in water and paste it on the damaged area while it is wet. Generally, it can be used for about 10 days. The damaged film after the shed is dismantled shall be permanently repaired. If the thicker film is damaged, it can be covered with a film of the same texture and connected with a thin thread. You can also wash the damaged part, cover the hole with a slightly larger film, and then cover it with 2-3 layers of newspaper, and gently iron it along the interface with an electric iron.

Together, this method is called a hot tonic. In addition, there is a glue repair method. Clean the surrounding area of the hole and apply it with a brush dipped in special glue. After 3-5 minutes, take a piece of film with the same texture and stick it on it. After the glue dries, it can be stuck firmly. The hot patching method and glue patching method have good film patching effects, and the sewing patching method not only leaks air, but also is easy to pull apart, so it is best not to use it for films that are not thicker in texture.

4. Digging and burying when not in use:

During the storage period of the film, it is necessary to strictly prevent exposure to the sun, smoke, and fire, otherwise, its service life will be greatly shortened. The best way to store the shed film is to dig a hole and bury it. After the production is over, the removed film should be washed and dried first. After being rolled up, it should be wrapped with the old film. Choose a place with moderate soil dryness and humidity to dig a pit, and then wrap the film A good film is buried in a pit. Note that the distance between the upper layer of the film and the ground is more than 30 cm. This method can prevent the agricultural film from becoming brittle and shorten its service life when it is stored in the air.
