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

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

greenhouse with plastic film
Greenhouses with plastic film

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.

The special plastic film used in the production and construction of facility agriculture has better light transmittance, heat preservation, and tensile and aging resistance than ordinary agricultural film. It is of great significance to the growth of greenhouse crops, increasing production, and increasing income.

There are many kinds of plastic greenhouse films, and different greenhouse films have different functions. Acctruly, the thickness of the greenhouse plastic film has a great relationship with the growth of crops. The greenhouse film is a plastic product. In summer, the greenhouse film is exposed to the sun for a long time, and it is easy to age and become brittle, which is also related to the thickness of the greenhouse film. If the greenhouse film is too thick, it will cause an aging phenomenon, and if the greenhouse film is too thin, it will not be able to play a good role in temperature control. Furthermore, the thickness of the greenhouse film is also related to the type of crops. Crops, flowers, etc. need to choose different greenhouse film products according to their growth habits.

What kinds of greenhouse films are needed to build greenhouse plastic films?

Commonly used plastic greenhouse films are divided into PO agricultural film, PE agricultural film, EVA agricultural film, and so on according to the material.

PO agricultural film:

PO film refers to the agricultural film made of polyolefin as the main raw material. It has high tensile strength, good thermal insulation performance, and can well protect the growth of crops. Tensile strength means that the agricultural film needs to be pulled tight when it is covered. The tensile strength is not good and it is easy to tear. Good thermal insulation is the most basic requirement for crops. The temperature and humidity control inside the agricultural film is different from the environment outside the greenhouse film. Therefore, PO agricultural film has a good temperature and humidity control effect, which is very helpful to the growth of crops and is deeply loved by people.

PE agricultural film:

PE film is a kind of polyethylene agricultural film, and PE is the abbreviation of polyethylene in English. Polyethylene is a kind of plastic, and the plastic bag we use is a kind of PE plastic product. Polyethylene has excellent chemical stability and is resistant to hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, amines, sodium hydroxide, potassium hydroxide, and other chemical substances at room temperature, but nitric acid and sulfuric acid have strong resistance to polyethylene. Destructive effect; polyethylene is prone to photooxidation, thermal oxidation, and ozone decomposition, and is prone to degradation under the action of ultraviolet rays. After being irradiated, reactions such as crosslinking, chain scission, and formation of unsaturated groups can occur.

EVA agricultural film:

EVA film refers to the agricultural film product with ethylene-vinyl acetate copolymer as the main material. The characteristics of EVA agricultural film are good water resistance, good corrosion resistance, and high heat preservation.

Water resistance Closed cell structure,non-absorbent, humidity- evidence, good water resistance.
erosion resistance resistant to seawater, oil painting, acid, alkali, and other chemical erosion, antibacterial, non-toxic, tasteless, and pollution-free.

Thermal insulation: heat insulation, excellent thermal insulation, cold protection, and low-temperature performance, and can withstand severe cold and sun exposure.

How to choose the thickness of the greenhouse film? The thickness of the greenhouse film has a great relationship with the light transmittance and also has a great relationship with the effective service life.
Effective use period: 16-18 months, the thickness of the purchased shed film is 0.08-0.10mm

Effective use period: 24-36 months, the thickness of the purchased shed film is 0.12-0.15mm

The thickness of the shed film used in multi-span greenhouses needs to be more than 0.15 mm.

3. Excellent thermal insulation performance

The high-quality thermal insulation agent is added to the film, so that most of the heat radiated and conducted outside the shed is reflected back, which effectively locks the shed temperature, ensures the temperature required for crop production, and promotes the crops to be marketed in advance.

4. Long service life

Super anti-aging additives are added to the film, which has a longer service life. The longest service life of 0.15mm thickness can reach more than 5 years, which is suitable for the application of multi-span greenhouses.

5. Super stretch resistance

A large amount of American Exxon high-tech polyolefin raw materials are added to the film, which greatly improves the tensile strength and wear resistance of the film, improves the wind resistance and is more suitable for the use of roller blinds.
Thickness: 0.08mm-0.15mm Width: 1m-16m

Characteristics and advantages of ecological organic PO film:

1. The heat preservation performance is better, the temperature inside thethe shed can be increased by 2 to 3 degrees, the crop yield can be increased, and the market can be brought to market earlier.
2. Crop light is more reasonable and sufficient, thereby improving fruit quality and making crops more productive.
3. The effect of dripping and defogging is more stable. The imported coating liquid is used to increase the thickness of the coating layer so that the effect of dripping and defogging of the film is longer. Due to the thickening of the coating layer, the resistance of the film to the steel wire is improved. abrasion resistance.
4. Higher transparency, imported raw materials are used, and the light transmittance are above 95%, which fully meets the needs of crops for light.

The light transmittance is above 92%, which can rapidly increase the temperature in the shed and promote the growth of crops. Superior thermal insulation can increase the greenhouse temperature by 3 to 5 degrees. The dripping and defogging last for more than 5 months, reducing the occurrence of crop diseases and insect pests in the shed, and ensuring the increase of crop production and income. It is suitable for growing various crops such as cucumbers, tomatoes, eggplants, and peppers.
Thickness: 0.08mm-0.15mm Width 1m-18m

Precautions for installing the greenhouse film:

1. The structure of the greenhouse is reasonable, in line with the shed structure recommended by the Ministry of Agriculture. When closing the shed, try to choose sunny, windless, and warm weather to avoid dragging and friction during the shed installation process, thereby destroying the effect of the coating layer. The tightness of the shed is suitable, and the shed surface is flat. Do not force the film tightly, so as not to damage the coating layer and molecular structure of the film, and affect the dripping and life.

2. When buckling the shed, pay attention to the fact that the raw edge is facing outwards, and it is the correct way to fasten the shed inside the shed.
3. The diameter of the supporting membrane rod should be more than 3cm. Avoid contact and friction between the east-west steel wire; and the shed membrane, which will cause water to drip at the contact point.

4. Spray white paint or anti-rust treatment on the skeleton.

There should be no burrs in contact with the film to avoid stabbing the film. It is forbidden to contact the film with PVC objects to avoid affecting the life of the film due to its reaction.
5. In the first 30 days of use, the shed film has transparent hanging drops, which is a normal phenomenon. As the humidity in the shed increases, the dripping will gradually become normal after the shed is closed.
6. Pay attention to the position and frequency of spraying pesticides, and avoid contacting the membrane surface with pesticides, so as not to shorten the service life of the membrane. Frequent sulfur fumigation will also affect the service life of the agricultural film.
7. In July, August, September, and October of the Gregorian calendar every year, the temperature is too high due to strong sunlight. The service life of the film is calculated as two months for one month.
8. The film should be stored in a cool, dry, clean, and ventilated environment, avoiding sun, rain, and scratches.
