Shouzheng Knowledge Class: What Is Agricultural Film

Agricultural film is a kind of plastic film used in agricultural production, is also the general term of plastic film used in agricultural production, agricultural film as one of the main covering materials of greenhouse, plays an important role in the construction of high yield and high quality agriculture.

The main component of agricultural film is polyethylene, which is mainly used to cover farmland, which can improve the ground temperature, maintain soil humidity, inhibit the growth of weeds, promote seed germination and rapid growth of seedlings, so it plays a very important role in moisturizing and insulation during the sowing period.

The characteristics of agricultural film mainly include length, width, thickness, color and performance, about the length and width, I believe you all understand, next, we will introduce the thickness, color and performance of agricultural film.

1. Thickness Of The Agricultural Film:

The thickness of the agricultural film is usually measured as "microns". The larger the thickness, usually the better the durability, but the higher the price. The thickness of the agricultural film should be based on your specific needs. How to choose the thickness, we Shouzheng has the following suggestions:

20-25 microns: suitable for short-term coverage, such as pre-sowing coverage of early-maturing vegetables.

30-40 microns: Suitable for seasonal purposes covering vegetables, fruits and flowers.

50-100 microns: suitable for long-term coverage, such as annual greenhouse planting or multi-season crops.

2. Color Of Agricultural Film:

The color of the agricultural film has a certain impact on its performance and function. Here are some common colors and their functions:

Black: Black agricultural film absorbs sunlight, raises soil temperature, helps early and warm crops.

Silver: Silver agricultural film reflects sunlight, reduce the soil temperature rise, suitable for summer high temperature protection.

Transparency: transparent agricultural film has good light transmittance, suitable for plants that need more sunlight.

White: white agricultural film is suitable for greenhouse, help to reduce the greenhouse temperature.

3. Performance Of The Agricultural Film

About the performance of agricultural film, mainly including transparency, light transmittance, tensile resistance, durability, anti-aging, etc., which requires us to choose according to the specific needs.

Agricultural film with good transparency and light transmittance can ensure the photosynthesis effect of crops and promote the growth and development; the tensile force and durability are related to the thickness of the agricultural film, the better the tensile resistance; the insulation performance of agricultural film is related to geographical environment, and different agricultural films are suitable for different geographical environment and climatic conditions, such as cold areas, and high temperature areas.
