Plastic Net Manufacturers Tell You How to Choose Mulch Film

Agricultural mulch film refers to a thin agricultural film that directly covers the cultivated land or near the ground. The general thickness is 0.008~0.015mm. The base resin vinegar is polyethylene. In recent years, various colored agricultural films have been launched one after another. Due to the different absorption and reflection rules of the spectrum, the agricultural films of different colors have different effects on the growth of crops, weeds, pests and diseases, and ground temperature. Modern mulch has developed from ordinary mulch to various colored mulch and multi-functional special mulches such as weeding and insect control.

Therefore, in use, different colors of agricultural film should be selected according to the characteristics of different crops and planting seasons.

Ordinary mulch film:

The thickness is 0.015 mm, and the width is 8030 meters. Different specifications can be selected according to the width. After mulching, it can improve ground temperature, moisture retention, mulch, and improve fertilizer efficiency. There is also a certain reflective effect to improve the light receiving conditions of the leaves in the lower part of the plant. Suitable for use in spring and autumn.

Black mulch film:

Because the starting point of designing mulch film is to control weeds through physical effects. Carbon black is added to polyethylene, because weeds need light to grow, so the black mulch film does not have light to enter, and weeds cannot grow under the film, so that weeds will not absorb the nutrients of the crops.

Silver black reflective mulch film:

The price is more expensive than black mulch film and transparent mulch film, but their effects are different. The silver side faces up to reflect, and the principle of light refraction can reduce the temperature under the film under the high temperature weather in summer, and will not burn the roots of the crops. Because the light is refracted on the back of the leaves, aphids cannot survive because they are afraid of light, and it has the effect of repelling insects. The fruit has a good luster due to the reflection of light. Therefore, the silver-black reflective mulch film has the functions of weeding, heat preservation, moisture conservation, and insect repellent.
