Agricultural plastic mulch is used to cover the soil to control weeds, retain moisture, and regulate soil temperature. The main types include: 1) Clear plastic mulch, which allows maximum sunlight to reach the soil; 2) Black plastic mulch, effective for weed suppression and soil warming; 3) Colored plastic mulch, such as red or blue, which can affect plant growth and pest control; 4) Biodegradable mulch, which breaks down over time and is environmentally friendly; 5) Weed barrier fabric, a permeable fabric that allows water through but blocks weeds; and 6)EVA or PE mulch, which are types of plastic films with different properties for specific agricultural needs. Each type serves different purposes and is chosen based on the crop and environmental conditions.
