Mulch Film covers the soil surface and reduces the amount of sunlight reaching the area around the crop, which can restrict the germination and growth of many weeds. By creating a barrier over the soil, it also reduces direct evaporation and helps conserve moisture between irrigation cycles. Different film colors and structures can influence how solar energy is absorbed or reflected, affecting soil temperature. Black films generally absorb more solar radiation and can contribute to soil warming under suitable conditions, while reflective films can reduce heat absorption at the surface. The actual effect depends on the film type, weather, soil characteristics, irrigation practices, and installation method.
