China mulch sheet is a cost‑effective plastic mulching film suitable for small and medium‑scale growers. Laid over prepared beds, it limits sunlight reaching the soil, so weed seeds cannot germinate and compete with crops for water and nutrients. The sheet reduces direct evaporation from the soil surface, meaning less frequent watering and better use of fertiliser applied through drip lines. It also helps maintain a more uniform soil temperature, encouraging strong root development and more consistent plant growth across the field. The 1.2 x 400 m roll length is convenient for continuous rows, polytunnels and greenhouse beds where quick installation and lower material cost are important.
