What are the different types of seedbed preparation methods using agricultural plastic mulch?

Agricultural plastic mulch is used to enhance soil conditions and crop growth. Different types of seedbed preparation methods include: 1) Ridge Mulching, where the soil is raised into ridges and mulch is applied to retain moisture and warmth; 2) Flat Mulching, where the soil is leveled and mulch is laid flat, suitable for mechanized planting; 3) No-Till Mulching, a conservation method that leaves the soil undisturbed and applies mulch directly over the previous crop residue; 4) Strip Mulching, used in row crops where mulch is applied in strips between rows; and 5) Black Mulching, employing black plastic to suppress weeds and absorb heat, warming the soil. Each method is chosen based on crop type, climate, and specific agricultural goals.
