The invention relates to a method for drip irrigation vegetable planting below a dry slope land membrane. The method comprises the following steps of leveling and compacting land, and arranging ridge-bordered plots; laying drip irrigation zones before sowing; before sowing or field planting, tiling an agricultural membrane on the laid drip irrigation zones, compressing the periphery of the membrane with soil, and using a hole puncher for punching holes in the positions, on the two sides of each drip irrigation zone, of the agricultural membrane, wherein the hole distance is determined according to the requirement for the row spacing of planted crops; connecting the drip irrigation zones with a water transport and distribution system, and conducting dripping and fertilization timely and quantitatively according to the requirement of the planted crops to achieve integration of water and fertilizer. Vegetables are planted by the adoption of the drip irrigation method, so that crop root development zones are uniformly, timely and quantitatively soaked; in addition, due to land membrane coverage, crop plant evaporation is greatly reduced, manpower and fertilizer input is reduced, and the water resource utilization rate is improved; vegetables are planted on a dry slope land through the method with the combination of drip irrigation and the land membrane, so that on the premise that the drought resistance ability of the whole production system is improved, the mechanical degree (the land utilization rate) is improved, labor and fertilizer are saved, water is saved, and the yield is increased.
