The invention relates to a wide-ridge platform Vigna radiate L.Wilclzek cultivation method, and belongs to the Vigna radiate L.Wilclzek cultivation technical field; the method comprises the following steps: autumn ploughing and ridging, building furrows on two sides of the ridge, building a ridge platform for the ridge, respectively deep ploughing the furrows and the ridge platform middle portion, using the field surface before ridging as reference, the furrow subsoiling depth is 30-40cm, and the ridge platform middle subsoiling depth is 15-30cm; applying base fertilizer in middle of the ridge platform in soil preparation; applying seed manure under sowing positions; sowing Vigna radiate L.Wilclzek on the ridge platform in 3 lines, forming 3 seedling strips, wherein the sowing line space is 25-30cm, and the Vigna radiate L.Wilclzek variety is an erection or semiprostrate lodging resistance high yield Vigna radiate L.Wilclzek kinds; respectively applying additional fertilizer outside the seedling strips on the left and right sides of the ridge, and applying additional fertilizer under the ridge platform. The cultivation method combines subsoiling, sowing with fertilizer application, is good in permeability and strong in stress resistance, thus improving Vigna radiate L.Wilclzek colony photosynthesis production efficiency and fertilizer utilization rate, and realizing Vigna radiate L.Wilclzek highyield high-quality high efficiency production.
