Abstract: With continuous development of modern agricultural science and technology，mechanization technology has been widely used in many agricultural production fields in China.The theoretical basis of mechanized ridge free cultivation comes from the study of wheat biological characteristics，while the technology comes from the rapid and uniform planting function of mechanized equipment，so that wheat seeds can be evenly distributed in appropriate environment and soil layer.Biological characteristics of wheat and yield increasing mechanism of mechanized ridge free cultivation were analyzed theoretically.Based on actual planting situation of a county in Pingdingshan city，Henan province，application points and benefits of mechanized ridge free cultivation of wheat were analyzed.And problems in application of this technology were discussed.Finally，prospect of application and popularization of mechanized ridge free cultivation of wheat was prospected，and some suggestions were put forward.
