Chernozem is a soil group with calcium carbonate which is found extensively throughout the Heilongjiang province of the People's Republic of China. As one of the main corn belts in the world, the area has continuous planting of corn every year, but that lead to continuous cropping injury. Many corn stalks remain on the soil surface in autumn, so these corn stalks should be buried into the subsoil to retain rainwater underground. This can be accomplished with a special plough which we newly designed and built in this paper. The results show that when the corn stalk length was less than 1000 mm, a smooth burial took place. A total draught of this plough was measured at about 35 kN.
