Design of Leylus-chinensis grassland root-cutter

摘要：

Introduction Eliminating the soil subsurface hard layer and cutting off the transverse roots of Leylus-chinensis to promote its propagation and self-reproduction by a mechanical method is a way to improve degenerated Leylus-chinensis glassland( Yan Zhijian,2002).Shallow ploughing can loosen the soil and promote root system reproduction (Burgess,C.P,2000).
