Suzhou Keming Agricultural Machinery Co.Ltd., Suzhou 234113) Abstract: In order to solve the problem of suspension seed and hanging seedling in no-tillage seedling ma- chinery, we designed a no-tillage planter with smashing straw and fertilization, which can complete straw crushing and returning to the field, seeding in clean area, fertilization on the side at one time. The structure of the machine is simple and the straw is sprinkled evenly. The structure and working principle of the machine were described in deta
