Abstract: The transplanter with chute was developed with no-tillage working unit mounted. Results of field tests with no-tillage and mulch showed that the quality of transplanting can meet the need of agricultural production. The excellent rate and the up-to-standard rate of the summer corn seedlings verticality can reach 74.4% and 91.8% respectively. Variation coefficient of transplanting depth and Variation coefficient of the distance between seedlings were 14.9% and 6.4% respectively. Each performance index of transplanting with no-tillage & mulch had no remarkable difference with that of ploughing. Compared with mulch seeding of summer corn with no-tillage, the increased profit of 521～1 574 yuan RMB/hm² was obtained.
