| Abstract: |
| The type of 2BMQL－3ridge-till and no-till corn planter is designed to solve the problems of difficult to seed in form ridge and difficult to protect the shape of form ridge that exist in the present planter．This planter is formed with corn rootstalk-cutting device ridge-cleaning device stabilizing device opening and fertilizing device soi-l covering device and pack roller and so on．The results approved that the planter could realize no-till planting in form ridge while protecting the ridge against destroying．The qualified rate for space of seeds is 96．2％ and the average depth of seeds and fertilizer and the distance between them are 4．2cm， 8．7cm and 4．5cm．This planter could perform the corn rootstalk-cutting opening fertilizing seeding packing and covering operations at one time. |
