| Abstract: | The 2BMG-24Q pneumatic no-till wheat planter was designed. Seeds were transported into seeder pipes with high-speed air current to perform precision metering. The wavy disc coulters were used to cut stubble for sowing, and the double disc coulters were used to open furrow for fertilizing. The test results showed that the quanlification percent of seed depth and fertilizer depth were 88.3% and 85.2%, respectively. |
