摘要
通过对垂直型孔轮式排种器结构及技术参数的优化选择,找到了该排种器适应高速精密播种的途径。从而打破了此类排种器不能适应高速精密播种的局限,使之成功地适应了12km/h的大豆、玉米等中耕作物的高速精密播种。
In order to meet requirment of high ground speed(12km/h ) planting, the radial seed cell type seeder has been modified. Its mechanism, design and field test of the modified type of seeder are described in the paper.
