摘　　要：针对玉米植质钵苗栽植过程中出现位移及翻转现象,对玉米植质钵苗栽植运动状态进行了分析。通过理论分析玉米植质钵苗翻转状态和玉米钵苗位移变化规律,建立钵苗落地角度和位移变化方程,得到了钵苗角度及位移变化的曲线图。利用高速摄影对钵苗实际运动情况进行分析,表明曲线与理论分析曲线拟合,验证了理论分析的正确性。当机车前进速度为0.43 m·s^(-1),栽植臂角速度为2 rad·s^(-1)时,得到最佳投苗高度150 mm,钵苗水平位移S=48 mm,落地角度θ=19.3°。为覆土器的研究提供基础。According to the phenomenon of the displacement and turning appeared in the process of corn planting seedling,the motion trail of the corn plant seedling was analyzed. Through the theoretical analysis the state of corn planting pot seedlings and the rule of displacement of maize pot seedling,the equation of seedling landing angle and displacement was established,and the curve figure of angle and displacement of pot seedlings was obtained. High-speed photography was used to analyze the actual movement of seedling,the results showed that the curve corresponded with theoretical analysis curve,which proved the correctness of the theoretical analysis. When the forward speed of the locomotive was 0.43 m·s^（-1）,planting arm angular velocity was 2 rad·s^（-1）,the best height of seedling was 150 mm,the pot seedling horizontal displacement was 48 mm,the degrees of the landing angle was 19.3°.It would provide the basis for the study of casing.
