摘　　要：对滑道分钵轮式栽植器的结构、工作过程、钵体在滑道不同部位的运动状态和受力情况进行了分析 ,并对该栽植器的工作稳定性和立苗率进行了正交和单因素的试验分析。影响栽植器立苗率的因素顺序是钵体含水率 ,钵体侧面形状和滑道倾角。影响栽植器立苗率的主次因素 ,有覆盖物时是 :滑道尾部的离地高度、机具前进速度、滑道倾角 ;无覆盖物时是 :滑道尾部的离地高度、滑道倾角、机具前进速度。找出了栽植器工作稳定性的影响因素及其最佳值和对立苗率影响的因素及其最佳值。The structure and the working process of a slideway parting-bowl-wheel transplanter, the movement and the forced states of a bowl(with soil and seedling) on the slideway were analyzed. The working stability and the seedling-standing ratio of this transplanter were tested and analyzed by the orthogonal and single-factor tests methods. The prior order of the influencing factors for the working stability of the transplanter is moisture content, bowl side shape, and slideway obliquity. The optimal values of the three influencing factors on the working stability were found out. The prior order of the influencing factors for the seedling-standing ratio of the tranplanter is height of throwing bowl, advancing velocity of the equipment, and slideway obliquity for testing with covering. That for testing without covering is height of throwing bowl, slideway obliquity, and advancing velocity. The optimal values of the three influencing factors on the seedling-standing ratio were also found out.
