指夹式排种器工作性能的好坏主要决定于指夹器、颠簸器和排种带三者工作性能的优劣。指夹器主要影响充种性能,颠簸器主要影响清种效果,使每穴只播一粒种子。这二者之间又互相影响,不能截然分开,从而获得较高的播种合格率(见表1和2)。有关这些,在本报一九八四年第二期中已作了介绍,本文将继续对影响排种器工作质量的有关因素进行分析。 The performance of the finger-type seed metering device mainly depends on the performance of the finger gripper, the jigger and the seed placement belt. Finger clamps mainly affect the filling performance. The jumbler mainly affects the effect of seed clearing, so that only one seed per hole can be sowed. The two also affect each other and can not be completely separated, resulting in a higher rate of seeded seeding (see Tables 1 and 2). These are described in the second issue of the newspaper in 1984, this paper will continue to analyze the factors that affect the quality of the planter work.
