农业科研试验多为小区种植,品种(系)多,播种量不一,行距要求准,播种质量要求严.实现试验地播种机械化难度较大.我所的试验地以往多采用人工播种,质量差,增加了试验误差.为了提高试验地播种效率,保证播种质量,达到试验地出苗全、匀、壮的要求,我们研制了一台试验单行播种机,在棉花试验地进行 Most of the agricultural scientific research is plots planting, more varieties (lines), different sowing, quasi-row spacing, strict requirements on sowing quality.It is very difficult to realize mechanization of sowing in experimental site.In the past, , To increase the test error.In order to improve the sowing efficiency of the experiment, to ensure the sowing quality, to achieve the test of seedling emergence, uniform and strong requirements, we developed a test single row seeder, carried out in the cotton test
