| 摘 要： | 水稻芽种拌入一定量的干土粉后可以减小芽种之间相互粘连，降低芽种与播种机各部件接触表面之间的粘附力，提高机械播种精度和降低播种过程中的种子损伤率。条播试验结果表明，拌干土粉芽种的播种量标准差为3.6粒，比芽种的播种量标准差少1.36粒；拌干土粉芽种的播种量变异系数为6%，比芽种裸籽的播种量变异系数小2.27%；播种破损率为4.07%，比芽种裸籽播种破损率低5%。

| Abstract: | Rice bud seed mixed with dry soil powder can reduce their internal cohesion force and the adhesion force acted on the surface of a seeder parts, can increase dispersion coefficient, and decrease the broken seed rate when seeding. Test result shows that the rice bud seed is mixed with dry soil powder, the standard variation of a drilling is 3.6 seeds, which is 1.36 seeds less than the rice bud seed without mixed with dry soil; the variation coefficient of uniformity of a drilling is 6%, which is 2.27% less than the rice bud seed without mixed with dry soil; the broken seed rate is 4.07% , which is 5% less than the rice bud seed without mixed with dry soil. |
