| Abstract: | Structural improvement is mode on the outer groove wheel seeding driller.Three kinds of drillers are chosen as the contrast.The results show that the precision driller of grain with an elastic seed scraping equipment can meet the agricultural requirement of precision seed for wheat.The indexes of its performance,including the coefficient of consistent variation of seeding amount to every line,the coefficient of stable variation of total seeding amount , the breakage ratio of seeds, the coefficient of equal variation of seedings in field, and the breakage ratio of strips, tested in laboratory and field,are all superior to those of other drillers. |

| Keywords: | driller elastic seed scraping equipment coefficient of variation equal degree of seeding |
