于是，我用木铲把一块地挖松，并把这块地分成两部分播种。在播种时，我忽然想到，不能把全部种子播下去，因为我尚未弄清楚什么时候最适宜下种。这样，我播下了三分之二的种子，每样都留了一点下来。 - When seeding , this system automatically regulates the speed of the seed - sowing device according as the demand of sow quantity and the speed of the seeder . this speed is acquired by sensor . the land wheel skid and rough ground will influence the quality of seeding , then , by using this system the influence may be decreased
此系统在播种时，可以连续采集五轮仪的转速，并根据五轮仪的转速和作物播量要求调整排种器的转速；系统可以减小地轮打滑及地面不平对播种质量的影响，从而达到精量播种的要求。
