摘　　要：设计了一种水稻植质钵育秧盘精量播种机,对影响播种机播种精度的关键参数进行了试验和优化。该机每穴播种3～5粒,一次作业能够完成覆底土、播种以及覆表土等播种作业。经过对该播种机的试验和检测表明:播种均匀度达到98.2%,空穴率为0.01%,单粒率为零,播种生产率为420盘/h,各项指标均达到水稻植质钵育秧盘播种的要求。A kind of precision seeder for rice seedling-growing tray made of paddy-straw was developed. The key factors which had effect on seeder sowing accuracy were tested and optimized. The proposed seeder could sow 3 -5 seeds in each holl and accomplish subsoil covering, seeds sowing, topsoil covering and other processes in one working time. The results showed that sowing uniformity was 98.2% , the ratio of cavity was 0.01% , single grain was 0, and seed production rate was 420 trays per hour, which met the requirements of rice seedling-growing tray made of paddy-straw seeding.
