Field trials and demonstration of different cropping patterns were carried out to promote the application of direct seeding rice production in Zhejiang Province. The results showed that when planting density was 23 5000/hm2, the yields of mechanical precision hill-direct-seeding rice were similar to hand transplanting rice, but higher than direct seeding rice. The advantages of mechanical direct seeding were early tillering and more tillers. Compared to hand transplanting rice, the grains per spike were decreased by 7.92%, 24.88% and 15.68%, however the effective panicles were increased by 11.75%, 21.92% and 31.11% respectively. Experimental demonstration showed that mechanical hill-direct-seeding rice could achieve high yields.
