摘要： 为促进直播技术在浙江省水稻生产上的应用，进行精量机穴播、撒直播、手插秧等不同种植方式的比较试验，同时进行水稻机穴播的生产示范。研究结果表明，在机穴播密度为23.5万hm2时，杂交籼稻内2优6号、杂交粳稻甬优9号和甬优12的产量和手插秧相近，都显著高于撒直播；机穴播的优势在于分蘖发生早且多，与手插秧相比，内2优6号、甬优9号和甬优12机穴播的每穗粒数分别降低7.92%、24.88%和15.68%，但有效穗数分别增加11.75%、21.92%和31.11%。2012年和2013年进行水稻机穴播生产示范，内2优6号、甬优9号和甬优12的平均产量分别达到9 667.6 kg/hm2、12 285.0 kg/hm2和12 294.8 kg/hm2，进一步说明水稻机穴播高产的可行性。

Abstract: 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.
