摘　　要：为了研究不同种植方式对水稻生产的影响,在水稻旱直播试验示范基地,进行了人工撒播、机械插秧和机械旱直播3种方式的比较试验。试验结果表明:机械旱直播的实际产量最高,比人工撒播和机械插秧分别增产5.96%和4.69%;机械旱直播经济效益最高,采用旱直播方式生产水稻每公顷经济效益比机械插秧和人工撒播方式分别增效30.8%和11.2%;机械旱直播方式的作业效率最高,达到300hm2/h,分别是机械插秧和人工撒播的2.5倍和2倍。可见,机械旱直播是一种"轻简化"且"高产高效"的种植方式。In order to study the effects of different planting methods on rice production, we carried out comparison test of three planting ways including manual sow, mechanical transplanting and mechanical dry direct seeding in rice dry direct seeding experiment and demonstration bases. The results showed that mechanical dry direct seeding highest actual yield than manual sow and mechanical transplanting were increased by 5.96% and 4.69%. Mechanical dry direct seeding highest net profit, using mechanical dry direct seeding way plant rice in net profit per hectare than mechanical transplanting and manual sow, respectively, 30.8% and 11.2%. Operations efficient of mechanical dry direct seeding way reached 300hm^2/h, respectively, mechanical transplanting and manual sow of 2.5 times and 2 times. Visible, mechanical dry direct seeding way to plant rice not only have Simple and convenient, but also achieve the target of high yield, high efficiency and high quality.
