对姜堰区246户农户、125.38 hm2水稻不同种植方式进行了随机调查。结果显示，在高产水平上，机插秧的产量略低于抛秧，但比直播稻高31.0 kg/667 m2；在中、低产水平上，机插秧的产量略高于抛秧，比直播稻高50.0 kg/667 m2左右。机插秧的成本比抛秧、直播方式低，而净效益却比抛秧高48.2元/667 m2，比直播稻高166.8元/667 m2。表明机插是姜堰区目前3种主要种植方式的最佳选择，也是今后水稻机械化生产的方向。%According to the survey of 246 farmers, 125.38 hm2 rice with different planting methods in Jiangyan district, the authors found out, the yield of machine transplanted rice was slightly lower than that of seedling throwing rice in high yield level, but was higher than direct seeding rice by 31.0 kg/667 m2; in middle and low yield level, the yield of machine transplanted rice was slightly higher than that of seedling throwing rice, and higher than direct seeding rice by 50.0 kg/667 m 2.
