摘要： 通过田间试验，研究了籽粒含水量、收获时间、行驶速度等因素对水稻机收损失率的影响。结果表明，机械收获时籽粒含水量≥17%和≤15%时均会增加损失率，适宜收获的籽粒含水量为15%~17%；一天之中以7∶00时收获损失率最高，10∶00后收获损失率逐渐降低，建议在晴好天气下10∶00后开始收割；收割机以中档速度行驶时收获损失率最低，高档和抵挡均会增加收获损失率。

Abstract: The effects of different water content of grain, different harvest times in 1 d, different running speed of machine on the loss rate of rice harvest were studied through field experiments. The results showed that, the harvest loss rate could increase when the water content of grain is ≥17% and ≤15% at harvesting, the best water content of grain is 15%~17%; the harvest loss rate was higher at 7 o'clock, the loss rate gradually decreased after 10 o'clock, it is suggested to start harvesting after 10 o 'clock in fine weather; the loss rate was the lowest when the harvesting machine running at medium speed.

Key words: rice, mechanical harvest, reduce loss
