摘　　要：通过实验证明了水稻抛秧技术高产高效,本文对其原因作了浅析,由于抛秧具有秧苗根系保护好、成活率高、分蘖早、节位低、通风透光好、生育后期的冠状结构、光合生产率高、根叶活性增强、病虫害轻等优点,所以抛秧的秧苗穗大、子粒饱满、千粒重增加,并且抛秧技术省工、省力、节约成本,既增产又增效。The factors for high yield and high efficiency by scatter-transplanting in rice are well protected seedling roots with high surviving rate, early tillers with low intemodes, well structured canopy at later stage with higher photosynthetic rate, active leaves with less damage by pest insects and diseases. Therefore, the big panicles, fully ripened grains and high 1000-grain weight as well as saved labor and cost, scatter-throwing in rice showed high yield and efficiency.
