摘　　要：以武运粳23号为材料,比较了机插、抛栽、机条播和手撒播等4种不同轻简栽培方式对水稻生长发育、产量和效益的影响。结果表明,产量高低表现为抛栽﹥机插﹥机条播﹥手撒播,不同方式间差异显著;效益表现为抛栽﹥机条播﹥机插﹥手撒播,不同方式间差异达显著或极显著水平。根据试验结果,对无锡地区不同轻简栽培方式的选择、高产高效途径及其关键技术提出了合理建议。Effects of machine transplanting, manual soedhng throwing, machine drill sowing and manual casting on growth, yield and benefit of rice were compared using wuyunjing 23 as the material. The results showed that the sequence of the yields from high to low is manual seedling throwing, machine transplanting, machine drill sowing and manual casting, while the sequence of the benefits from high to low is manual seedling throwing, machine drill sowing, machine transplanting and manual casting. The yields and benefits reach significant differences or extremely significant differences by analysis of variance. According to the test results, some valuable suggestions were put forwarded. The different cultivation methods are recommended to use in different areas in Wuxi City. The way to reach high yield with high efficiency and its correspondingkey technology were also discussed in the paper.
