Abstract: Effects of machine transplanting, manual seedling 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 corresponding key technology were also discussed in the paper.
