Abstract:

Comparative analysis was carried out on yield and benefits of mechanical transplanted, hand-transplanted and direct seeding of indica-japonica hybrid rice Yongyou 538. The results showed that the yield of mechanical transplanted was highest, followed by hand-transplanted and direct seedling, but the yield all exceed 750 kg/667 m2. From the point of view of cost, the cost of direct seeding was the lowest, it is suitable for small family planting. Because of low seed dosage, low seed cost and convenient management, hand-transplanted was also a good choice for small family planting. However, the machine-transplanted cultivation technique was the best choice for large farming, because the shortage of labor and seasonal needs.

Key words: Yongyou 538, single cropping rice, mechanical transplanted, direct seeding, hand-transplanted

摘要：

以甬优538为试材，比较分析了其在机插、直播、手插等栽培方式下的产量和种植成本差异。结果表明，甬优538作机插时产量最高，手插次之，直播略低，但三者的产量均超过750 kg/667 m2。从种植成本看，以直播最省工节本，大部分小户选择了此种栽培方式；手插栽培方式由于用种量少，种子成本低，且后期管理方便，也是小户种植不错的选择；但作为大户，由于劳力、季节紧张，还是选择机插为佳。
