手稻

机插与手栽稻生长发育、产量及品质差异的比较研究

Differences on Growth , Yield and Grain Quality of Rice Transplanted by Rice Transplanter and Hand

手栽稻分蘖发生叶位数多，且茎蘖成穗率高，单株成穗数多；

The number of tiller leaf position of artificial transplanting rice was more , earbearing tiller percentage was higher and panicle number per plant was more .

水稻机械化直播是一项轻型、省工节本、高产高效、农机与农艺相结合的新型栽培技术。与手栽稻相比，具有生育期缩短、总叶龄数减少；

Mechanized direct sowing of rice is one new light type culture technique with labour saving , high yield and efficiency , combining agricultural machinery and agronomy .

结果表明，不同栽培方式水稻产量差异极显著，手栽稻最高，直播稻最低。

Results showed that rice yields by using different cultivation methods were significantly different , artificial transplanting rice was highest , while direct seeding rice was lowest .

对抛栽稻和手插稻的比较试验表明：（1）抛栽稻的生育优势有：分蘖早，分蘖多，有效穗多；

Comparison test of seedling - throwing culture ( STC ) and hand-transplanting culture ( HTC ) in rice showed that : ( 1 ) Growth and developmental superiorities of rice by STC were : earlier emergence of tiller , more tiller and effective panicles ;
