摘　　要：为探明免耕移栽对杂交稻产量形成的影响,以川香9838为材料,于2010-2013年在冬水田条件下进行不同栽培方式对杂交稻产量影响的试验。结果表明,与翻耕移栽相比,免耕移栽处理结实率和千粒重较高,产量平均增加了2.27%。可见,冬水田区水稻生产可采用免耕移栽代替传统的翻耕移栽,还能节省整田费用1 875元/hm^2以上。In order to understand the effect of no-tillage and transplanting（NTTP）on yield formation of hybrid rice, a field experiment with hybrid rice combination Chuanxiang 9838 was carried out to study the effect of different cultivation methods（NTTP and conventional tillage and transplanting, CTTP） on grain yield of hybrid rice grown under all-time logged-water paddy filed in 2010-2013. The results showed that the average grain yield of NTTP was 2.27% higher than that of CTTP, mainly due to the contribution of the higher seed setting rate and 1 000-grain weight. The study showed that CTTP could be replaced with NTTP for hybrid rice production in all-time logged-water paddy filed, and save 1 875 yuan per hectare for land preparation.
