2009年在宁乡县、桃源县、永兴县3地冷浸田条件下进行了品种筛选和不同栽培方式的比较试验。结果表明:（1）不同品种在3个地点产量表现基本一致,早稻以陆两优996和陵两优211表现较好,平均产量分别达到5.68 t/hm2和5.28 t/hm2,晚稻以钱优1号、天优华占和丰源优299表现较好,产量分别达到5.08,4.94和4.81 t/hm2;（2）不同栽培方式产量表现地点间不一致。桃源点早稻和晚稻以翻耕移栽和免耕抛栽产量较高,永兴点早稻免耕抛栽产量最高,晚稻以垄厢移栽产量最高,宁乡点早稻和晚稻都以翻耕移栽产量最高。

The comparison experiments with different varieties and cultivation methods were conducted in cold water paddy fields in Ningxiang,Taoyuan and Yongxing County in 2009.The results showed that（1） the yield performance among cultivars was similar in three locations,LLY996 and LLY211 showed higher yield in early season rice cultivars,of which averaged as 5.68 and 5.28 t/hm2 in three locations respectively,and QY-1,TYHZ and FYY299 showed higher yield in late season rice cultivars,of which averaged as 5.08,4.94 and 4.81 t/hm2 in three locations res...
