为了筛选适宜于冷浸田栽培的双季稻品种和高产栽培方式,2009年早晚两季在湖南宁乡县、永兴县和桃源县进行了大田栽培试验,结果表明：(1)双季稻产量及其构成因子品种间差异显著,3地点平均产量早稻以陆两优996最高(5．68 t/hm2),晚稻以天优华占最高(5．61 t/hm2)；(2)双季稻不同栽培方式间产量差异显著,3地点平均产量均以垄厢栽培最高,早稻和晚稻分别为5．52 t/hm2和5．81 t/hm2；以传统栽培方式最低,平均产量分别为4．75 t/hm2和5．25 t/hm2。由此可见,选用适宜于冷浸田的双季稻品种,采用垄厢栽培方式有利于获得高产。

To select optimum double cropping rice cultivars and high-yielding cultivation methods adapted to the cold water paddy fields, the field experiments were conducted in Ningxiang county, Yongxing county and Taoyuan county of Hunan province in the early and late season in 2009. The results were showed as follows:(1) There were significant differences in yield and its components among cultivars, and the highest averaged yield in 3 locations reached to 5. 68 t/hm2 ( Luliangyou-996) and 5. 61 t/hm2(Tianyouhuazhan) in early and late season respectively. (2) Significant differences in yield existed a-mong different cultivation methods. The highest average yield in 3 locations under ridge cultivation method was highest, which reached 5. 52 t/hm2 in early season and 5. 81 t/hm2 in late season, and that under traditional cultivation method was the lowest yield, which were 4. 75 t/hm2 and 5. 25 t/hm2 in early and late season respectively. So it is advantageous to gain high yield in cold water paddy field by combination of optimum cultivars and ridge cultivation method.
