摘要：

为了筛选适宜南方丘陵山地区域机械化高效生产的水稻品种，采用大田随机区组试验，研究了2个丘陵山地区域典型生态点不同供试晚稻品种机械化种植条件下的秧苗素质、茎蘖动态、产量与品种种植性状等。试验结果表明：低丘地区以品种‘Ⅱ优418’产量最高，达6.855 t/hm2；高丘地区以品种‘岳优9113’产量最高，达6.637 t/hm2。因此，在丘陵双季稻区晚稻机械化种植品种应具有分蘖力强、生育期短和抽穗整齐的特性。

Abstract:

The purposes of this paper are to screening suitable rice cultivars for mechanization planting in hilly and mountains region. The field trials and randomized blocks design experiments were carried out to study the seedling quality, tiller dynamic, grain yield and cultivar planting character of late rice cultivars in two typical hilly and mountains regions. The experimental results indicated that: the yield of ‘ⅡYou418’ was the highest with 6.855 t/hm2 in low mountains region, and the yield of ‘Yueyou9113’was the highest in high mountains region, which reached 6.637 t/hm2. The mechanization planting late rice cultivar should have the characters of strong tiller ability, short growth period and the uniformity of the heading stage in double-rice cropping area of hilly region.
