丘陵早稻机械化种植品种筛选研究

Study on Cultivars Screening of Early Rice Mechanization Planting in Hilly Area

通过比较分析江西省2个典型丘陵生态点8个机械化种植早稻品种的秧苗素质、机插质量、茎蘖动态、产量与品种种植性状,研究筛选适宜南方丘陵机械化生产的早稻品种。试验结果表明:丘陵双季稻区早稻机械化种植品种应具有早熟、分蘖力强、耐寒、抽穗整齐的特性。

The primary objective of this study was to screen cultivars of early rice for mechanization production in south hilly area.Field experiments were conducted in Jiangxi province in 2010,involving eight early rice cultivars and two typical hilly areas.The seedling quality,mechanical transplanting quality,tiller dynamic,grain yield and cultivar planting character were comparative analyzed.The experimental results indicated that the mechanization planting early rice cultivar should have the characters of early maturity,strong tiller ability,cold resistance and the uniformity of the heading stage in double-rice cropping region of hilly area.
