湘南地区不同粳稻品种适应性研究

Adaptablity Research of Different Japonica Rice in South Areas of Hunan

为探索粳稻在湖南省作晚稻种植的特征特性及栽培技术,加快形成"早籼晚粳"的双季稻生产格局,特引进粳稻品种开展适应性研究,以期选择出优质、高产、高抗,适合湘南地区的中晚粳新品种。研究结果表明:通过对不同粳稻品种产量和产量构成因素的比较分析,春优84、晚粳30和晚粳19可选择作为湘南丘陵区晚粳种植品种,产量分别达到558kg/667m2、605kg/667m2和663kg/667m2。

In order to explore the growth character and cultivation techniques of late japonica rice in south areas of Hunan, to promote the double rice production of early indica rice and late japonica rice, japonica rice varieties were studed to screening the high quality, high yield and high resistance rice varieties which are appropriate to cultivate in south areas of Hunan. The results showed that from the analysis of yield and yield components of different japonica rice, Chunyou 84, Wanjing 30 and Wanjing 19 are appropriate to cultivate in upland of Hunan, the yield of which are 558kg/667m2 , 605kg/667m2 , 663kg/667m2 , respectively.
