内蒙古托克托县当地灌溉水的含盐量常年保持在3.0‰~5.5‰水平，严重影响水稻的生长发育。为推进当地水稻产业的发展，针对当地盐碱水土环境，开展了耐盐碱水稻品种筛选试验。结果表明，随着插秧时间的推移，11个参试品种的秧苗成活率存在显著差异，在插秧后30 d，吉粳113、吉粳301、吉粳515的成活率降低到50%以下，而松粳9、粳优315、S7、粳优653仍保持在90%以上，表现出较强的耐盐性；杂交稻品种的成苗率要远高于常规稻品种；参试品种的株高都低于该品种在正常环境下生长的株高；除松粳9、粳优653的穗长接近正常值外，其他品种均受到明显抑制；松粳9、粳优653的产量表现较突出，可以作为当地及类似生态区推荐种植品种。

The salt content of the local irrigation water in Toketo County, Inner Mongolia has been maintained at a level of 3.0 ‰ to 5.5 ‰ all year round, which seriously affects the growth and development of rice. In order to promote the development of the local rice industry, a screening experiment of saline-alkali-tolerant rice varieties was carried out for the local saline-alkali water and soil environment. The results showed that, there were significant differences in the survival rates of the 11 tested varieties with the transplanting time. 30 days after transplanting, the survival rates of Jigeng 113, Jigeng 301 and Jigeng 515 decreased below 50%, while Songgeng 9, Gengyou 315, S7 and Gengyou 653 remained above 90%, showing strong salt tolerance. The seedling rate of hybrid rice varieties is much higher than conventional rice varieties. The plant height of the tested varieties is lower than that of the variety grown under normal environment. Except the panicle length of Songgeng 9 and Gengyou 653 were close to normal value, the other varieties showed significant inhibition. In the experiment, the yields of Songgeng 9 and Gengyou 653 are outstanding, which could be used as the recommended varieties planting in local and similar ecological areas.
