文章针对近年提出的“海水稻”问题，从生产和育种实践的角度，分析了中国引淡水灌溉洗盐的沿海盐土地种稻成功的经验，以及我国水稻耐盐育种取得的突破性创新发展，提出“海水稻”尚不能改变在盐碱地种稻还必须靠淡水灌溉洗盐的基本规律。研究结果为盐碱地耕地保护和粮食生产发展提供了重要参考。

In the light of the problem of “sea rice” proposed in recent years, the successful experiences of the coastal salt land rice planting in China and the breakthrough innovative development of rice salt tolerance in China were analyzed from the point of view of production and breeding practice. It is pointed out that “sea rice” can not change the basic law of salt washing for rice planting in saline and alkali land, which must depend on fresh water irrigation. The research results provide important reference for the protection of saline-alkali land and the development of grain production.
