盐害是影响着全球三分之一灌溉地的严重问题。在热带、亚热带地区盐碱地达1500万公顷。我省盐碱地600万亩,西部大部地区属于盐碱地。如何开发利用盐碱地资源,扩大水稻种植面积,提高水稻产量,是亟待解决的重大问题。盐碱障害可通过水分灌溉、施用化学改良剂,进行土壤改良,但常因耗资大、见效少而难以实现。选育耐盐碱水稻新品种,则是最可靠 Salt damage is a serious problem affecting one third of the world’s irrigated land. In the tropical and subtropical areas up to 15 million hectares of saline land. Salt Lake in our province 600 acres, most of the western part of saline land. How to develop and utilize the resources of saline land, expand the area under rice cultivation and increase the output of rice is a major issue to be solved urgently. Saline-alkali barrier can be through the irrigation of water, the application of chemical modifiers, soil improvement, but often due to costly, less effective and difficult to achieve. Breeding salt-resistant rice new varieties, it is the most reliable
