一、前言吉林省有大面积盐碱洼地有待开发种植水稻,为了探索开发的路子,我们于1985—1987年承担了吉林省科委下达的“盐碱洼地开发种稻研究”的招标课题。本研究基点设在农安县,该县位于长春市西北部,在北纬43°55′—44°56′之间,5— I. Preface Jilin Province has a large area of ​​saline-alkali depression to be developed for planting rice. In order to explore the development path, we undertook the tender topic of “Study on the Development of Rice in Saline-alkali-depression Development” issued by Jilin Science and Technology Commission from 1985 to 1987. The research base is located in Nong’an County, which is located in the northwest of Changchun City, between 43 ° 55’-44 ° 56’N and 5-
