在我国耕地中大约有7%是盐渍土多年来在改良和利用盐渍土方面,做了大量的工作。取得一定成效,其中培育和筛选作物耐盐品种也引起广泛重视。据报道,山东海洋学院从l976年开始从事选育耐盐水稻品种工作,目前已得到移栽后能耐0.5-0.8%咸水,(以氯化钠为主)的品系和中间试验材料;江苏省农科院土壤肥料研究所筛选的耐盐水稻品种80-85在重盐碱地上亩产达到300-400kg。我们从1982年开始进行了大豆品种资源的耐盐性鉴定工作,现将初步结果报道如下。
About 7% of arable land in our country is saline soil. Over the years, a great deal of work has been done in improving and using saline soil. Some achievements have been made, among which cultivation and screening of salt-tolerant crops have also drawn extensive attention. It is reported that Shandong Ocean University started from l976 years of selection of sports porcelain irrigation facilities, has been transplanted to withstand 0.5-0.8% salt water, (mainly sodium chloride) strains and intermediate test materials; Jiangsu Province Institute of Soil and Fertilizer Academy of Agricultural Sciences screening of salt-tolerant rice varieties 80-85 in saline-alkali land yield per 300-400kg. We started in 1982, the identification of salt tolerance of soybean resources, the preliminary results are reported below.
