水稻不同品种耐盐限度研究初报

了解水稻不同品种的耐盐限度,对于盐渍土区稻作生产的持续、稳定发展有着重要意义。试验表明,土壤全盐5.94g/kg时,盐粳68、花粳8、辽粳294和盐粳34的发芽率均不低于90%。花粳15分蘖期最高耐盐为14g/kg,盐粳68拔节孕穗期最高耐盐为17g/kg,盐丰47-6成熟期最高耐盐为12g/kg。12个供试水稻品种,其中盐粳68、花粳8、辽粳9和92-71耐盐能力强;花粳15、抗盐100、盐丰47-6、辽粳294、盐粳34和盐粳31耐盐能力次之。

Preliminary study about the haloduric limitation on different rice variety

It had important meaning to understand the haloduric limitation on different rice variety which to steady and persistent development about rice production of salinized zone.The test indicated that when the soil total salt was 5.94 g/kg,the germinating capacity of Yanjing-68,Huajing-8,Liaojing-294 and Yanjing-34 were all exceed 90%.The highest salt tolerance of Huajing-15 in stooling stage was 14 g/kg,the highest salt tolerance of Yanjing-68 in booting stage was 17 g/kg,the highest salt tolerance of Yanfeng-47 in autumn was 12 g/kg.Among the 12 varieties,Yanjing-68,Huajing-8,Liaojing-9 and 92-71 had better salt tolerance,secondly were Huajing-15,Kangyan-100,Yanfeng47-6,Liaojing-294,Yanjing-34 and Yanjing-31.
