为了筛选耐盐大豆品种，针对大庆地区土壤特点，选用垦丰10号和安达农家种2个大豆品种，用不同浓度的NaHCO3进行盐胁迫试验。结果表明：随着盐浓度的增加幼苗根系活力、根系体积和种子活力逐渐降低，而干重随盐浓度增加无明显变化，这说明不同土壤含盐量对大豆种子萌发及幼苗生长有显著影响。2个品种除了根系活力没有显著差异外，垦丰10号在幼苗根系体积、幼苗干重和种子活力上都显著高于安达农家种，说明不同品种的耐盐性也存在显著差异。

In order to screen out salt-tolerant soybean varieties ,according to soil property of Daqing area ,two varieties of soybean Kenfeng 10 and farmhouse soybean of Anda were intimidated by NaHCO3 of different dos-ages .The results showed that roots activity ,roots volume and seed vigor were reducing with the increasiag dos-age of NaHCO3 ,but there’s no distinct change of dry weight ,which explained that there's significant effect of soil with different salt content on germination and seedling growth .Kenfeng 10 was significantly higher than farmhouse soybean of Anda on roots volume ,dry weight and seed vigor ,except that there’ s no significant difference on roots activity ,that's explained that different varieties had different salt-tolerance property .
