摘要：
Neutral black soil was mixed with strong saline-alkali soil in different weight ratios,then physiological indexes during seed germination and seedling growth in soil of different ratios and the corresponding leaching liquor treatments were observed to explore effect of saline-alkali stress on oat seed germination and seedling growth,and analyze tolerance of oat to saline-alkali soil.The results showed that germination ability of oat seeds reduced with the increasing salinealkali stress,salt injury index increased and seedling growth was inhibited.Effect of different saline-alkali stresses on germination ability of oat seeds showed difference,and effect of leaching liquor treatment on oat seed germination was stronger than that of soil treatment.
