摘　　要：通过碱茅草新品系耐盐试验，测定出碱茅种子对碳酸钠、硫酸钠及氯化钠的耐盐能力：１５℃恒温，碳酸盐２．０％时发芽率３０％；硫酸盐１．６％时发芽率３３％；氯化物１．０％时发芽率３４％。与原始野生种对比，种间差异显著（Ｐ＜０．０１）。Through the salt-tolerant test of the new strain of alkaligrass,the salt- tolerant ability of its seed toNa2CO3,Na2SO4 and NaCl was determined.The germination rate is 30%in 2%Na2CO3,33%in 1.6%Na2SO4 and 34%in 1.0%NaCl at constant temperature of 15℃,In comparison with primitive wild speci-es,the difference between species was significant(P<0.01).
