摘要
测定了Na2CO3胁迫下五种禾本科牧草苗期的植株存活率、生物量、生长胁迫指数等生长指标与其耐盐性的关系。结果表明:五种牧草的存活率(浓度>0.5%)、鲜重与干重均随着Na2CO3胁迫浓度的升高而降低,草种间耐盐性差异显著,其耐盐性强弱顺序是野大麦>披碱草>肥披碱草>老芒麦>无芒雀麦。
The relations of five kinds of gramineous grass growing indexes,such as surviving rate,biomass,growth stress index etc with their salt tolerance were studied.The result indicated that their surviving rate,fresh weight and dry weight decreased with the increasing of Na_2CO_3 concentration.The difference of their salt tolerance among these grass species is significant,the order of their salt tolerance was Hordeum brevisubulatum>Elymus dahuricus>Elymus excelsus>Elymus sibiricus>Bromus inermis.
