高冰草是高产优质牧草，为研究其耐盐性，进行了咸水发芽试验，幼菌及成年植株咸水灌溉试验。结果表明高冰草具有一定的耐盐性。用＜12g／L的咸水灌溉，对高冰草无明显的影响；用排碱渠低矿化度（5．85g／L）咸水灌溉高冰草，可获得较高的产草量。 Gao Bing Cao is a high-yielding and high-quality forage. In order to study its salt tolerance, a salt water germination test, a saline-water irrigation experiment on young and adult plants were conducted. The results show that the tall ice grass has some salt tolerance. Irrigation with <12 g / L saltwater had no significant effect on tall riparian grass. Higher irrigated grass could be obtained by irrigating tall riparian grass with low salinity (5.85 g / L).
