摘　　要：通过盆栽试验,对土壤采用添加25%土壤改良剂、以及添加12.5%改良剂和12.5%腐殖质的2种处理方式,研究Arkadolith土壤改良剂对冰草(Agropyron desertorum)、沙打旺(Astragalus huangheensis)和准格尔苜蓿(Medicago sativa cv "Zhonggeer")3种沙生牧草的生长特性的影响。结果表明,3种牧草中,植株高度、生长力、发芽力以及产量都较土壤改良前有所增强,沙打旺和准格尔苜蓿的生长状况要明显好于冰草。含有多种矿物成分的Arkadolith土壤改良剂不仅可以改良贫瘠土壤,提高土壤肥力,促进牧草的增产,而且还可以减少化学肥料的施用,降低成本,做到绿色环保,因此其具有广泛的推广意义。The paper studied the effects of Arkadolith Soil Amendment on three kinds of sandy pasture plant species,Agropyron desertorum,Astragalus huangheensis and Medicago sativa cv ＂Zhonggeer＂,in it＇s growth and soil characteristics in potted experiments by two different treatment：25% soil amendment into the sandy soil,12.5% soil amendment and 12.5% humus into the sandy soil.The results show that the growth characteristics of Astragalus huangheensis and Medicago sativa cv ＂Zhonggeer＂ are better than Agropyron desertorum.Arkadolith Soil Amendment which contains many kinds of mineral compositions could not only improve sandy soil fertilizer and increase the growth of pastures,but also decrease cost and environment-friendly.Thus it had a great value on extension.
