摘　　要：对临泽盐渍化土地栽培的鲁梅克斯K - 1杂交酸模 ,进行了植物学特征、耐盐碱、抗寒性、营养价值、根系及土壤含盐量等性状的分析 ,发现鲁梅克斯K - 1杂交酸模在含盐量 1 15 %土壤环境生长良好 ,其根组织能耐盐碱 ,且 0～ 5cm土层含盐量可下降 37 0 3%～ 5 0 5 8% ,年可收获优质干草 12 .4t hm2 。Rumex K-1 was introduced and cultivated in saline land of arid areas in Linze county. The botanical features, saline and alkaline tolerance, cold resistance, nutritive value, salinecontent of root system and soil were analyzed.The results showed that Rumex K-1 grew better on a soil layer of 0～50 cmwith≤1.15% salinecontent,reduced the saline content of 0～50 cm soil by 37.03%～50.58% and was harvested dry grass of 1.24×10 4 kg/hm 2per year. Rumex K-1 wasapotential grass to exploit andextend.
