沙打旺(Astragalus adsurgens Pall.)为豆科黄芪属植物,我们从1974年以来引种、观察、鉴定,证明该植物具有耐寒、耐旱、生长旺盛、产草量高、适口性好等特点,适宜于在风沙、干旱、低温地区栽培。为了探求沙打旺生长发育同外界环境温度因子的关系,为大面积推广种植提供科学依据,特将我们几年来对沙打旺进行引种观察的资料整理、分析如下。 Astragalus adsurgens (Astragalus adsurgens Pall.) Is a legume Astragalus plant, we introduced, observed and identified since 1974, and proved that the plant has characteristics of cold tolerance, drought tolerance, vigorous growth, high yield of grass and good palatability, Suitable for wind and sand, drought, low temperature cultivation. In order to explore the relationship between the growth and development of Astragalus and environmental factors, provide a scientific basis for large-scale popularization of planting, especially the introduction of sand weeds for several years to organize the introduction of information collation as follows.
