在海拔高程为２２７４～２４２４ｍ的冷温半干旱黄土丘陵地区，荒坡人工翻坡水平台地上种植的一年生沙打旺植株的平均高度为１２．６ｃｍ，主茎明显，并能分生出一级分茎１枚。地上部分鲜草和风干草平均亩产量分别为３０８．１ｋｇ和８６．８ｋｇ，产出能平均为１４．７７×１０￣８Ｊ／亩，光能利用率为０．０８％。干草中粗蛋白质、粗脂肪、可溶性糖和粗纤维素平均含量分别为１６４、１６．６、１３３和２８３ｇ／ｋｇ。一年生沙打旺虽具耐寒、耐瘠薄和抗风沙的生物学特征，但在避风向阳和土壤水肥状况较好的坡地上，其生长发育较快，产草量亦较高。
In the cold and semi-arid loess hilly region with an elevation of 2274 ~ 2424m, the annual height of one-year-old plants planted on the horizontal platform of the artificial slope of the barren slope was 12.6cm. The main stems were obvious and the first stems could be divided 1 piece. The average yield per mu of fresh grass and dry hay on the ground were 308.1kg and 86.8kg, respectively, and the output averaged 14.77 × 10 ~ 8J / mu and the light energy utilization rate was 0.08%. The average contents of crude protein, crude fat, soluble sugar and crude cellulose in hay were 164, 16.6, 133 and 283 g / kg, respectively. Although the annual annual livethods are hardy, infertile and windbreak resistant, their growth and development are quicker and their grass yield is higher on sunny and sunny days.
