摘要
研究分析了放牧条件下短花针茅荒漠草原植物贮藏性碳水化合物的变化。结果表明 ,不同放牧方式下植物贮藏性碳水化合物含量不尽相同 ,季节性波动较大。还原糖比总糖变化剧烈 。
The carbohydrate seasonal dynamic of plants under grazing stress in Stipa breviflora desert steppe were analyzed. The results showed that the carbohydrate contents of plants under different grazing stress weren't the same all the time, and the seasonal dynamic of carbohydrate was significant. The dynamic of reducing sugar was severer than total sugar. The relationship between and plants reducing sugar growth was closer than that of total sugar.
