贮藏养分对牧草生长、越冬和再生极为重要，通过对几种牧草在年内多次刈割条件下的贮藏碳水化合物含量变化的研究，结果表明：随着刈割次数增加，贮藏碳水化合物含量下降，刈割次数越多，糖含量下降越多。不同的牧草下降幅度不同。Carbohydrate reserve is important for plant grow ,survive winter and regrowth.In this paper carbohydrare reserve of several grass in relation to herbage removal was studide.The results showed that as clipping times increase,carbohydrate content decreases.Different species of herbage have different decrease trends.国家自然科学基
