| 摘 要： | 在人工放牧地上研究了鸡脚草、牛尾草体内糖分含量的积累与放牧后再生速度、温度的关系；糖分含量的积累与化学成分含量的关系等。研究结果表明：两种牧草的茎叶部和根部糖分含量的积累均随着温度升高，放牧后再生速度加快而减少；随着温度降低，再生速度缓慢，糖分含量积累显著增加。两种牧草茎叶部糖分含量均高于根部。鸡脚草茎叶部糖分含量略高于牛尾草，而牛尾草根部糖分含量高于鸡脚草。两种牧草体内糖分含量的积累与化学成分含量尚未发现明显规律性的变化。根据研究结果提出了合理利用人工草地的建议。

| Abstract: | In this paper,the relationship between the sugar accumulation and the rate of regeneration,temperatureafter grazing,and between the suger accumulation and the chemical component of Dactylis glomerata and Festuca pratensis on the artificial grassland were studied.The results showed that the sugar accumulationdecreased with the temperature rising and increase of the rate of regeneration after grazing in stems andleaves as well as in roots of two grasses. The suger accumulation obviously increased with the reduce of thetemperature and the rate of regeneration. The suger content in slems and leaves is more than in roots of twograsses. The suger content in stems and leaves of Dactylis glomerata is little higher than Festuca pratensis,but in roots of the former is less,than the latter. The obviously regular change between the sugeraccumulation and chemical component of two grass,es was not found. According to the research results,wepointed out the suggestion about rational utilizing the artificial grassland. |
