不同利用强度对草甸草原牧草营养品质的影响

The Influence of Different Use Strength on the Herbage Nutritional Quality in Meadow Steppe

采用单因素重复设计探讨锡林郭勒草甸草原不同草地利用强度下天然牧草的响应。结果表明:不同利用强度对粗蛋白质产生影响主要发生在对照和重度利用;随利用强度增加,粗纤维含量降低,粗灰分含量上升,粗脂肪呈先增加后降低趋势;含水量以对照和轻度利用处理较高,中度利用和重度利用处理较低。

Meadow steppe communities in different degradation degree in Xilinguole were investigated in 2006 and 2013.The single factor repeat test design was made to study the response of grasses to different use strength.The results showed that the influence of different use strength on crude protein was mainly occurred in CK and heavy use;the content of crude fiber was decreased with the increase of use strength,the content of ash was decreased with the increase of use strength,while the crude fat increased first and then decreased;CK and light use had the higher water content,while the middle use and heavy use had the lower water content.
