摘要
通过对青海天然草地牧草4大类主要营养成分进行分析,结果表明:青海天然草地牧草具有粗蛋白质、粗脂肪、无氮浸出物含量高,粗纤维含量低,即"三高一低"的特点。与全国同类型草地牧草营养成分相比,粗蛋白质高2.61个百分点,粗脂肪高0.4个百分点,无氮浸出物高4.92个百分点,粗纤维低20.42个百分点。
We analysed 4 types major nutrients of Qinghai natural grassland and the results showed that: the characteristics of grass main include crude protein,crude fat,high content of nitrogen free extract,low crude fiber content that is the "three high and one low".Compared with the National Forage nutrient crude protein higher 2.61 percentage points,crude fat higher0.4 percent,nitrogen-free extract higher4.92 percent and crude fiber lower 20.42 percent.
