太行山山地草原几种主要牧草的营养成分分析

Analysis on the Nutrient Composition of the Some Main Species of Herbages in the TiaHanshan Mountain Grassland

本文研究了太行山山地草原几种主要牧草的营养成分。结果表明,每种植物的还原糖、总糖、粗脂肪、粗蛋白质和总磷的百分含量之总和的平均数是:硬质早熟禾(30.72％)>亚柄苔草(28.21％)>多叶隐子草(25.94％)≈披碱草(25.14％)>紫羊茅(23.12％)阿尔泰针茅(21.40％)。其中,总糖、粗脂肪和粗蛋白质等三种主要营养成分的百分含量之总和的平均值是:硬质早熟禾(28.62％)>多叶隐子草(25.21％)>披碱草(23.91％)>亚柄苔草(21.78％)≈紫羊茅(21.77％)>阿尔泰针茅(20.66％)。硬质早熟禾、多叶隐子草和披碱草是优良牧草。

. The paper is a report of the analysis on the nutrient compositions of the some species herbage in the monutain grassland of the TaiHang mountain. The results of the experiment turued out to be clear that the meat of the total of the reducing suger(%) + total sug-er(%)+f crude fat(%)+crud protein(%) + total phosphorus(%) was Poa sphondyiodes(30.72%)>Carex subpediformis (28.21%) > Cleistogens polyphylla ( 25.94% ) ≈ Clinelymus dahuricus ( 25.14% )> Festuca rubra ( 23.12% ) >Stipa krylovii ( 21.40% ). The mean of the total o'f the total sugar % +crude fat%+crude protein% was P. sphondy-lodes (28.62% )>C. polyphylla ( 25.21% ) >C.dahuricus ( 23.91% ) > C. subpediformis(21.78%)≈F. rubra(21.77%)> S. krylovii(20.66% ) . The P. sptondylodes, C. polyphylla and C. dahuricus are good herbages.
