Abstract:

Correspondence analysis was used to analyze the nutritional value of 6 grasses species in Hulunber including crude protein (CP),crude fat (EE),crude fiber (CF),and crude ash (Ash). The results showed that there was a significant difference in the 6 grasses species and a certain correlation between nutrient content and forage grass. The contents of crude protein and crude fat of Elymus nutans ‘Aba’ (A) were the highest level (P<0.05),while those of Lolium multiflorum Lamk (D) were the lowest;Elymus dahuricus Turcz (P) had the highest content of adsorbed water (AW) and Elymus sibiricus Linn (L) was opposite;The crude fiber and crude ash of Elytrigia repens (L.) Nevski., (Y) were the highest and Agropyron cristatum×Agropyron desertorum ‘Hycrest Mengnong’ were the lowest. The contents of calcium or phosphorus was the highest in Elymus sibiricus Linn,and Agropyron cristatum×Agropyron desertorum ‘Hycrest Mengnong’ was the lowest in calcium,and Elytrigr Elytrigria (L.) Nevski. was the lowest in phosphorus.

摘要：

本研究运用对应分析方法对呼伦贝尔地区种植的6种禾本科牧草营养价值进行综合评定，结果表明：牧草品种间营养成分存在差异，且养分含量与品种间存在一定的相关性。‘阿坝’垂穗披碱草（Elymus nutans ‘Aba’）的粗蛋白与粗脂肪含量最高（P<0.05），多花黑麦草（Lolium multiflorum Lamk）最低；披碱草（Elymus dahuricus Turcz）的吸附水含量最高，老芒麦（Elymus sibiricus Linn）最低；偃麦草（Elytrigia repens（L.）Nevski.）的粗纤维和粗灰分含量最高，蒙农杂种冰草（Agropyron cristatum×A.desertorum ‘Hycrest Mengnong’）最低；老芒麦钙和磷的含量最高，蒙农杂种冰草钙含量最低，偃麦草磷的含量最低。
