呼伦贝尔地区6种禾本科牧草养分对应分析

Correspondence Analysis of Nutrient Contents in Six Gramineous Herbages in Hulunber

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。

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.
