| 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(P0.05),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 of Nutrient Contents in Six Gramineous Herbages in Hulunber |
| |
| 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. |
