| 摘 要： | 通径分析表明,苜蓿干草在调制过程中含水量与粗蛋白质之间的相关关系主要是通过中性洗涤纤维(NDF)和叶片损失率的间接影响产生的;NDF与粗蛋白质的相关关系,直接作用和通过叶片损失率的间接作用各占50%,并且通过含水量所起的作用为正效应;叶片损失率与粗蛋白质含量的相关关系,主要是直接作用(占56.0%)和通过NDF的间接作用(占54.5%)所引起的. |

| Abstract: | During Medicago sativa hay cured, the correlation between moisture and crude protein was mainly produced by indirect relation of NDF and loss ratio of leaf. The direct contribution of NDF to crude protein was about 50%, with the indirect contribution produced by loss ratio of leaf was shown to be also 50%, further the indirect contribution of moisture was shown to be a positive function. The direct and indirect correlation of loss ratio of leaf and crude protein was 56.0% and 54.5%, respectively. |
