分析 4种豆科牧草 9个不同半月龄的初水分含量和营养成分含量关系表明 ,4种豆科牧草的粗蛋白质含量与初水分含量间呈极显著正相关 (P <0 .0 1) ;粗纤维、酸性洗涤纤维、中性洗涤纤维、木质素含量与初水分含量间呈极显著负相关 ;粗脂肪含量与初水分含量间的相关程度则因牧草种类而异 ,分别表现出强正相关和中等程度正相关 ;而无氮浸出物含量与初水分含量的变数间则明显的表现出缺乏线性函数关系 ,两种变数的总变异中可以相互以线性关系说明的部分所占的比率较接近于 0 (0≤r2 ≤ 0 .4 4)。
The analysis of the relationship between the initial water content and nutrient content in four legume forages showed that there was a significant positive correlation (P <0.01) between the crude protein content and the initial water content of four leguminous pastures. There was a significant negative correlation between crude fiber, acid detergent fiber, neutral detergent fiber, lignin content and initial moisture content. The correlation between crude fat content and initial moisture content was very different And moderately positive correlation. However, there was a lack of a linear function between the variables without nitrogen and initial moisture content. The proportions of the total variability of the two variables, which can be explained by linear relationship, were closer to each other At 0 (0≤r2≤0.44).
