摘要
为了比较杂交构树不同高度及不同部位的营养价值,试验对高1m、1.5m和2.0m杂交构树全株嫩苗以及高1.5m和2.0m的杂交构树茎、叶营养成分分别进行测定。结果表明,杂交构树全株嫩苗的CP含量随着高度的增加显著降低,CF、NDF、ADF含量随着高度的增加显著增高(P<0.05),全株嫩苗作为饲料利用适宜的刈割高度为1.0~1.5m左右,粗蛋白含量为20.5%~23%;叶中的CP、CA、EE、Ca含量显著高于茎,CF、NDF、ADF含量显著低于茎(P<0.05),饲料利用叶优于茎。
In order to compare nutritive value in different height and different parts of hybrid broussonetia papyrifera, the contents of nutrients in whole plants with a height of 1m, 1.5 m, 2.0 m, stems and leaves with a height of 1.5 m, 2.0 m were measured respectively. The results show that the CP content decreased and the CF, NDF, ADF content increased with the increase of height of whole plants（P〈0.05）, The suitable cutting height of the whole seedling was about 1.0～ 1.5 m, and the CP content was 20.5%～23%. The CP, CA, EE, Ca content of leaves were significantly higher than stems, and CF.NDF. ADF were inverse, and leaves were superior than stems for feeding.
