新型饲草大叶枸的生物学特性和营养价值评定研究

Study on Biological Characteristics and Nutritional Value of New Type Forage Grass Big-leaf Mulberry

对新型木本植物大叶枸的生长速度、鲜草产量、营养成分等进行了观测。结果表明:大叶枸的生长速度快、再生能力强,每年每公顷可产鲜草207.0 t;大叶枸叶片的粗蛋白含量为24.9%,其可饲用部分的粗蛋白、ADF、NDF和钙含量分别为23.0%、25.6%、43.4%、1.41%,但其磷含量较低。

The growth rate,fresh yield and nutritional composition of a new-type woody forage plant,big-leaf mulberry,were studied in this paper.The results indicated that this plant had speedy growth rate and strong regeneration ability,and it could produce 207.0 t fresh grass annually per hectare;the crude protein content in the leaves of big-leaf mulberry was 24.9%,the contents of crude protein,ADF,NDF and Ca in its edible part were 23.0%,25.6%,43.4% and 1.41%,respectively,but its phosphorus content was low.
