摘要
摘要本区地处亚热带。常见野生饲用植物以多年生禾草和常绿阔叶树数量最多。后者的粗蛋白质含量虽高于前者,但由于适口性较差,所以饲料价值低于前者。一般而论,本区草丛草地比温带干草原上的多年生禾本科牧草营养价值要低。此外,多年生禾草的粗蛋白质含量随海拔增高而增加,粗纤维恰好相反。
ABSTRACT This region is located at the subtropics. The amount of perennial grass family and broadleaved evergreen tree in common wild forage plant is the largest. Crude protein content of the latter usually is larger than that of the former, but it′s forage value is smaller, because of its low platability In general, nutritive value of perennial grass in subtropical grass-heath grassland of this region is smaller than in steppe of temperate zone. Moreover. when altitude rises, crude protein content of perennial grass increases and crude cellulose content becomes smaller.
