摘要
通过对祁连山饲料灌木林树种的生物量调查分析得知:饲料灌木林地的地上生物总量是纯草场地上生物量的5～11倍,可食生物量是纯草场产草量的2倍以上;通过灌木枝叶化学成分分析结果,探讨了灌木树种的牲畜饲用价值,结果表明饲用价值的排列次序为:木旬子、高山绣线菊、小檗、沙棘、银露梅、锦鸡儿、金露梅。由此说明在祁连山区逐步发展饲料灌木林,是草场改良的一个重要方向。
The biomass of forage shrubs in Qilian Mountains was studied The results showed that the total biomass of it is as 5～11 times as meadow and feeding biomass is more than 2 times of meadow Meanwhile, feeding value of different shrub types have been studied by the chemical contents of leaves The orders of feeding value as following: Cotoneaster acutifolius、Spiraea alpina、Berberis diaphana、Hippophae rhamnoides subsp sinensis、Potentilla glabra、Caragana tangutica、Pontentilla fruicosa Therefore, developing the shrub land is an important measurement to improve the meadow in Qilian Mountains
