| 摘 要： | 对生长在黔西南州岩溶区的27种饲料灌木常规营养成分及元素作测定,对结果进行灰色关联度及相关性分析,结果表明:构树所含营养元素综合评价为最好,以下依次为青刺尖牛王刺光腺合欢马棘小构树火棘白刺花紫穗槐刺梨。碳、氮、钙元素与饲料常规营养成分相关性最大,其次为钾、磷、硒、铁、锌,其多数与饲料的粗蛋白、粗脂肪、灰分呈正相关,与粗饲料的粗纤维呈负相关。 |
| 关 键 词： | 饲料灌木 矿质元素 营养成分 灰色关联度分析 |

| Abstract: | Though the growth and reproduction of plants are restricted in karst areas where the environment is characterized by calcium-rich and water-lacking features, the local shrubs are adapted to that environment. It is feasible to use local shrubs to develop ecological fodder for animal husbandry. Southwestern Guizhou which is rich in fodder shrub resources is selected as the studied area. As nutrient absorption capacity of plant can be taken as an indicator for its adaptability to the environment, the nutriment... |
