摘　　要：为了推广和利用饲用红花刺槐,对引种刺槐8个无性系对比试验林进行了植物学特性和营养分析。结果表明,红花刺槐与其他7个刺槐品种相比,其植物学指标均优于其他无性系。其主要饲料成分中粗纤维含量为12.8%,粗蛋白含量21.08%,粗灰分含量7.75%,其含量均高于大部分无性系。除粗纤维外,主要营养成分含量均达到或超过优良牧草的标准。红花刺槐的营养元素Cu、Fe、Mn、Zn的总量是773.209 3 mg/kg,为8个无性系中最高,比普通刺槐的总量高348.402 2 mg/kg。但具体到每种营养元素的含量,各无性系之间互有差异。This experiment analyses nutritional speciality of eight clones of introduced black locust. The result showes that botanical speciality of Robinia pseudoacacia var. decaisneana is better than that of other clones. The crude fibre content is 12.8%, and the crude albumen content is 21.08%, the ash content is 7.75%. The result is higher than that of others. The mostly feeding content either reaches or exceeds the criterion of eminent pasture besides the crude fibre, The total content of Cu, Fe, Mn, Zn of Robinia pseudoacacia var. decaisneana is 773.2093 mg/kg, which is the highest among the eight clones, and is 348.4022 mg/kg higher than that of common black locust. But nutritional element content of each clone exists some differences each other.
