摘要
为了研究榆林市风沙区6种主要灌木(柠条、紫穗槐、杨柴、花棒、沙打旺、沙柳)开花期的营养成分,通过对CP、DM、NDF、ASH、Ca和P进行分析,与苜蓿进行对比,判断其营养价值。结果表明:柠条(1年)的CP、ASH和Ca含量显著高于其他灌木(P<0.05),分别为:15.02%、7.07%和3.08%;沙打旺的CP、Ca和P含量显著高于其他灌木(P<0.05),分别为:15.23%、2.07%和0.211%;杨柴和沙柳(1年)的CP含量显著低于沙打旺、柠条(1年)和紫穗槐(P<0.05),分别为:11.89%和11.40%;但Ca含量显著高于花棒、柠条(多年)和沙柳(2年)(P<0.05),分别为:1.85%和2.02%。柠条(多年)、沙柳(2年)和花棒的营养成分含量显著低于其他灌木(P<0.05)。
The paper aims to analyze the contents of CP, DM, NDF, ASH, Ca and P of 6 shrubs（Caragana korshinskii Kom., Amorpha fruticosa Linn, Hedysarum leave Maxim., Hedysarum scoparium Fisch. et Mey.,Astragalus adsurgens Pall., Salix cheilophila Schneid.） at the flowering stage in sandy area of Yulin, and took Medicago sativa as the control to determine the nutritional components. The results showed that： the contents ofCP, ASH and Ca of 1-year-old C.korshinskii were 15.02%, 7.07% and 3.08%, which were higher than that ofthe other shrubs（P〈0.05）; the contents of CP, Ca and P of A. adsurgens were 15.23%, 2.07% and 0.211%,which were higher than that of the other shrubs（P〈0.05）; the contents of CP of H.leave and 1-year-old S.cheilophila were 11.89% and 11.40%, which were lower than that of A. adsurgens, 1-year-old C.korshinskii and A. fruticosa（P〈0.05）, but the contents of Ca of H.leave and 1- year- old S.cheilophila were 1.85% and2.02%, which were higher than that of H.scoparium, C.korshinskii（perennial） and 2-year-old S.cheilophila（P〈0.05）; the nutritional components of C.korshinskii（perennial）, 2-year-old S.cheilophila and H.scoparium, were lower than that of the other shrubs（P〈0.05）.
