摘　　要：[目的]明确湖南省草地豆科植物的营养价值。[方法]采集17份开花期豆科植物种质资源,测定分析粗蛋白(crude protein,CP)、干物质(dry matter,DM)、粗脂肪(ether extract,EE)、粗纤维(crude fiber,CF)、粗灰分(crude ash,Ash)、无氮浸出物(nitrogen free extract,NFE)等营养成分含量,并运用灰色关联度法进行营养价值综合评价。[结果]从营养成分含量来看,17份种质的DM含量为10.49%~50.79%,CP含量为7.49%~19.17%,EE含量为0.82%~4.60%,CF含量为23.76%~42.57%,Ash含量为5.33%~15.54%,NFE含量为37.50%~50.72%。铁马鞭(Lespedeza pilosa)的DM含量(50.79%)最高、Ash含量(5.33%)最低,小巢菜(Vicia hirsuta)的CP含量(19.17%)最高,合欢(Albizia julibrissin)的EE含量(4.60%)最高,赤豆(Vigna angularis)的CF含量(23.76%)最低,锦鸡儿(Caragana sinica)的NFE含量(50.72%)最高。17份豆科植物的等权关联度、加权关联度排名基本相同,其中合欢(0.8596、0.8644)、小巢菜(0.7885、0.7984)、赤豆(0.7514、0.7733)、铁马鞭(0.7417、0.7336)、锦鸡儿(0.7371、0.7546)、褶皮黧豆(0.7362、0.7455)综合排名比较靠前。[结论]综上所述,湖南省草地17份豆科植物开花期种质资源中合欢的营养品质最好,小巢菜、赤豆的营养品质次之。[Objective]To clarify the nutritional value of leguminous plants in Hunan grasslands.[Methods]Seventeen germplasm resources of leguminous plants at the flowering stage were collected.The contents of crude protein(CP),dry matter(DM),ether extract(EE),crude fiber(CF),crude ash(Ash),and nitrogen-free extract(NFE)were determined and analyzed.The nutritional value was comprehensively evaluated using the grey relational analysis method.[Results]The analysis of nutritional composition revealed that the DM content of the 17 germplasms ranged from 10.49%to 50.79%,the CP content from 7.49%to 19.17%,the EE content from 0.82%to 4.60%,the CF content from 23.76%to 42.57%,the Ash content from 5.33%to 15.54%,and the NFE content from 37.50%to 50.72%.Lespedeza pilosa exhibited the highest DM content(50.79%)and the lowest Ash content(5.33%);Vicia hirsuta had the highest CP content(19.17%);Albizia julibrissin showed the highest EE content(4.60%);Vigna angularis had the lowest CF content(23.76%);Caragana sinica had the highest NFE content(50.72%).The rankings based on equal-weight and weighted grey relational degrees were largely consistent,with Albizia julibrissin(0.8596,0.8644),Vicia hirsuta(0.7885,0.7984),Vigna angularis(0.7514,0.7733),Lespedeza pilosa(0.7417,0.7336),Caragana sinica(0.7371,0.7546),and Mucuna lamellata(0.7362,0.7455)ranking higher overall.[Conclusion]In summary,among the 17 leguminous plant germplasms at the flowering stage in Hunan grasslands,Albizia julibrissin exhibited the best nutritional quality,followed by Vicia hirsuta and Vigna angularis.
