摘要
在大理州洱源县开展11个品种的紫花苜蓿试验,为期3年,期间在初花期刈割,测定株高、鲜草产量和干物质产量,同时测定牧草的粗蛋白、过瘤胃蛋白、酸性洗涤纤维、中性洗涤纤维等营养成分,通过比较得出秋眠级在6~8级的品种(赛迪7、WL440HQ、WL525HQ)表现出较高的鲜草产量和单位面积营养产量,比较适合在大理地区种植。
A trial involving 11 alfalfa varieties was conducted in Eryuan County,Dali Prefecture over a three-year period.The alfalfa were harvested at the initial flowering stage,during which plant height,fresh forage yield,and dry matter yield were measured.Nutritional components of the forage,including crude protein,rumen undegraded protein,acid detergent fiber(ADF),and neutral detergent fiber(NDF),were also analyzed.Comparative results demonstrated that varieties with fall-dormancy ratings of 6~8(Saidi 7)(WL440HQ,WL525HQ)exhibited higher fresh forage yield and nutritional yield per unit area,indicating their suitability for cultivation in the Dali region.
