| 説明 | Introduced, warm-season, annual to short-livedperennial, prostrate to sprawling legume. Stems are hairless to densely bristly. Leaves arepinnate, with 20-50 leaflets, each 3-15 mm long. Flowerheads consist of clusters of 3-10 yellow pea-likeflowers in the leaf axils. Pods are divided into 3-7 segments and covered in dense soft or stiffly erect hairs. Flowers throughout the growing season. A native of North America, it is sown for grazing or as an orchard ground cover. Best suited to soils with a pH(Ca) greater than 5, an annual rainfall of more than 1000 mm and where moisture is retained. It is not very persistent on poorcountry. A palatable and high quality feed, it producesmoderate yields under good conditions. Not very drought tolerant and is susceptible topowdery mildew. Responds strongly to phosphorus applications, but will tolerate low fertility (although much loweryielding). Tolerates heavy grazing and benefits from levels of grazing which reduce shading by grasses. |
