| 説明 | Native, warm-season, perennial, tufted, erect to spreading grass to 60cm tall. Stem bases are hairy, thickened and knotted. Nodes are covered with soft fine hairs, with a few long hairs.Widespread throughout the Plains on lighter soils (sandy loam to clay loam); rarely on clays. More common on fertile soils where moisture is high. Usually found under tree canopies and where it is protected from grazing around fallen timber. Very drought tolerant and slightly frost tolerant. Moderate to high grazing value. Digestibility ranges from 35-56% – from one trial (only) at Cobar. Crude protein is 11-15.5%. Usually only a minor component of pastures. Dry matter yields are low, but it is highly palatableand regarded as useful forage even after it has hayed off. On poor soils it forms a slender wiry plant, but forms a dense leafy tussock on moister, more fertile sites. The bulk of growth is produced in summer andautumn, but it will produce a green pick throughout the year in all but the driest times. Persists best under rotational grazing. It rapidly regenerates when stock are excluded after heavy grazing, as its buds are below ground level andprotected from damage. |
