【摘要】 １９９１～１９９３年通过对８个混播组合处理的相对干物质产量的增高、豆禾比例稳定性以及对飞机草的抑制力等指标进行的观测结果表明，大叶千斤拔与多年生落花生能与臂形草混播持久，并能抑制飞机草的侵袭，同时可使草场中饲草的粗蛋白质含量由单播５．６％提高到混播的１２．２％。更多还原

【Abstract】 It has been reported that the study on application of an effective way of controlling the weed, Feijicao (Chromolaena odorata R.M. King and H. Robinson) is to plant Signalgrass (Brachiaria decumbens Stapf cv. Basilisk) on the pasture, but the artificial grassland solely based on Signalgrass planting is not only low in nutrient contents, but also tends to become less productive over long years, then would deteriorate entirely and noxious weeds will come back again. For the aim of keeping Signalgrass dominance constantly and raising the productivity of the pasture, from 1991 to 1993, we conducted trials continuously by using 8 legume - Signalgrass combinations in mixture planting. The result indicated that two legume species, Flemingia macrophylla (Willd.) Merr. and Arochis pintoi cv. Amarillo can be planted well with Signalgrass for a long time to fight against weeds and raise the crude protien content in the pasture from 5.6% to 12.2%.更多还原
