通过引种,筛选,用大翼豆 (Macroptilium atropur purum)和狗尾草(Setaria sphacelata)混播建立人工草场有许多优越性。两者都有发达的根系,耐旱,耐瘠,生态学上有较好的配合力。一旦建成人工草场,可连续用好几年,既可割草又可放牧。割草最好在5～10月进行,间隔45天左右,割四次,每公顷可年获混合鲜草25.7吨,比天然草坡地高20倍以上。混合牧草可饲养牛、羊,兔等各种家畜,也可喂养草鱼(Ctenophar yngodon idellus)。混播草地还能保持水土,有助于土壤有机质积累和肥力提高。
There are many advantages to establishing artificial grass pastures by introducing, screening, mixing with Macroptilium atropur purum and Setaria sphacelata. Both have developed roots, drought, barren, ecologically better co-operation. Once built artificial grassland, can continue for several years, both grass and grazing. Mowing is best carried out in May to October, about 45 days apart, cut four times per hectare can be mixed annual fresh grass 25.7 tons, more than 20 times higher than the natural grass slope. Mixed forage can feed cattle, sheep, rabbits and other livestock, but also feed grass carp (Ctenophar yngodon idellus). Mixed grassland can also maintain soil and water, contribute to the accumulation of soil organic matter and fertility.
