阔荚合欢(Albizia lebbeck)在澳大利亚昆士兰普遍用作遮荫树,它也是一种潜在的牧草资源。本文对阔荚合欢的立地条件、生长情况和产量等进行了综述。阔荚合欢可在广泛环境中生长,它易长根瘤,叶片是适口性很好的高蛋白饲料。可以断言,阔荚合欢将成为热带地区的一种重要饲料作物,同时在盐渍地区也将具有特殊的开发价值。 Albizia lebbeck, commonly used as a shade tree in Queensland, Australia, is also a potential source of pasture. In this paper, the site conditions, growth and yield of Acacia crassicarpa were reviewed. Acacia can grow in a wide range of environments, it is easy to grow nodules, leaf palatability is good high-protein feed. It can be asserted that broad-leaved Acacia will become an important feed crop in the tropics and will also have special development value in salted areas.
