紫穗槐又称鼬获、棉槐,是一种多年生的豆科灌木,高的可达9尺,生长快,适应性强,耐旱、耐涝在轻度盐碱滩地也能生长,只是耐寒性能稍差,是在荒山和沙荒上。造林良好树种。在我国种紫穗槐较早的地方有东北的东南部、华北和山东一带,解放以后,青海省民和、乐昌、循化、贵德等县和陕西延安专区等比较高寒地区都作了引种驯化试验,初步效果良好,南方湖南、江西等地也都在大量进行了繁殖。紫穗槐的用途很广,经济价值也很高,其主要用途有:1.它有保持水土,改良土壤的作用。它的根系发达,生长4年后主根长达3尺,侧根分布范围最长达1丈2尺以上,因此具有良好的固土蓄水效能,根部又长有很多根瘤,可以制造氮肥,在农田隙地、地埂边坡
Amorpha fruticosa, also known as ferret, cotton acacia, is a perennial mesquite, up to 9 feet high, fast growth, adaptability, drought tolerance, waterlogging can also grow in mild saline beach, but Cold hardiness is a bit poor, is in barren hills and sand shortage.
