紫穗槐,又名棉槐、椒条、紫翠槐、紫花槐,豆科多年生落叶灌木,原产北美,引入我国后广泛分布于东北、华北,以至广东、广西、云南各地,垂直分布于1000米以下。它生长迅速、一般二年开花结实。 一、适应性强 紫穗槐根系发达,枝叶茂密,适应性强,耐干旱,耐寒冷,耐盐碱,耐水湿,耐瘠薄,在水土流失严重的荒坡、荒沟均生长良好,在湿润的沟谷生长更好。吉林省水土保持科学研究所仇家沟试验场,把紫穗槐栽于水土流失严重的黄土荒坡上,成活率达到96%。它对沼泽地、盐碱地、洼地也都适应,在摄氏零下25度冻不死,年降雨量213毫米也能生长。
Amorpha fruticosa, also known as cotton acacia, pepper, purple Trameau, purple Sophora japonica, Legume perennial deciduous shrub, native to North America, after the introduction of our country is widely distributed in the northeast, north China, as well as Guangdong, Guangxi, Yunnan all over, vertically distributed in 1000 meters below. It grows rapidly, generally two years flowering strong. First, the adaptability of Amorpha fruticosa root developed, strong foliage, strong adaptability, drought resistance, cold resistance, salt tolerance, water wet, barren infertility, severe erosion in the barren, wilderness are good growth in the wet Gully grows better. Jilin Province Institute of Soil and Water Conservation Choujiagou test site, the Amorpha fruticosa planted in soil erosion on the loess plateau, the survival rate of 96%. It also adapts to wetlands, saline soils and depressions, freezing at temperatures below minus 25 degrees Celsius and growing at an annual rainfall of 213 mm.
