紫穗槐是一种多年生的落叶灌木,枝叶繁茂,根系发达,河、沟、渠边种上它,上挡雨水淋涮,下固河坡泥土,从而可增强河坡的防冲能力,保持水土。它的叶面蒸腾量大,每平米叶面积在12小时内蒸腾达8～9斤水、能起到生物排水防渍的效果。重盐地营造紫穗槐林结合冲洗灌溉或匡格保蓄雨水淋盐,二、三年即可把土壤盐分降到1‰以下;其落叶和根瘤可以培 Amorpha fruticosa is a perennial deciduous shrub with lush foliage, well-developed root system, the river, ditch and canal edge planted on it, dripping rainwater and rinsing the soil of Xiaoganhe River so as to enhance the anti-erosion ability of the river slope and maintain Soil and water. Its large amount of leaf transpiration, leaf area per square meter in 12 hours of steaming up to 8 to 9 pounds of water, can play the biological effect of anti-flooding. Heavy salt to cultivate Amorpha fruticosa irrigation combined with irrigation or Kuangang save rain pouring salt, two or three years to soil salt below 1 ‰; its leaves and nodules can be cultivated
