摘　　要：[目的]在盐碱地施用脱硫废弃物,研究5种灌木在其上的生长情况。[方法]在施用脱硫废弃物进行改良的盐碱地栽植枸杞(Lycium chinense)、红柳(Tamarixramosissima)、紫穗槐(Amorpha fruticosa)、文冠果(Xanthoceras sorbifolia)和金银花(Lonicera japonica)5种灌木,并进行定期生长调查,比较其生长和生存状况。[结果]施用脱硫废弃物对红柳、枸杞和紫穗槐的生长量和成活率有明显的促进作用,而对文冠果和金银花的作用不显著。[结论]该研究可为改善宁夏银北地区盐碱地生态环境和提高造林成活率提供科学依据。[Objective]The research aimed to study the effects of applying desulphurized waste to the saline-alkali land on the growth of five kinds of shrubs.[Method]Five kinds of shrubs,Lycium chinense,Tamarix ramosissima,Amorpha fruticosa,Xanthoceras sorbifolia,Lonicera japonica,were planted on the saline-alkali land which applied desulfurized waste.Four growth indices（height,diameter,new shoots length and new shoot diamter）and suvival rate were investigated per month and compared them.[Result]The results indicated that the appliation of desulphurized waste obversily accelerated the growth and survive rate of Tamarix ramosissima,Lycium chinense and Amorpha fruticosa,but less impacted to Xanthoceras sorbifolia and Lonicera japonica.[Conclusion]The study can provide scientific basis for improving ecological environment and survival rate of afforestation in Yinbei Region of Ningxia.
