摘　　要：为解决吹填土快速脱盐与绿化问题,研究了区域改造配合微区调控方法对吹填土快速脱盐、培肥及绿化效果的影响。结果表明,对吹填土采用区域改造配合微区调控技术后,当年土壤脱盐率可达90%以上,土壤容重降低13.73%,有机质增加72.31%,碱解氮提高28.62%,有效磷增加27.90%,白蜡成活率可达到87%。采用区域改造配合微区调控方法,吹填土可达到当年改造当年绿化,实现快速绿化目的。To solve the problem of dredger fill fast desahing and greening, the method of regional transformation with micro regulation had been used in dredger fill to research the effect of fast desalting, fertility and greening. The results showed that after using regional transformation and micro-control technology, the soil desalination rate reached more than 90%, soil bulk density decreased 13.73%, organic matter,nitrogen and phosphorus increased 72.31%,28.62%and 27.90%, respectively, ash tree survival rate reached 87%. Based on the results, the method of regional transformation with micro regulation could achieve rapid desalting and greening in dredger fill
