摘　　要：华北花岗片麻岩山地土壤严重退化,恶劣的土壤环境是该地区植被恢复的限制性因子。从加快土壤促成出发,利用试验区取回的岩石粉末,室内模拟肥料对岩石金属元素释放作用,进而找出土壤促成的最佳施肥措施。结果表明:利用缓释复混肥(HK)、生物有机肥(YJ)和微生物菌肥(SW)等3种肥料对Ca、K、Pb、Mg等金属元素释放量均有促进作用,但Ca、K元素有肥料溶液+岩石处理金属元素含量小于水+肥料对照处理的现象发生,可能由于金属元素与肥料中的某种元素产生了耦合反应或者是金属离子与溶液中CO2反应形成碳酸盐而又重新被固定。揭示3种肥料能够加快岩石风化速率,且以生物有机肥作用最强。The poor soil environment is the factor limiting to vegetation recovery in north granitic gneiss mountains.In order to find out the best fertilization measure to contribute to soil,it was simulated that fertilization had promoted the release of metal elements in rock in indoor with the rock powder from the test area.The results show that：three kinds of fertilizers-slow release fertilizer（HK）,bio-organic fertilizer（YJ）,microbial agent（SW）-promoted the release of metal elements such as Ca,K,Pb,Mg,but this phenomenon that the contents of metal elements with the treatment of fertilizer solution and rock powder was less than that with the treatment of water and rock powder took place at some treatment and determination time.The reasons might be due to metal elements and some kind of elements in fertilizer had taken place coupling reaction or metal elements and CO2 in solution had taken place reaction and formed carbonate and had been fixed again.It has revealed that three kinds of fertilizers speeded up the rate of rock efflorescence,and effect of bio-organic fertilizer was the best.
