Abstract:: 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.
