摘要：华北花岗片麻岩山地土壤严重退化,恶劣的土壤环境严重限制了该地区的植被恢复。为了扭转这种不利因素,探寻加快土壤促成的方法,本研究利用试验区取回的岩石粉末,室内模拟3种不同肥料4种不同处理梯度对岩石金属元素的释放作用,进而找出土壤促成的最佳施肥技术。通过连续50 d对金属元素的释放量观测,结果表明:3种肥料在不同处理梯度上对Na、Fe、Cr、Al等金属元素释放量均有促进释放作用,揭示了3种肥料能够加快岩石风化速率,且以生物有机肥作用最为理想,为华北花岗片麻岩山地植被恢复和退耕还林工程的顺利实施提供技术支持。
Soil seriously degenerates in North China granitic gneiss mountains,poor soil environment seriously limits the vegetation recovery in this region.In order to reverse the negative factor,to explore ways to speed up the soil development,the rock powder from the test area was brought back to laboratory,and it was simulated that three kinds of different fertilization under four kinds of different treatment had promoted the release of metal elements for finding out the best fertilization measure to contribute to soil.Through 50 days continuous observation to release of metal elements,the results showed that： three kinds of fertilizers under different treatments have advancement effect on the release of metal elements such as Na,Fe,Cr and Al.It showed that three kinds of fertilizers could speed up the rate of rock efflorescence,and effect of bio-organic fertilizer was the best.It will provide technical support for the vegetation recovery and successful implementation of Grain for Green Project in North granitic gneiss mountains.
