华北花岗片麻岩山地土壤促成技术研究——室内模拟肥料对岩石金属元素释放作用I
Study on Soil Facilitation Technology to Granite and Gneiss Mountain in North China——The Effect of Metal Element Release from Rock by Indoor Simulation Fertilizers I
摘要
Abstract
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.关键词
