【摘要】 研究了微波处理对过量施肥导致污染的土壤的恢复作用。利用自行研制的微波工程车对选定的成都郊区某菜地中过量施肥土壤进行修复。微波处理6min后发现土壤的活性发生了变化:对比处理前后土壤中种植的相同植物的状态,发现未被处理过的土壤样本的植物更容易死去。通过自动凯氏定氮仪以及分光光度计分析表明,微波照射一定时间后的土壤中全氮和全磷的含量明显下降。微波修复为过量施肥土壤污染的修复提出了一种更便捷、彻底的修复方案。更多还原

【Abstract】 Microwave recovery of the polluted soil caused by too much fertilizer is presented in this paper.Using a micro-wave tackle,the polluted soils selected from vegetable field in the suburb of Chengdu are treated for about 6 minutes and 3 minutes respectively.Green foliages are planted in the soil with and without microwave treatment to investigate the activity of the soil.It is observed that the foliages are easy to die in the soil without microwave treatment. And through Auto-Kjeldahl’s Apparatus and spectrophotometer,it is indicated that the concentrations of N and P in the soil after microwave treatment are obviously decreased,which suggests that microwave treatment can be a fast and thorough method to recover the polluted soil caused by too much fertilizer.更多还原
