摘要
以河北平山片麻岩及花岗岩山地贫瘠土壤为研究对象,探究施用不同肥料对土壤重金属质量分数的影响。从土壤中Cr离子质量分数在各化肥不同施肥处理中的结果来看,SF2处理(27.74×10-6)较CK减少的幅度最大,为49%,化肥NK2处理较CK减少了47%,生物有机肥BF2处理(30.69×10-6)较CK减少了45%,微生物菌剂MA2处理(28.56×10-6)较CK减少了11%。实验结果显示:缓释复混肥SF2处理能保证土壤质量安全,促进土壤可持续发展,不会对土壤环境质量产生负面影响,是较理想施肥措施。
An experiment was conducted to study the effect of different fertilizers on soil heavy metal content in infertile soil in granite-gneiss area of Pingshan County,Hebei Province.Different fertilizers included urea（total N content more than 45.3%）,fused calcium magnesium phosphate（P2O5 content more than 12%）,potassium chloride（K2O content more than 56%）,slow release compound fertilizer（mass ratio of N,P,K is 12∶17∶13）,compound microorganism preparations and bio-organic fertilizer.Results showed that the soil chromium-ion content for the treatment of slow release compound fertilizer applied 100g per hole decreased by 49% compared with the control（without fertilizer application）,then that of chemical fertilizer（100g urea and 100 g potassium chloride per Armeniaca sibirica seedling）,bio-organic fertilizer applied 1000g per hole and compound microorganism preparations applied 100g per hole decreased by 47%,45% and 11% respectively.Results show that the treatment of slow release compound fertilizer applied 100g per hole is a more satisfactory fertilization practice,which helps to ensure soil safety and promote the sustainable development of the soil without adverse effect on the quality of soil environment.
