土壤处理剂对土壤钾和重金属含量的影响

摘要

[目的]寻找能够改良土壤的土壤处理剂,探索不同土壤处理剂对土壤的改良效果.[方法]通过5种不同处理剂在豇豆的田间试验,研究不同土壤处理剂对豇豆产量和土壤中钾、砷、铅、汞和镉等含量的影响.[结果]施用土壤处理剂后豇豆产量均高于对照;土壤中重金属含量均有不同程度的下降.[结论]施用土壤处理剂有利于降解土壤中重金属.%[Objective] To find soil treatment agents that can improve soil,and explore the improvement effect of soil treatment agents on soil. [Method]Through five different treatment agents in cowpea field experiment, the effect of different soil treatment agents on potassium, arse-nic,lead,mercury and cadmium and other heavy metal content in soil and cowpea yield was studied.[Result]After applying soil treatment a-gents,the yield of cowpea was higher than that of control,the content of heavy metals in soil decreased at different degrees.[Conclusion]The application of soil treating agent is beneficial to the degradation of heavy metals in soil.
