烟稻轮作区的二甲四氯除草剂致污染土壤综合修复法
摘要：
本发明涉及一种烟稻轮作区的二甲四氯除草剂致污染土壤综合修复法。属于污染土壤的修复技术。其方法是在前茬作物收获后对二甲四氯除草剂致污染土壤深耕，在后茬作物移栽前，挖大穴，将上层土壤翻下，施用生物质碳1500-1900kg/ha；并用降解菌SE08液喷施；其菌液浓度1.5×1011cfu/L，用量40-60mL/穴。本发明使用生物措施和物理措施联合使用缓解药害的效果好，使致污染土壤恢复正常的烟草植物学生长环境。
摘要（英）：

The invention relates to a comprehensive remediation method of 2-methyl-4-chlorophenoxyacetic acid herbicide contaminated soil in tobacco-rice rotation zones, belonging to the remediation technology of contaminated soil. The method is characterized by deeply ploughing the 2-methyl-4-chlorophenoxyacetic acid herbicide contaminated soil after preceding crops are harvested, and digging big holes, turning down the upper layer soil and applying 1500-1900kg/ha of biomass carbon before succeeding crops are transplanted; and spraying degrading bacterium SE08 liquid, wherein the concentration of the liquid is 1.5*1011cfu/L and the dosage is 40-60mL/hole. Through combined utilization of biological measures and physical measures, the effect of relieving phytotoxicity is good, so that the tobacco botanical growth environment of the contaminated soil returns to normal.
