Abstract

The invention relates to a comprehensive remediation method of quinclorac herbicide contaminated soil in tobacco-rice rotation zones, belonging to the remediation technology of contaminated soil. The method is characterized by deeply ploughing the quinclorac herbicide contaminated soil after preceding crops are harvested, and digging big holes, turning down the upper layer soil and applying 1400-1600kg/ha of biomass carbon before succeeding crops are transplanted; spraying degrading bacterium SE08 liquid, wherein the concentration of the liquid is 1.5*1011cfu/L and the dosage is 40-60mL/hole; irrigating roots once with Shihaomei and Nengliang No.1 in the root elongation periods of the succeeding crops; and uniformly spraying Shihaomei and Nengliang No.1 onto the whole plants and the roots twice in the vigorous growing periods of the succeeding crops, wherein the concentrations and dosages of Shihaomei and Nengliang No.1 are recommended by manufacturers. Through combined utilization of chemical measures, 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.

Description

technical field [0001] The invention relates to a restoration technology for soil polluted by herbicides, in particular to a comprehensive restoration method for soil polluted by quinclorac herbicides in a tobacco-rice rotation area. Background technique [0002] The chemical name of quinclorac is 3,7-dichloro-8-quinoline carboxylic acid. It is a selective pre-emergence and post-emergence herbicide developed by BASF in Germany. It is mainly used to control barnyardgrass and other grasses in rice fields. Weeds have the advantages of wide application period, low dosage and good weeding effect. At present, this product has been registered on rice in my country. There are more than 150 products of quinclorac or its compound preparations in China. It has become the most widely used herbicide product in rice fields today. [0003] Due to the long residual effect period of the quinclorac herbicide, the time interval between the crops after planting is strictly required. If it is re...
