六六六等有机氯杀虫剂在我国已停止生产,这对控制污染,改善我国环境状况,必将产生深远的影响。六六六停止使用后,农药对作物的直接污染基本上结束。但由于六六六在土壤中的高残留和稳定性,在停用后相当长的一段时期内,土壤中的六六六残留物便成为污染农作物的主角。在六六六农药严重污染的农田中如何选择栽培作物,防止土壤中六六六残留物危害是当前农业生产中 Hexachlorocyclohexane and other organochlorine pesticides have ceased to be produced in our country, which will certainly have a profound impact on controlling pollution and improving the environmental conditions in our country.

However, due to the high residue and stability of 666 in the soil, the HCH residues in the soil have become the protagonists of contaminated crops for a relatively long period of time after its deactivation. How to Choose Cultivated Crops in Farmland Severely Contaminated with 666 Pesticides to Prevent the Harm of HCH Residues in the Soil from Current Agricultural Production
