摘要
为了明确休闲期豫北地区温室蔬菜土壤杀菌剂残留状况,分析豫北地区5个蔬菜温室春季黄瓜和秋季番茄休闲期土壤杀菌剂的种类和残留量。结果表明,多菌灵、甲基硫菌灵、甲霜灵、烯酰吗啉、嘧霉胺、咪鲜胺、三唑酮、苯醚甲环唑、百菌清等杀菌剂均能在土壤中检出,其中春季温室土壤中烯酰吗啉残留水平较高,最高为38.33μg/kg。秋季温室土壤中苯醚甲环唑残留水平较高,最高为62.70μg/kg。总体来看,豫北地区休闲期温室土壤仍存在杀菌剂残留。
To investigate characteristic of fungicide reside in greenhouse soil during fallow period,fungicide and residues in greenhouse were analyzed during fallow period of spring cucumber and autumn tomatoes.The results showed that fungicide including carbendazim,thiophanate-methyl,metalaxyl,dimethomorph,pyrimethanil,prochloraz,triazolone,difenoconazole and chlorothalonil were all detected.Dimethomorph residue was the highest with38.33μg/kg in fallow period in spring.However,difenoconazole residue was the highest with62.70μg/kg in fallow period in autumn.In a conclusion,fungicide residue was still in soil during fallow period.
