Although azoxystrobin has been widely applied on various crops, little is known about the bioavailability of azoxystrobin in the soil-vegetable system. In this study, the uptake, accumulation and translocation of azoxystrobin as affected by soil characteristics and plant species were respectively investigated. The accumulation amount of azoxystrobin in pakchoi increased as soil adsorption decreased and was positively associated with its concentration in pore water (C_pw), which was mainly affected by soil organic matter content. Therefore, C_pw could be a candidate for the estimation of azoxystrobin accumulation in pakchoi. In all the tested vegetables, azoxystrobin was mainly accumulated in roots, and its upward translocation was limited. Root lipid content was a major factor affecting the uptake and translocation of azoxystrobin in different vegetables.

尽管嘧菌酯已广泛应用于各种作物，但对于嘧菌酯在土壤-蔬菜系统中的生物利用度知之甚少。本研究分别研究了受土壤特性和植物种类影响的嘧菌酯的吸收、积累和转运。唑菌胺在小白菜中的积累量随着土壤吸附量的减少而增加，并与其在孔隙水中的浓度（C _pw）呈正相关，主要受土壤有机质含量的影响。因此，C _pw可能是估计小白菜中嘧菌酯积累的候选者。在所有受试蔬菜中，嘧菌酯主要在根部积累，向上转运受到限制。根系脂质含量是影响不同蔬菜中嘧菌酯吸收和转运的主要因素。
