摘　　要：Objective] The effects of four QoI fungicides on potato and tomato and cumumber quality and yield formation under disease-free conditions were studied in order to research the physiological effects of four QoI fungicides on these fruit veg-etables and explore the range of minium dose for the obvious physiological effect and the dose for the maximum effect. [Method] The effects of four strobilurin fungi-cides on yield formation and quality were studied under disease-free conditions in the field. Two applications of each strobilurin fungicide were designed. The yield and commercial ratio for each application were investigated. [Results] The minimum dose for the obvious physical effect on potato and tomato and cucumber was lower than 133 mg/L , the dose for maximum effect on patoto and cucumber of the four stro-bilurin fungicides maybe also lower than 667 mg/L. The dose of fenaminstrobin and pyraoxystrobin for maximum effect on tomato maybe also lower than 667 mg/L. [Conclusion] The study suggested that enotroburin, fenaminstrobin, pyrametostrobin and pyraoxystrobin were able to increase the yield and ratio of high quality potato and cucumber and tomato.[目的]研究4种甲氧基丙烯酸酯类杀菌剂对马铃薯、番茄、黄瓜保健增产效应,探索4种杀菌剂无病害压力下保健增产的有效起始剂量或饱和剂量存在范围及保健增产的幅度。[方法]供试药剂共4种,每种药剂设2个浓度。通过田间试验,调查了每个处理马铃薯、番茄及黄瓜的产量或优质率。[结果]烯肟菌胺、烯肟菌酯、唑菌酯与唑胺菌酯对马铃薯、番茄、黄瓜保健增产有效起始剂量应低于133 mg/L;对马铃薯、黄瓜保健增产的饱和剂量应低于666.7 mg/L。烯肟菌胺与唑菌酯使番茄保健增产的饱和剂量应低于667 mg/L。[结论]烯肟菌胺、烯肟菌酯、唑菌酯及唑胺菌酯3种杀菌剂对马铃薯、番茄及黄瓜均具有明显的保健增产效应,值得推广。
