Abstract: In this paper we aim to examine effects of cucumber major diseases occurrence species,epidemic characteristicsand controlling performance by study on three long -term greenhouses soil of organic,integrated and conventionalfarming systems.The results showed that the cucumber diseases were chiefly given first place to with downy mildew,bacterialangular leaf spot,powdery mildew and gray mould.Soil passes disease and physiology venereal disease still had thetendency to aggravate year by year at present.The prevalence situation was conventional patterns > integrated patterns >organic patterns in the same year.Several diseases harm degree was downy mildew > powdery mildew > bacterial angularleaf spot.The gray mould chiefly harmed the fruit when flourishing phase the cucumber.Organic farming system wasthe optimum pattern of controlled effects to the major disease of cucumber.
