摘　　要：通过几年的定位试验,研究了不同生产模式日光温室黄瓜生产中主要病害的发生种类、流行特点及防治效果,结果表明:黄瓜病害主要以霜霉病、细菌性角斑病、白粉病、灰霉病为主,危害最重,土传病害及生理性病害有加重趋势。同一年份不同生产模式黄瓜主要病害常规模式发病最重,无公害模式次之,有机模式发病最轻。几种病害危害程度由重到轻的顺序为:霜霉病>白粉病>细菌性角斑病;灰霉病主要危害果实,在黄瓜结果盛期为害严重。有机模式对黄瓜主要病害控制效果最佳。In this paper we aim to examine effects of cucumber major diseases occurrence species, epidemic charac- teristics and controlling performance by study on three long-term greenhouses soil of organic, integrated and conventional farming systems. The results showed that the cucumber diseases were chiefly given first place to with downy mildew, bac- terial angular leaf spot, powdery mildew and gray mould. Soil passes disease and physiology venereal disease still had the tendency 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 angu- lar leaf spot. The gray mould chiefly harmed the fruit when flourishing phase the cucumber. Organic farming system was the optimum pattern of controlled effects to the major disease of cucumber.
