蔬菜不同轮作方式对甜瓜病害的影响

Effects of Different Vegetable Crop Rotation Patterns on Plant Disease of Muskmelon in Greenhouse

供试品种采用"春甜三号"甜瓜、东农709番茄、八月绿菜豆、实心芹芹菜、长白大葱,在温室中利用垄作栽培方式,研究番茄、菜豆、芹菜、大葱与甜瓜的不同轮作,对甜瓜主要病害的影响。结果表明,大葱和菜豆与甜瓜轮作显著降低了甜瓜霜霉病的发病率(P<0.05);大葱和菜豆以及菜豆和芹菜与甜瓜轮作显著降低了甜瓜细菌性叶斑病的发病率(P<0.05);菜豆和芹菜与甜瓜轮作显著降低了甜瓜白粉病的发病率(P<0.05)。综上所述,菜豆和芹菜与甜瓜轮作对甜瓜主要病害有显著的抑制作用。

The melon cultivar ＆quot;Chuntian 3＆quot;,the tomato cultivar ＆quot;Dongnong 709＆quot;,the bean cultivar ＆quot;August Green＆quot;,the celery cultivar ＆quot;Solid Celery＆quot; and the onion cultivar ＆quot; Changbai ＆quot; were used as materials tak-ing ridge planting in the greenhouse （celery using flat beds and sowing method）.Tomatoes,beans,celery and onion are used to crop rotation cultivation in the greenhouse,in order that we compared the effect of the main of plant disease.Results show that the incidence of melons downy mildew is significantly reduced than other treatments on the crop rotation of onion and beans （P〈0.05）;the incidence of the melon bacte-rial leaf spot is significantly reduced than other treatments on the crop rotation of onion and beans and the crop rotation of beans and celery （P〈0.05）;the incidence of the melon powdery mildew is significant-ly reduced than other treatments on the crop rotation of beans and celery （P〈0.05）.To sum up the crop ro-tation of beans and celery has significant inhibitory effect on the main diseases of melon.
