合理安排间、轮、套作可有效缓解蔬菜连作障碍现象,促进瓜类蔬菜的生长,降低病害的发生,而通过栽培方式减轻植物气传病害的研究相对较少。黄瓜生产中存在的主要气传病害是黄瓜霜霉病,是由鞭毛菌亚门、假霜霉属真菌侵害黄瓜植株所引起的,并能够在一定的温度和湿度条件下迅速传播。基于此,在已有研究的基础上,对小麦伴生降低霜霉病发生原因进行进一步探究。通过对霜霉病发生情况及影响其发生的环境温度和湿度进行测定,发现小麦伴生能够在一定程度上降低设施内环境的湿度,进而抑制黄瓜霜霉病的发病率和病情指数。
Reasonable arrangement of intercropping, rotation and intercropping can effectively alleviate the continuous cropping obstacles in vegetables, promote the growth of melons and vegetables, and reduce the occurrence of diseases. However, there are relatively few researches on alleviating the airborne diseases of plants through cultivation. The main airborne disease in cucumber production is cucumber downy mildew, which is caused by the flagellum subfamily, the pseudomycotina fungus infects the cucumber plants and can rapidly spread under certain temperature and humidity conditions. Based on this, based on the existing research, the cause of downy mildew reduction associated with wheat was further explored. By measuring the occurrence of downy mildew and the environmental temperature and humidity that affect the occurrence of downy mildew, it was found that accompanied by wheat can reduce the humidity in the environment of the facility to a certain extent, thereby inhibiting the incidence and disease index of cucumber downy mildew.
