摘　　要：玉米是重要的粮食、饲料和能源作物,是世界三大农作物之一。玉米细菌性茎腐病是玉米的常见病害,给我国玉米产业造成了较大的损失。为了更好地研究玉米细菌性茎腐病,本文梳理了该病害的症状与为害、病原学特性、流行规律、防治方法和致病机制等信息。玉米细菌性茎腐病菌寄主范围广,在土壤和病残体中存活时间长,且高温条件下果胶酶活性高。因此,今后需要加强对玉米细菌性茎腐病的研究和防治,以避免该病害更大范围的流行。As an important food,feed,and energy crop,maize(Zea mays L.)is one of the three major crops in the world.Bacterial stalk rot is a prevalent disease of maize that has caused great losses to the maize industry in China.The damage and symptoms,etiologic characteristics,epidemic patterns,control methods,and pathogenic mechanism of the disease were reviewed in this article for its better study.The pathogen of bacterial stalk rot of maize had a wide range of hosts and it could survive in soil and infected tissues for a long time.What’s more,the pectinase activity of the pathogen was high in high-temperature conditions.So,it is necessary to strengthen the research and prevention of bacterial stalk rot of maize in the future to curb its prevalence.
