玉米穗、茎腐病病原学的相互关系研究表明:其优势致病菌禾谷镰孢菌和串珠镰抱菌均可交互侵染引起这两种病害,并且能从植株的外侧和内部由基部向穗部传染,初步证实引起穗腐病的镰孢菌是来自茎腐病的镰孢菌。穗、茎腐病的发病条件试验结果显示,玉米茎腐病与玉米品种的抗性、生育期、种植密度、地势、降水和施肥等的关系极为密切,而玉米穗腐病与玉米品种的抗性、土壤类型、种植形式和螟害的关系密切。通过施用钾肥和防治玉米螟可有效地减轻玉米茎腐病和穗腐病的危害。
The correlation between ear rot and stalk rot etiology showed that the predominant pathogens Fusarium graminearum and Fusarium moniliforme were both infectively infecting these two kinds of diseases and could be induced from the outside and the inside of the plant by the base To spike infected, initially confirmed that the ear rot caused by Fusarium stalk rot from the Fusarium. The results showed that the relationship between corn stalk rot and maize variety resistance, growth period, planting density, topography, precipitation and fertilization were very close. However, the relationship between corn ear rot and maize variety Sex, soil type, planting forms and stem borer are closely related. Through the application of potassium and corn borer can effectively reduce the corn stalk rot and ear rot disease hazards.
