| 摘 要： | 根据田间调查和病原菌鉴定,明确了河西走廊玉米穗粒病是由8种病原菌复合侵染所致。其中Fusariummoniliforme和F.graminearum共同组成了玉米穗粒腐病的优势菌种。探明了玉米穗粒腐病的发生与品种抗性、环境条件、种植密度、施肥量及虫害之间的关系。

| Abstract: | In this paper,it was suggested that the compound infection of eight fungus caused corn spike kernel rotten by investigation and germs identification.Among the eight fungus,Fusarium moniliforme and F.graminearum were much more than the others.The result also showed that the occurrence of this disease related with variety resistance,environmental condition,plant density,quantity of fertilizer and insect pest. |
