| 摘 要： | 2009年对甘肃省9个市的21个县、区玉米穗腐病、茎基腐病的发生危害情况进行了全面调查，并采集病害标样，进行病原分离。调查结果表明，玉米穗腐病、茎基腐病在全省各玉米种植区均普遍严重发生，病田率100%，病穗率和病株率平均为63.57%和34.47%。初步分离结果表明，全省玉米穗腐病、茎基腐病的主要致病菌为禾谷镰刀菌、黄色镰刀菌和轮枝镰孢菌，但在地区间的分布有明显差异。

| Abstract: | The occurrence and damage of maize kernel rot and corn stalk rot were comprehensively investigated in 21 counties of 9 cities in Gansu in 2009.The representative samples of the diseases were collected and the pathogens were isolated on PSA.The results showed that the disease of maize kernel rot and corn stalk rot seriously occurred in main maize-producing areas of the whole province.The rate of diseased fields reached to 100%,and the rate of diseased spikes and infected plants were 63.57% and 34.47%,respect... |
