| 摘 要： | 对冀南地区推广的36个玉米品种进行了田间自然发生条件下的病虫害调查。结果表明：不同玉米品种的病虫害发生程度存在差异,大多数玉米品种对玉米蚜虫缺乏抗性,对传统病害如玉米大斑病、玉米小斑病、玉米弯孢叶斑病等发病较轻,但近几年新出现的病害如玉米褐斑病、玉米锈病等发病普遍或较重。另外还分析了影响玉米锈病和玉米蚜虫发生的因素,认为发生程度除受品种抗性等因素影响外,主要取决于8月下旬～9月中下旬的温度、湿度和降雨量。

| Abstract: | The diseases and pests of 36 corn commercial varieties under natural condition in South Hebei were investigated.The results showed that there were differences among the occurrence degree of diseases and pests of different corn varieties.Most varieties were not resistant to aphid,and they were lightly susceptible to northern leaf blight of corn,southern leaf blight of corn and curvularia leaf spot disease,while the corn brown spot and corn rust were common and serious in recent years.Except for the variety resistance,the temperature,humidity and precipitation were the main factors influencing the occurrence of aphid and corn rust from the last ten days of August to the middle and last September. |
