| 摘 要： | 对衡阳水稻病虫害特点及其与气象相关性进行研究,结果表明,衡阳虫害发生面积是病害的近4倍,而病害的危害严重程度是虫害的2倍以上;虫害与病害所造成的减产损失分别为57.83%和42.17%;夏季强降水有利于病虫害的发生;随着气候变暖,低温天气对当地虫害越冬的抑制作用在减弱,而对迁徙性害虫的影响微乎其微;高温高湿天气有利于纹枯病的发生和蔓延,中、晚稻破口至抽穗期如遇高温干旱天气,则不利于稻曲病的发生。 |

| Abstract: | The characteristics of pest disease of Hengyang rice and its correlation with the meteorology are analyzed,the results show that the area suffered from pest are nearly four times more than that suffered from disease,while the damage degree of disease is twice more than that of pest.The pests and the diseases have caused about 57.83% and 42.17% lost in grain.The heavy rainfall in summer usually breeds pest disease.As the climate grows warmer,the inhibition effect of cold weather on local pest disease is weak... |
