摘要： 文章通过研究不同栽培方式下灰飞虱发生数量及其与水稻条纹叶枯病的发生关系、不同水稻品种间条纹叶枯病田间自然消长规律。结果表明：不同水稻品种间条纹叶枯病发病程度差异明显；而灰飞虱发生数量与条纹叶枯病的发生程度呈正相关；而推迟播期、推广轻简栽培方式有利减轻前期水稻条纹叶枯病的病情。

Abstract: Generation amount of rice hopper in different cultivation and its relations with rice striper,natural living pattern in field on different varieties had been observed.The results showed:Difference of rice striper on different varieties was significant,positive correlation was between amount of hopper and rice striper generation.Late sowing and simple cutivation would be helpfull for reducing rice striper in early period.
