分析了江苏省近年来水稻条纹叶枯病的上升原因,主要与感病品种面积扩大,灰飞虱发生量逐年加大等因素有关。在此基础上,结合本省各地防治实践,初步提出了控制条纹叶枯病综合防治措施,即坚持以“治虫防病”为主,结合推广有效农业措施,如种植抗性品种,以及肥床旱育、小苗抛栽等有利于推迟播期,避开灰飞虱迁移传毒高峰的轻型栽培技术。
The reasons for the rise of rice stripe blight in Jiangsu Province in recent years were analyzed, mainly related to the expansion of susceptible varieties and the year-on-year increase of SBPH. On this basis, combined with the prevention and control practices in different parts of our province, we put forward the integrated prevention and control measures for controlling stripe blight, that is, sticking to the principle of “pest control and disease prevention” and combining with effective agricultural measures such as planting resistant varieties, Yu, throwing planted seedlings and other conducive to postponed sowing date, to avoid the transfer of Laodelphax striate transmission of light cultivation techniques.
