摘要
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 rice stripe virus (RSV)swelling up in recent years in Jiangsu province are mostly related with extending of susceptible rice varieties and the enlarging population of small brown planthopper, Laodelphax striatellus(SBPH). Based on the analysis and the control practice in field, the integrated control methods were recomended, such as control for SBPH to prevent RSV source, extending effective agriculture methods such as planting resistant rice varieties, growing rice seedling in dry condition in fertile bed and scattering transplanted small seedling and putting sowing time off to avoid the peak of migration of SBPH.
