通过对灰飞虱越冬越夏场所与寄主植物调查及其在麦田、水稻上的空间分布型与抽样技术研究,在试验的基础上,提出综合防治技术措施,形成了一套适合本地推广应用的综合防治技术。它的推广应用使灰飞虱种群数量明显下降,条纹叶枯病控制在较低水平,示范区水稻产量比非示范区增加251.10kg/hm2,节省防治工本26.63%。
Based on the investigation of the habitat and host plants of overwintering Laodelphax striatellus and their spatial distribution patterns and sampling techniques in wheat field and paddy field and on the basis of experiments, this paper put forward the comprehensive measures for prevention and control, and formed a set of methods suitable for local popularization and application Integrated control technology. Its popularization and application led to a significant decrease in the population of Laodelphax striatellus and stripe blight control at a relatively low level. The rice yield in the demonstration area was increased by 251.10 kg / hm2 over the non-demonstration area, saving 26.63% of the prevention and treatment cost.
