| 摘 要： | 南方水稻黑条矮缩病为白背飞虱传播的一种毁灭性的水稻病毒病。文章根据2009~2016年化州地区南方水稻黑条矮缩病发生和危害情况,通过对南方水稻黑条矮缩病病害症状和介体昆虫的认识,分析南方水稻黑条矮缩病发生的轻重与介体数量、毒源量、水稻品种、种植方式、水稻播期、秧田位置及气候条件等因素有关。提出全面实施“防控技术前移,切断毒源,治虫防病”的防治策略；形成适合粤西稻区特点的南方水稻黑条矮缩病综合防控的技术体系,并在生产上推广应用,有效预防控制了南方水稻黑条矮缩病发生流行危害,取得了显著的社会经济效益。

| Abstract: | Southern rice black-streaked dwarf virus (SRBSDV) is a kind of ruinous rice virus disease transmitted by the whitebacked planthopper. Basing on the occurrence and harm of SRBSDV in Huazhou district from 2009 to 2016, with recognization of the disease symptom and insect vector of SRBSDV, the essay analyzes that the severity of SRBSDV is related to vector numbers, viral source capacity, rice species, planting patterns, rice sowing period, seedling bed position and climate condition. The control strategy, which includes putting forward prevention and control technology, cutting off viral source, defending against insects, is proposed for comprehensive application. The synthetical preventing SRBSDV technical system which adapts to rice region in the western part of Guangdong province is implemented. The technical system is promoted and applied in production. With the measures above, the epidemic risks of SRBSDV can be prevented and controlled to obtain remarkable social and economic benefits. |
