摘　　要： 南方水稻黑条矮缩病是由南方水稻黑条矮缩病毒引起的水稻病毒病,现已成为中国水稻生产中重要的病毒病害。通过对该病害2009年以来的发病情况研究分析,初步明确其每年的发病程度不但与毒源地病虫发生情况、水稻生育期、水稻品种抗病性及气象条件等密切相关,还与本地水稻播种时间、栽培方式、地形、地貌等密切相关。一般情况下,只有当带毒白背飞虱迁入期与水稻秧苗期或本田早期相吻合,而且迁入数量及其繁殖速率足够大时,才会引致病害严重发生。通过总结病害流行的影响因素,拟定了病害调查监测和长、中、短期配套的测报技术方法,为实施病害科学监测和防治奠定了基础。 Southern rice black-streaked dwarf disease （SRBSDD）, caused by Southern rice black-streaked dwarf virus （SRBSDV）, had been developed as one of the most important rice virus diseases in China since its first discovery in 2001. Based on analysis of SRBSDD occurring since 2009, it was clear that the disease closely related to occurrence of WBPH, rice growth period, resistance of varieties, weather condition in virus source region, and was relevant to rice sowing time, cultivation pattern and landform in local area also. In generally, necessary condition of SRBSDD occurring was that immigration of WBPH carrying SRBSDV meet the period of rice seeding or tillering stages, and with mass immigration and enough reproduction. Influence factors of disease epidemics were summarized and protocols of monitoring and long-term, middle-term, short-term forecasting were proposed, which was foundation for its scientific monitoring and control.
