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。笔者根据2007—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。
Southern rice black-streaked dwarf disease is a kind of destructive rice virus disease transmitted bythe white-backed planthopper. According to the occurrence pattern and the harm of southern rice black-streaked dwarf disease in Huazhou from 2007 to 2016, and with the recognition of the disease symptom andinsect vector, the authors found that： the severity of rice black-streaked dwarf disease was related with vectorquantity, viral source capacity, rice species, planting patterns, rice sowing period, seedling bed position andclimate condition. And a comprehensive control strategy was proposed, which included developing thetechnology for the earlier prevention and control, cutting off viral source, and defending against insects. Thesynthetic technical system against rice black-streaked dwarf disease, which adapted to rice growing region inwestern Guangdong, was built up and applied widely. As a result, the epidemic risk of rice black-streakeddwarf disease is prevented effectively, and remarkable social and economic benefits are obtained.
