粤西地区南方水稻黑条矮缩病的流行规律及防治
Southern Rice Black-streaked Dwarf Disease:The Epidemic Law and Control in Western Guangdong
摘要
Abstract
Southern rice black-streaked dwarf disease is a kind of destructive rice virus disease transmitted by the 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 and insect vector, the authors found that:the severity of rice black-streaked dwarf disease was related with vector quantity, viral source capacity, rice species, planting patterns, rice sowing period, seedling bed position and climate condition. And a comprehensive control strategy was proposed, which included developing the technology for the earlier prevention and control, cutting off viral source, and defending against insects. The synthetic technical system against rice black-streaked dwarf disease, which adapted to rice growing region in western Guangdong, was built up and applied widely. As a result, the epidemic risk of rice black-streaked dwarf disease is prevented effectively, and remarkable social and economic benefits are obtained.关键词
