| 摘 要： | 2010—2011年对湖南省水稻大面积生产中南方水稻黑条矮缩病发生情况进行了调查,发现该病的发生在不同年份、地区及品种间存在明显差异,发病面积和程度均为湘南>湘中>湘北。发病时间以湘南早于湘中、湘北,2010年发病重于2011年。分析其发病差异的主要原因,可能与4—9月由西南暖湿气流引起带毒白背飞虱迁入湖南省的时间迟早、机会多少及是否采取有效防治措施和品种抗病性等有关。 |

| Abstract: | The investigations on the incidence of southern rice black-streaked dwarf virus(SRBSDV) in commercial rice production in several regions of Hunan Province were conducted in 2010 and 2011.The results showed that there were significant differences of the incidence for this disease in different years,regions and rice varieties.The incidence of SRBSDV was more serious in 2010 than in 2011.The initial date of the virus incidence was earlier in south Hunan than in central and north Hunan.The tendency in both the area and degree of the disease incidence was south Hunan > central Hunan > north Hunan.Moreover,the reasons of the difference for this virus incidence were analyzed and the major factors related to the incidence of SRBSDV were thought to be as follows:(1) The time and opportunity of migration into Hunan Province for white-backed planthopper,Sogatella furcifera(Horváth),which transmits this virus via warm and wet southwest-wind from April to September;(2) whether to take effective measures for prevention;(3) rice variety resistance to this virus. |
