ENSO事件和太阳黑子活动与我国长江中下游稻区褐飞虱大发生关系的研究
A Study on Relationship between ENSO Event,Activity of Sunspot and Outbreak of Nilaparvata lugens in Middle and Lower Reaches of Yangtze River
摘要
Abstract
According to the data of oceanic Ni(n)o index during 1954 to 2010, the relative number of sunspot during 1937 to 2009, and the outbreak of rice brown planthopper (Nilaparvata lugens) in the middle and lower reaches of the Yangtze River from 1957 to 2009, the relationship between ENSO event, the activity of sunspot and the outbreak of N.lugens in the middle and lower reaches of the Yangtze River was studied by using phase analysis, correlation analysis and key-time analysis.The results indicated that the outbreaks of N.lugens were mainly found in the last year of sunspot valley years and the same year of El Ni(n)o years, the possibility of no-outbreak in sunspot valley years and in the fourth year after La Ni(n)a years was greater.In addition,the outbreak years of N.lugens mainly appeared at the declining stage of sunspot cycle.There was significantly positive correlation between the relative number of sunspot 17 years ago and the outbreak of N.lugens in the same year.Sunspot activity had obvious periodicity of about 11 years, and the outbreak of N.lugens had the periodicity of 8 -9 years in some areas.关键词
