    Correlation Analysis on Dynamics of Planthopper Population and Meteorological Factors in Different Resistant Rice Varieties

      摘要
    • 摘要: 田闻系统调查结果表明,不同抗性水稻品种间稻飞虱种群在时间系列上呈现迁飞规律一致;向北迁出前期,褐飞虱Nilaparvata lugens种群在水稻2个敏感生育期间有所选择,6月底种群高峰集中在孕穗期水稻上,在7月上中旬转移至分蘖期水稻,回迁种群高峰出现在分蘖中期水稻上;白背飞虱Sogatella furcifera种群小范围生境转移规律性不强.灰色关联分析结果显示,日均温和日均气压对褐飞虱种群数量波动的影响最大,当天的关联度分别为0.387 3和0.384 6,而回推3 d的关联度分别上升至0.449 0和0.424 3;降雨量和相对湿度属于短期效应因子,日照时数属中长期效应因子,而日均风速的作用介于二者之间.

       

      Abstract: The results from systematical investigation in field indicated that the migration regularity of the population of rice planthoppers Nilaparvata lugens and Sogatella furcifera kept temporal consistency in different resistant rice varieties.The N.lugens populations were different between two sensitive rice growth stages before northward migration,and aggregated in boot stage at the end of June and migrated to mid-tillering stage in early and middle July,however the maximal population of southward migration on...
