摘要
对6年调查材料研究表明,在杭州的气候条件下,茶橙瘿螨的种群数量消长存在“单峰型”和“双峰型”两种类型。在发生“双峰型”的年份,种群密度第1个高峰比第2个高峰大。统计分析结果表明,该螨发生首次最高高峰日,与1月份总降水量和相对湿度之间呈正相关,据此采用列联表预测方法,对历史材料进行验证,其符合率为100%。该预测法具有方法简易,应用方便,预测期长等优点。
Based on the survey in six years period, the fluctuation of Tea Pink mite population showed two types in Hangzhou area,i.e.,mono-peak and dual-peak. In the dual-peak year , the population density of mite in the first peak is higher than that in the second peak. The results of statistics and analysis showed that the firstmaximum peak date of mite was positively correlated with the total rainfall and relative humidity in January.Based on this correlation,the historical information was verified by using the contingency table predictionmethod,and the conforming percentage was 100%. This prediction method possesses the advantages of sim-ple ness,convenience and longer prediction date.
