用计算机对13年苹果园山楂叶螨种群变动与温湿度资料的统计分析表明:①山楂叶螨卵期和幼若螨期与日均温度呈高度负相关;②山楂叶螨种群发生高峰的界限指标是日平均温度为27.34±1.91℃,日平均相对湿度65.54±11.20％;③山楂叶螨在发育起点温度9.2℃至发生高峰的温湿度界限指标范围内,其种群增长与有效积温呈高度正相关,与累计温湿系数亦呈高度正相关;④苹果园内温湿度与气象站温湿度的关系呈高度正相关。此研究结果为山楂叶螨种群的预测奠定了理论基础。
Computer analysis of 13-year apple orchard hawthorn spider mite population changes and temperature and humidity data show that: (1) hawthorn spider mite egg stage and juvenile mite period and daily average temperature was highly negative correlation; ② hawthorn spider mite population peak occurrence limit The index is that the average daily temperature is 27.34 ± 1.91 ℃ and the average relative humidity is 65.54 ± 11.20%. ③The hawthorn spider mite has a positive positive correlation with the effective accumulated temperature within the range of the threshold temperature and humidity at the start of development Correlation, and the cumulative coefficient of temperature and humidity also showed a highly positive correlation; ④ apple orchard temperature and humidity and weather station temperature and humidity was highly correlated. The results of this study laid the theoretical foundation for the prediction of hawthorn spider mite population.
