根据2000～2008年相关数据进行逐步回归分析,发现武进区七(4)代褐飞虱发生量与8月份平均温度、9月中旬平均最低温度和四(1)代系统田虫量均呈显著正相关;与8月上旬平均最高温度呈显著负相关。据此建立了七(4)代褐飞虱发生量的回归预测方程。
Based on the stepwise regression analysis of the related data from 2000 to 2008, it was found that the occurrence of BPH in Wujin District was significantly and positively correlated with the average temperature in August, the average minimum temperature in mid-September and the population of four (1) generations of system insects. There was a significant negative correlation with the average maximum temperature in early August. Based on this, regression regression equation of seven (4) generations of BPH was established.
