采用数据统计方法对22a麦蚜及其影响因子观察资料进行分析,结果表明,2月下旬平均气温、3月下旬至4月上旬平均相对湿度和4月中旬蚜量是影响小麦穗蚜发生程度的关键因子,并由此组建了中、长期预测模型。
The statistical data were used to analyze the data of the observed observation on the 22a wheat aphid and its influencing factors. The results showed that the average temperature in late February, the average relative humidity in late March to early April, and the amount of aphids in mid April were the most influential factors Key factors, and set up a medium and long-term forecasting model.
