Influence of Different Precipitation Periods on Dendrolimus superans Occurrence:A biostatistical Analysis

Precipitation is one of the most important abiotic factors that affect Dendrolimus superans occurrence.In this study,a grey slope-correlation model was used,and a simplified grey slope-correlation model was constructed to uncover the most crucial periods of precipitation that pest occurrence.Results revealed that the two models are very similar;however,the simplified grey slope-correlation model required less calculative steps and was easier to operate.The c…查看全部>>
