Abstract:

According to the observation data of flowering period of oil peony in Heze City from 2008 to 2019 and the corresponding meteorological elements, the main meteorological factors affecting the flowering period of oil peony in Heze City were analyzed by using the mathematical statistical methods of moving average, correlation analysis and stepwise regression. The results showed that temperature was one of the main meteorological factors affecting the first flowering period of oil peony, and had a significant negative correlation with the flowering period; sunshine, precipitation and daily range had no significant correlation with the first flowering period of oil peony. Based on the meteorological factors that had great influence on the flowering period of peony from 2008 to 2018, a forecasting model for the first flowering period of oil peony was established by using the stepwise regression method, which could release the flowering forecast on March 21 and April 1 respectively. The accuracy of the model was 100% in 2019 and 2020, and the fitting degree was ideal. The model has a good forecasting effect and could meet the needs of meteorological services.

Key words: oil peony, initial flowering period, flowering forecast, meteorological factors, forecast model
