| Abstract: | The best one (210bbWLbA=) was selected from 10 forecasting models, and the effects of different sampling numbers on forecasting precision were analysed. While the sampling numbers are 20 leaves, deviation is the least and precision is the highest. If Zaosu pear and Pingguo pear are forecasted by the forecasting model,their precision is above 94.52 % and 90.20 %. |
