摘要
从10种预测模型中筛选出最佳模型210bbWLbA=,并分析了不同取样量对其预测精度的影响,取样量为20片叶时误差小,精度高,且对早酥梨、苹果梨预测精度分别在94.52 %、90.20 %以上。预测40片叶时精度较预测单叶高。
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 %.
