| 1. | The models were validated with adopting local weather ( average temperature per month , average maximum temperature per month ; average minimum temperature per month ; sunlight times per month , and latitude ) , varieties , and experiment data from different yielding levels in nanjing and jinan areas , the correlation coefficient , standard error of absolute deviation , and average absolute deviation between the observed and the stimulated were 0 . 9761 and 0 . 9620 with 0 . 01 significant level , 0 . 5891 and 0 . 7094 , and 0 . 12 and 0 . 43 , respectively
所建模型可以利用当地常年气象资料（ 30年平均值，如月平均气温、月平均最高和最低气温以及月日照时数、纬度） ，确定不同地区、产量水平与品种最适叶面积指数动态，为小麦数字化栽培提供科学依据。 |
