weather minimum
3.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.
