| 摘 要： | 运用茆智提出的ET0预测方法,并结合其他学者对方法的改进,利用日常的天气预报信息,分别对豫北地区的冬小麦和夏玉米生育期内的ET0进行了预测。结果表明,在冬小麦生育期的ET0预测值,返青前绝对误差不超过0.8mm/d,返青以后93%的预测结果相对误差小于20%,53%的预测结果小于10%;在夏玉米生育时期内的预测值,95...

| Abstract: | Based on daily weather forecast information,reference crop evapotranspiration(ET0) in winter wheat and summer maize growth period was forecasted respectively by Maozhi forecasting model and improved measure of this model in north Henan province in this article.The results showed that absolute error of predictive value was less than 0.8 mm/d before green stage,relative error of 93% was less than 20%,and relative error of 53% was less than 10% after green stage in winter wheat period;Relative error of 95% was... |
