摘要
利用青海省贵南县热量、降水、日照等气象资料,对贵南地区小油菜发育期的动态预报模型进行验证。利用实际天数减去模拟天数,最大误差为5.7 d,最小误差为0.1 d。利用预报所得气象要素结合各发育期回归方程去靠拢最适宜发育期天数指标,即为预报天数。
By using heat, precipitation,sunshine data in Guinan County,dynamic forecasting model for spring rape development period was verified.The results showed that compared the simulated days with the true days, the errors were within 0.1 days to 5.7 days.
