以华北地区冬小麦为研究对象,将AquaCrop作物生长模型应用到滴灌、喷灌、漫灌中,对模型主要参数如气象、土壤、作物特性等进行调整,并对作物产量和生物量模拟的有效方法进行了研究。模拟结果表明,产量和收获时地上部分生物量的模拟值与实测值较为接近且略高于实测值,模型性能指数均高于0.95。产量模拟效果优于生物量,滴灌模拟效果最好。
Taking the winter wheat in North China as the research object, AquaCrop crop growth model was applied to drip irrigation, sprinkler irrigation and flood irrigation. The main parameters of the model such as meteorology, soil and crop characteristics were adjusted, and the effective methods of crop yield and biomass simulation the study. The simulation results showed that the simulated and aboveground biomass yield and harvest biomass were close to and slightly higher than the measured values, and the model performance indexes were both higher than 0.95. Yield simulation effect is better than biomass, drip irrigation simulation best.
