参考作物需水量实时预报方法研究进展

Research Progress of the Method for the Real-time Forecast of the Reference Crop Evapotranspiration

参考作物蒸发蒸腾量预测是实时灌溉预报的重要环节,对于节约用水、增加作物产量和农业经济效益起着重要作用。评述了参考作物蒸发蒸腾量实时预报的几种方法,指出了在具体应用时宜结合实际情况进行模型的优化择选以提高预测精度。

The forecast of the reference crop evapotranspiration is a necessary step of the real-time forecast of irrigation, and it plays an important role in saving water, increasing crop yields and economic benefits in irrigation area. Several methods and models for the real-time forecast of the reference crop evapotranspiration were discussed. The opinion of optimization between different models was proposed during application.
