在气候考察和田间试验的基础上，利用农田水分平衡方程和联合国粮农组织（ Ｆ Ａ Ｏ）最新公布的计算作物蒸散量的方程，结合春小麦发育期及其需水规律、新灌区气象、土壤参数，并参考我国目前几种节水灌溉模式，订制了宁夏扬黄新灌区春小麦灌溉量及灌溉时次，为新灌区灌溉制度的制定和节水农业的实施提供农业气象依据。 On the basis of climate investigation and field experiment, using the equation of cropland water balance and the latest formula of calculating the crop evapotranspiration published by the Food and Agriculture Organization of the United Nations (FOA), combining with the developmental period of spring wheat and its water requirement, the meteorological and soil parameters , And with reference to several current water-saving irrigation modes in China, we customized the irrigation amount and irrigation times of spring wheat in Yanghuang New Irrigation Area in Ningxia to provide agricultural meteorological evidence for the formulation of irrigation system and implementation of water-saving agriculture in new irrigation area.
