摘  要:
根据郑州市华北水利水电大学农业节水灌溉试验场2013-2014年夏玉米实测数据,利用土壤水环境分析软件IrriMax的根区分析功能,对夏玉米的计划湿润层深进行修正;通过作物系数修正模型对夏玉米的作物系数进行修正,并利用土壤水分预测模型对2014年夏玉米生育期内土壤水分进行模拟,最后进行模拟结果分析。结果表明河南地区夏玉米全生育期的作物系数为0.80,2014年夏玉米整个生育期内土壤水分预测值与实测值基本吻合。

摘  要:
According to the field experiments from 2013 to 2014in water-saving irrigation proving ground in North China University of Water Resources and Electric Power,the irrigation wetting depth was corrected by using root zone analysis function of the IrriMax,the crop coefficient was achieved by crop coefficient correction model and the soil moisture was simulated and analyzed by the soil moisture forecast model.The results showed that the crop coefficient was 0.80 and the measured and observed soil moisture value was basically consistent in the whole growing period in 2014.
