| 摘 要： | 为达到适时适量灌溉的目标,利用联合国粮农组织(FAO)推荐的彭曼一蒙特斯公式对参考作物蒸腾量进行逐日推算,以作物蒸腾量及土壤含水量为输入量,灌水量为输出量,使土壤含水量保持在预定范围为目标建立作物需水量模糊控制系统.以北京地区为例对作物需水量计算系统进行了测试,在测试期内,土壤含水率保持在预定范围内.同时考虑了降雨影响,避免降雨时灌溉.

| Abstract: | In order to irrigate at the right time and appropriate quantity,the Penman-Montieth formula,which is recommended by Food and Agriculture Organization(FAO),is used to calculate the Reference Evapotranspiration day by day.Taking the crop evapotranspiration and soil moisture as input factors and the irrigation water as output factor,the fuzzy control system for irrigation water quantity,in which the target is to keep the soil moisture in preconcerted range,is studied in this paper.Taking Beijing district as an... |
