摘　　要：本文采用四种相对成熟的灌溉模式,通过土壤含水率传感器、温度传感器、植株体电阻传感器,现场实时监测取得水稻在返青、分蘖、拔节孕穗、抽穗开花、灌浆及黄熟期等不同的生育期的水稻生长土壤含水率、温差、体电阻等信息和实际科学的需水量信息。水稻节水灌溉控制决策依据阀值控制。本研究的水稻需水模型的建立是从实验数据入手,由于实验数据是现场实时采集的数据,这些数据是综合考虑实际的各种影响因素,基于这种方法对数据进行融合建立起来的节水灌溉决策模型,具有真实、可靠等特点。In this paper, The four relative mature water saving irrigation model were adopted. Hired sensor of soil moisture content ,temperature transducer and crop resistance sensor, gained real - time data acquisition and scientific information of crop consumptive use of water in the field at different rice growing stages （ rice green again, tiller , booting,tassel, in the milk,stage of yellow） . The rice of water saving irrigation of control deeisionhas has come true according to spot val- ue. Builded water saving irrigation model based on the experimental method, it is ensuring truthful and reliable, because of comprehensive consideration of many influencing factors.
