摘　　要：根据文献资料 ,从作物地下与地上部生长发育、根系吸收性能、作物水分生理状况、隔沟灌溉条件下的水流推进与入渗、作物产量及水分利用效率等几个方面 ,概述了控制性交替灌溉技术研究的历史、动态及一些主要研究成果 ,分析了该技术在实施过程中可能遇到的一些问题及相应的解决办法。最后 ,针对我国具体国情 ,对交替隔沟灌溉技术需进一步深入研究的几个问题进行了探讨。According to the information of literature,this paper traces the historical development of studies on the adoption of the controlled alternate irrigation techniques concerned at home and abroad. The main researches were summarized. Some problems in the implementation of this technique were analized, from the aspects of the growth and development of the parts both under soil surface and above soil surface,the root absorbing properties, the water physiological status of crop, the advancing rate and intake of water as well as yield and water use efficiency under alternate furrow irrigation, etc. Finally, some problems for further study are discussed according to the practical situation in China.
