摘　　要：控制性交替灌溉技术是一种新兴灌溉技术。本文采用蒸渗仪对沈阳地区潮棕壤土条件下的玉米在不同控制性交替灌溉处理下的生长发育、生理生态指标、产量及其构成因子、水分利用率和经济效益进行分析,提出了适合当地条件的玉米优化控制性交替灌溉制度,为该技术在东北地区的推广和应用提供理论依据。Controlled alternative irrigation is high cost of equipment, but can obtain high yield. gation in Northeast. So, in this study, the maize a rising technology of water-saving irrigation, which doesn＇t require However, there were few of researches on controlled alternative irrigrowth, eco-physiological Indices, yield and economic benefit etc. were studied with lysimeters of fluvo-aquic brown soil under different controlled alternative irrigation scheduling, in Shenyang region. The optimized irrigation scheduling of controlled alternative irrigation for maize suitable for this regional and soil condition was found. These researches provided a theory base for the popularization and application of controlled alternative irrigation in Shenyang and the Northeast region.

关 键 词：控制性交替灌溉 产量 水分生产率 灌溉制度
