In recent years , the water - saving and control irrigation technique of rice has diverted from plot experimental and demonstration to lare scale . and has got remarkable economic and social benefits . amed at the characteristics of this irrigation area , optimal selection for water - saving techniques of rice , deciding the amout of leaching water and irrigation modles , investigating the adaptability of the water - saving and control irrigation technique in saline land . studying the increase in production mechanism of the technique are important to extend the technique , to better and develop saline land as well as slick spots . according to the results of field experiments , optimization study was conducted on the water - saving irrigation technique of rice in saline land , the effects of different water - saving irrigation techniques on the physiological indexes and yield of rice were systematically analyzed . by using mutiplepurpose fuzzy optimization method , better . water - saving irrigation technique was selector out , that is . the control irrigation technique in rice . the mechanism of it was analyzed from the aspect of the physiological and ecological saving water of rice to provide the implemental process and technical point ; throgh the quantitive analysis and comparision on control irrigation and control class ( flood irrigation ) , high production and quality mechanism of the technique was analyzed in terms of physiology indexes of rice , the variation of soil moisture , the pest resistance and the lodge resistance , the change of soil temperature in paddy fields . the yield constitutive factors , the quality of rice and so on . in saline land . control irrigation and intermittent leaching modles were adopted to validate the adaptability of the technique in irrigation of rice in saline land , to analyze rice ' s physiological - ecological indexes and the change of soil salt content under the conditions of control irrigation leaching of rice and and to provide control irrigation and combined modle of intermittent leaching to adapt to different conditions 本文从试验及试验资料入手，取得以下主要成果和结论：对盐碱地水稻节水灌溉技术进行优化研究，系统地分析了不同节水灌溉技术对水稻生理指标及产量的影响，采用了多目标模糊优化的方法，对灌水技术进行综合评判，优选了节水灌溉技术，论证该地区宜采用水稻控制灌溉技术；阐述控灌技术通过调节和控制水稻的需水规律，降低水稻高产情况下的无效水量消耗，从水稻生理、生态节水两方面分析了控灌技术节水机理，针对性地总结出水稻各生育期实施节水控灌技术的步骤及技术要点；通过控灌与淹灌的定量对照比较，从根系、茎蘖、冠层叶片及绿叶动态到株高，土壤水分变化，抗病虫害、抗倒伏能力，稻田土温变化，产量构成因素及稻米品质等诸多方面进行动态比较，分析控灌技术高产优质机理；在盐碱稻地采用控制灌溉+间歇淋洗模式，跟踪测试田间水盐变化状况，验证控制灌溉技术在盐碱地区水稻灌溉中应用的适应性，通过分析水稻控制灌溉淋洗条件下水稻生理生态指标，提出优化控制灌溉+间歇淋洗组合模式，为进一步在高矿化度地区试验水稻控灌技术奠定基础。
