摘　　要：为了研究调亏灌溉对东北春玉米生长和产量的综合影响，在移动式遮雨棚下，以东北春玉米为试验材料，采用测筒栽培试验方法，分析了玉米在苗期、拔节期、抽雄期中度调亏灌溉处理后对玉米干物质重、耗水量的影响，并采用实码加速免疫遗传算法进行投影寻踪建模，综合评价灌水方案优劣，结果表明：苗期亏水使玉米具有较强的适应干旱的能力，苗期可中度亏水，即控制土壤水分到田间持水量的50％～60％，且苗期调亏的方案经模型评价要优于其它方案。In order to research the comprehensive effects of regulated deficit irrigation to growth and yield of spring maize in northeast China ,under the mobile awning ,taking the spring maize of northeast China as experiment material , the effect of moderate regulated deficit treatment to the dry weight and water consumption in seedling stage ,jointing stage and heading stage of maize was analyzed by using the cylinder cultivation experiment method .Also carried out the projec-tion pursuit establishing model and comprehensive evaluation by adopted the real coded accelerating immune genetic algo-rithm .The result showed that：The water deficit in seedling stage ,the maize will be had strong adaptability to drought , so in seedling stage ,the water deficit can be moderated with 50% to 60% of field capacity ,and the scheme of water deficit in seedling stage will be better than other schemes according to the model evaluation .
