摘　　要：通过比较分析不同节水模式对玉米产量的影响,探索出通辽市气候条件下玉米最佳节水模式及适宜的灌水量。采用不同灌水量下无膜浅埋滴灌(SI)、普通管灌(PI)及膜下滴灌(DI)的对比试验,分析了不同节水模式下的产量与节水效果的关系,结果表明:不同节水模式玉米产量排序为DI总灌水量235 mm>SI总灌水量235 mm>SI总灌水量300 mm>SI总灌水量170 mm>PI总灌水量280 mm>SI总灌水量105 mm>SI总灌水量40 mm;其中以SI总灌水量235 mm为最佳模式,播种至成熟期总需水量为505.2 mm,与PI相比节水45 mm,节水率达到16.07%,与DI相比减少了地膜使用,实现零污染。The best water-saving model and the appropriate irrigation amount of maize was explored under the climate condition in Tongliao by comparing and analyzing the effects of different water-saving models on maize yield.The relationship between maize yield and water-saving effect under different water-saving model s were analyzed according to contrast experiment of shallow subsurface drip irrigation without mulch(SI),pipe irrigation(PI)and drip irrigation under mulch(DI).The results showed that the sort of maize yields under different water-saving models was DI 235 mm>SI 235 mm>SI 300 mm>SI 170 mm>PI 280 mm>SI 105 mm>SI 40mm.SI 235 mm was the best water-saving model,and the total water requirement from sowing to maturity was 505.2 mm,the total water drop is 235.0 mm.SI 235mm had water conservation 45 mm,and the saving water rate was 16.07%compared with PI;the cost of mulch was also saved compared with DI,thereby realizing zero pollution.
