摘　　要：在胶东大田条件下,以烟农21号小麦为试验材料,通过DTOPSIS法将6种灌溉模式下小麦的有效小穗数、无效小穗数、穗粒数、千粒重、666.7m2穗数、产量、生物产量、经济产量和经济系数等性状指标归纳为一个具有可比性的量化综合指标,对灌水模式进行综合评价。Ci值最大的为灌溉模式1,为0.6933;其次为灌溉模式5,为0.5386。根据小麦各灌溉模式的Ci值,在该试验条件下,最适宜鲁东半岛地区的为灌溉模式1,即灌溉底墒水+拔节水。Under field condition in eastern Shandong Province, using wheat variety Yannong 21 as mate-rial, its character indexes, containing effective spikelet, ineffective spikelet, grain number per spike, 1 000 - grain weight, spike number per 666.7m^2, yield, biological yield, eeonomic yield, economic coefficient and so on, under 6 different irrigation modes were reduced to an comparable quantized comprehensive index respec-tively by Dynamic Technique for Order Preference by Similarity to Ideal Solution （DTOPSIS） method to com-prehensively evaluate wheat irrigation modes. The Ci value under irrigation mode 1 was the biggest of 0.6933, followed by that under irrigation mode 5 of 0.5386. Under the experiment condition, according to Ci value un-der different irrigation modes, the optimum irrigation mode for peninsula area in eastern Shandong Province was irrigation mode 1, irrigating before sowing and at jointing stage.
