摘　　要：为了探明玉米产量形成特性、经济效益及灌溉增产潜力对灌溉的响应,为吉林省西部半干旱区灌溉增产提供理论依据。研究4个灌溉定额下玉米产量、农艺性状和经济效益的变化,并利用Hybrid-Maize模型模拟了这一地区玉米的灌溉增产潜力。结果表明:120 mm(Q1)、170 mm(Q2)和250 mm(Q3)处理的玉米产量均显著高于50 mm(Q0)处理;Q2与Q3处理的叶面积指数(LAI)和株高均显著高于Q0处理;玉米的气候生产潜力值与Q2和Q3处理的实测产量差异较小,与Q0处理的实测产量差异较大,所有处理的实测产量均与光温生产潜力值差异较大。170 mm可作为吉林省西部半干旱地区玉米生产的灌溉参考值,Hybrid-Maize模型可作为预测吉林省西部半干旱区玉米产量变化趋势的模型。In order to explore the characteristics of maize yield formation,economic benefit and the response of irrigation potential to irrigation to provided theoretical basis for irrigation yield increase in the semi-arid area of western Jilin province,the change of maize yield,agronomic character and economic benefit under four irrigation quotas was studied.The Hybrid-maize model was used to simulate the potential yield increase of maize in this area.The results showed that the yield of the treatment of 120 mm(Q1),170 mm(Q2)and 250 mm(Q3)were significantly higher than that of the treatment of 50 mm(Q0).The LAI and plant height of Q2 and Q3 treatment were significantly higher than that of Q0 treatment.The difference between the climatic production potential value of maize and the measured yield of Q2 and Q3 treatment was small,while the climatic production potential value of maize and the measured yield of Q0 treatment was large,and the measured yield of all treatments was significantly different from the production potential value of light temperature.So 170 mm can be used as irrigation reference value for corn production in semi-arid area in the west of Jilin province and the Hybrid-Maize model can be used to predict the variation trend of maize yield in semi-arid area of western Jilin province.
