摘　　要：为寻找适宜鲜食甜糯玉米水肥一体化生产的水肥耦合参数,采用大田试验研究了不同施肥水平条件下(60%～100%施肥水平)水肥一体化技术对鲜食甜糯玉米生长特性与产量的影响。结果表明,与常规施肥相比,水肥一体化施肥处理的鲜食甜糯玉米不同生育期株高与叶面积分别平均提高4.30%和7.66%,鲜苞产量、鲜秸秆产量、总产值分别平均提高2.96%、9.44%、3.51%,其中70%水肥一体化施肥的玉米鲜苞产量、产值分别提高6.73%、6.72%。可见,在一定的土壤肥力条件下,70%水肥一体化处理的施肥量是一个比较适宜的水肥耦合参数,可用于指导鲜食甜糯玉米水肥一体化生产。A field experiment was conducted to study the effect of integrated irrigation and fertilizer management on growth characteristics and yield of fresh-consumable sweet-waxy maize. Different fertilization levels （60-100% of those used as conventional fertilizer） were used in order to find out a suitable combination of water and fertilizer for production of fresh-consumable sweet-waxy maize. Compared with conventional fertilization, the combined application of irrigation and fertilizer at different fertilization levels, increased plant height and leaf area of fresh-consumable sweet-waxy maize at different growth stages by 4.30 and 7.66%, respectively, and enhanced the fresh corn-bract yield, fresh stalk yield and gross output by 2.96, 9.44 and 3.51%, respectively. The fresh corn-bract yield and gross output recorded a marked increase of 6.73 and 6.73%, respectively in the combined irrigation and fertilizer treatment （70% of conventional fertilizer）. Therefore, use of 70% of conventional fertilizer combined with irrigation seems to be a good practice for production of fresh-consumable sweet-waxy maize under certain soil fertility condition.
