摘　　要：采取"3414"试验设计,以甜糯玉米万糯1号为试材,研究了氮肥、钾肥、密度3因素对甜糯玉米生产的影响。结果表明,随着氮肥施用量增加,鲜穗粗和鲜穗产量呈先增后减的趋势;随着钾肥施用量增加,商品穗长和鲜穗产量增加,鲜穗粗则先增后降;当密度增加时,鲜穗产量增加,但商品穗长和鲜穗粗降低;密度是影响甜糯玉米鲜食商品性的主要风险因素;参试3因素分别与鲜穗粗、商品穗长和鲜穗产量存在显著的函数关系;以标准商品穗长17 cm为目标穗长,通过数学模型模拟分析,获得了万糯1号鲜食商品化最优栽培措施组合,即施用N(130.3±14.3)kg·hm-2,施用K2O(74.4±6.8)kg·hm-2,种植玉米(52 759±1 017)株·hm-2。Adopting ＂3414＂ experiment design, the effects of nitrogen fertilizer, potash fertilizer and density on the sweet-waxy maize with Wan-nuo 1 were studied.The results showed that fresh ear diameter and fresh ear yield firstly increased and then decreased with the increase of nitrogen. With the increase Of applying potash fertilizer, commercial ear length and fresh ear yield increased, fresh ear diameter firstly increased and then droped. When the density increased, the fresh ear yield increased, but the commercial ear length and fresh ear diameter decreased. Density was the main risk factors affecting the commodity of the fresh sweet-waxy maize. There were significant function relations between three factors and fresh ear diameter, commercial ear length and fresh ear yield respectively. To aim at standard commodity ear length of 17 era, with the mathematical model for the simulation analysis, the optimal combination cultivation measures was obtained,and it was N （130.3 ± 14.3） kg· hm-2, K2O （74.4±6.8） kg. hm-2, （52 759±1 017） plants · hm-2.
