摘　　要：[目的]研究意菲乐~?替代尿素追施氮肥对冬小麦产量的影响。[方法]试验设置3个处理:叶面喷雾追施意菲乐~?7.5 L/hm^2、地表撒施尿素112.5 kg/hm^2和不追施任何肥料,分析在冬小麦拔节孕穗期不同处理对冬小麦生长指标、产量构成因素和产量的影响。[结果]喷施意菲乐~?处理的产量为6 130.8 kg/hm^2,增产效果最显著,与撒施尿素相比,产量增加5.02%,产值增加556.53元/hm^2,纯收益增加406.53元/hm^2;产投比表现为意菲乐~?处理>尿素处理>不追施任何肥料。[结论]与撒施尿素相比,叶面喷施意菲乐~?不仅减少了氮肥投入、提高了氮素利用率,还能够显著提高冬小麦的产值、纯收益和产投比。因此,在冬小麦拔节孕穗期,采用意菲乐~?替代尿素追施氮肥对实现现代化农业生产的高产高效、资源节约和生态环境保护具有重要意义。[Objective]Field experimentswere conducted to study Effects of FOLISTIM HUMI-N replacing urea on winter wheat yields by topdressing.[Method ]The experiment was consisted of 3 treatmentsat jointing and booting stage of winter wheat:on 7.5 L/hm^2 FOLISTIM HUMI-N foliar spraying,112.5 kg/hm^2 urea surface spreading and no topdressing.The characteristics of growth index and yield of winter wheat under different fertilization modes were analyzed.[Result]The effect of FOLISTIM HUMI-N foliar spraying was the most significant, and the yield was 6130.8 kg/hm^2.Compared with urea surface spreading,yield increased by 4.96%,yield value increased by 556.53 yuan/hm^2,net income increased by 406.53 yuan/hm^2.Ratio of output to input:FOLISTIM HUMI-N>Urea>No topdressing.[Conclusion]Compared with urea surface spreading, FOLISTIM HUMI-N foliar spraying was not only reduced the input of nitrogen fertilizer and improved the utilization rate of nitrogen,but also significantly improved the output value, net income and the ratio of output to input of winter wheat.Therefore,FOLISTIM HUMI-N as a substitute for urea was beneficial for improving productivity efficiency of agricultural,resources and environmental protection.
