[目的]为了解脲铵氮肥在玉米生产上的应用效果。[方法]以夏玉米为试验材料,通过田间小区试验,研究了脲铵氮肥对玉米产量及产量构成因素的影响。[结果]脲铵氮肥肥效长,具有和尿素一样的增产效果,能明显改善玉米农艺性状和经济性状,增加产量,并且,脲铵氮肥养分减量40%施用(即只需使用纯氮60%的等量脲铵氮肥),就与尿素常规传统施肥方式取得相同的增产效果,投产比高经济效益显著。[结论]为脲铵氮肥大面积推广应用提供科学的理论指导。
[Objective] The aim was to find out the application effect of urea ammonium nitrogen fertilizer on corn production. [Method] With summer maize as experimental material, field trials were conducted to study the effects of urea ammonium nitrogen fertilizer on the yield and yield components of maize. [Result] Urea-urea nitrogen fertilizer had the advantages of long-term efficiency, yielding the same stimulation effect as that of urea, significantly improving the agronomic traits and economic traits of corn, and increasing the yield. Moreover, the urea ammonium nitrogen fertilizer was reduced by 40% Of the same amount of urea ammonium nitrogen fertilizer), urea and conventional fertilization on the same way to achieve the same effect of increasing production, high economic efficiency significantly. [Conclusion] This provided scientific theoretical guidance for the popularization and application of UFN over large area.
