摘要
[目的]筛选与淮北地区土壤特征和玉米栽培条件相适应的玉米专用肥。[方法]通过设置不施肥( CK)、农民习惯施肥、高氮复合肥和控释尿素玉米专用BB肥4个处理，研究不同肥料及施肥方式对玉米农艺性状和产量的影响。[结果]比对照相比，各施肥处理均能有效提高玉米株高、茎粗、产量、生物量和经济系数，各施肥处理之间产量无显著差异。[结论]从农事操作来看，高氮复合肥和控释尿素玉米专用BB肥更易于推广应用。
Abstract
Objective] To screen the proper fertilizer for maize suitable for soil characteristics in Huaibei Area and the cultivation condition for maize. [ Method] Four treatments were designed, which were no fertilization ( CK) , farmer conventional fertilization, high-nitrogen com-pound fertilizer, and maize specialized BB fertilizer of controlled release urea. [ Result] Compared with the control, all the fertilization treat-ments enhanced the maize yield, plant height, stem width, biomass and economic coefficient. There were no significant differences in yields between fertilization treatments. [ Conclusion] As for farm operation, high-nitrogen compound fertilizer and maize specialized BB fertilizer of controlled release urea are more suitable for extension and application.
