[目的]为了研究玉米最佳施肥方式及肥料种类。[方法]以郑单958为材料,研究了4种不同缓控释型肥料处理下玉米不同时期干重、产量及肥料贡献率的变化。[结果]各处理间玉米净增产量及肥料贡献率均达到0.05水平显著性差异,高低顺序为明泉控释肥>洋丰复合肥>杰翔复合肥>辽中京>CK。缓控释肥料处理的叶面积系数及不同生育时期植株干重占总重的百分比均高于对照。[结论]缓控释肥效果表现最好,其中明泉控释肥表现最突出,其次是洋丰复合肥。
[Objective] In order to study the best maize fertilization and fertilizer types. [Method] With Zhengdan 958 as material, the changes of dry weight, yield and fertilizer contribution rate of maize under different slow-release controlled-release fertilizers were studied. [Result] The net yield of maize and the contribution rate of fertilizers between the treatments all reached the significant difference of 0.05 level. The sequence of high and low fertilizers was controlled release fertilizer of Mingquan> Yangfeng compound fertilizer> Jiexiang compound fertilizer> Liaozhongjing> CK. Controlled-release fertilizer treatment of leaf area coefficient and different growth stages of plant dry weight accounted for the total weight percentage were higher than the control. [Conclusion] The controlled release fertilizer had the best performance, of which the controlled release fertilizer of Mingquan had the most outstanding performance, followed by Yangfeng Compound Fertilizer.
