摘 要:[Objective] The aim was to select the optimal amount of controlled-release fertilizer and provide theoretical references for controlled-release fertilizers use in summer maize. [Method] Long-term controlled-release fertilizers were applied once at sowing summer maize to explore effects on maize growth, yield, economic profits and environment. [Result] Maize yield reduced a little in the treatment group with 60% CRF, and increased in varying degrees in the rest groups in the range of 1.1%-7.4%, and some showed significant differences. [Conclusion] Controlled-release fertilizers can be applied once at the amount of 80% common fertilizer's, with con- sideration of maize yield, nitrogen use rate and economic profits, which is beneficial for summer maize application and promotion in North China.[目的]筛选出控释肥的最佳适宜用量,为缓控释肥在夏玉米上的应用提供理论依据。[方法]对长效控释肥在夏玉米播种时一次性基施,探讨不同用量的长效控释肥对玉米生长发育、产量、经济效益及环境的影响。[结果]除60%SRF,处理略有减产外,其余处理均表现不同程度的增产,增产率为1.1%~7.4%.部分处理的产量差异达到显著水平。[结论]在该试验条件下,综合考虑玉米产量、氮素利用效率和经济效益,采用普通施肥量的80%水平的控释肥一次施用.可以达到省工、高产、高效、节肥的目的,益于在华北平原夏玉米生产区推广应用。
