摘要
通过田间试验方法,研究并比较3种不同N、P、K配比施肥与当地常规施肥在玉米上的应用效果。试验结果表明,当河淤土区玉米生产的N、P、K适宜配比为N∶P2O5∶K2O=1.0∶0.5∶(0.4～0.5)时,既可增加作物产量,又具有显著的经济效益。
Based on field experiment, this paper studied and compared the growth characteristics and yield of corn between formula fertilization and routine fertilization. The results showed that the formula fertilization increased the corn yields as well as its economic returns when the feasible rate of NPK fertilizers in formula fertilization were N∶P2O5∶K2O=1∶0.5∶（0.4～0.5）.
