摘　　要：通过2年田间定位试验,研究不同培肥方式（常规栽培T1、深松T2、深松＋深施肥T3、综合培肥T4）对春玉米氮、磷、钾养分积累及产量构成的影响。结果表明,T3、T4处理增产效果显著,与常规栽培（T1）相比,分别增产8.9%~16.5%,9.2%~18.1%。此外,T3、T4处理显著增加植株氮、磷、钾的累积,与T1相比,2个处理植株氮素积累量分别增加9.8%~17.0%,13.6%~26.2%,磷素积累量分别增加7.2%~11.2%,14.3%~21.6%;且2个处理氮、磷增量多集中于籽粒,T3、T4处理籽粒中氮积累量较T1的增幅分别为21.7%~25.1%,29.0%~39.5%,磷积累量的增幅分别5.6%~20.1%,11.2%~33.0%。A two-year experiment was conducted to investigated the effects of different fertilizer methods（conventional cultivation T1,subsoiling tillage T2,subsoiling tillage and deep fertilizer application T3,and integrated fertilizer application T4）on accumulation of N,P and K nutrients,grain yields and its components of spring maize.The results indicated that the grain yield significantly increased by 8.9%~16.5%and 9.2%~18.1%in T3 and T4treatments compared with conventional cultivation（T1）.Besides,the accumulations of N increased by 9.8%~17.0%and 13.6%~26.2%in T3 and T4treatments,respectively.The accumulation of P increased by 7.2%~11.2%and 14.3%~21.6%,respectively.Most of N and P were accumulated in grain.The N in grain of T3 and T4treatments increased by 21.7%~25.1%,29.0%~39.5%,and the P in grain increased 5.6%~20.1%,11.2%~33.0%,compared to T1 treatment.
