| 摘 要： | 以东农253玉米品种为材料，采用分层施肥方法，研究种肥深度变化对东北北部春玉米氮磷钾吸收及产量的影响。结果表明，种肥深度对玉米植株氮磷钾积累量影响较大，在苗期氮磷钾积累量以种肥同层（D0）和种下6 cm（D-6）处理较高；成熟期以种肥同层（D0）、种下6 cm（D-6）、种下12 cm（D-12）处理较高。玉米植株干物质量及产量与种肥深度呈单峰曲线变化趋势，玉米植株苗期和成熟期干物质量以种下6 cm（D-6）和种下12 cm（D-12）处理较高；玉米产量以种下12 cm（D-12）处理最高，但与种肥同层（D0）、种下6 cm（D-6）处理差异不显著，显著高于种下18 cm（D-18）、种下24 cm（D-24）和不施肥（对照）。种子与肥料同层条件下会影响玉米的出苗和干物质积累量，种肥施于种下3 cm以上时，对玉米出苗及干物质积累量无明显影响，种肥的适宜深度为种下3~12 cm。

| Abstract: | Used DN253 as the experimental material, the effect of fertilization depth on N,P,K absorption and yield of corn was researched. The result showed that the fertilization depth had a greater impact on the content and accumulation of N,P,K and in the seeding stage, the content and accumulation of N,P,K were the largest in D0, D-6 treatments, in maturity stage, the content and accumulation of N,P,K were the largest in D0, D-6, D-12 treatments; ac-cumulation of dry matter and yield showed unimodal trend with fertilization depth, the accumulation of dry matter and yield were higher in D-6, D-12 treatments, yield were the largest in D-12 treatment, but not significant with the treatments of D0, D-6, significantly higher than the D-18, D-24 and CK. Fertilization from the same depth with seeds af-fected seedlings emergence,distance between fertilizer and seeds deeper than 3 cm had no significant effect on the emergence of corn, the suitable fertilization depth should be 3-12 cm under the seeds. |
