摘要 【目的】研究化肥配施有机肥的条件下,分析有机无机配施对玉米生长与营养状况,为玉米减施增效提供技术支撑。【方法】设5个处理,3次重复,CK:不施肥;PK:施用磷钾肥,不施氮肥;NPK:施用氮磷钾肥;NPKZn:施用氮磷钾肥和锌肥;NPKM:施用氮磷钾肥和有机肥。【结果】与常规施肥相比,化肥配施有机肥提高了玉米产量,平均增产6.5%,N素吸收量增加4.5%,籽粒Zn浓度增加3.25 mg/kg。【结论】化肥配施有机肥可以显著提高玉米产量、N素吸收量和籽粒Zn浓度,是化肥减施增效的有效措施。 【Objective】To regulated the growth and nutritional status of maize during the application period of N,P and K under the condition of chemical fertilizer combined with organic fertilizer in the hope of providing technical support for reducing application and increasing efficiency of maize.【Methods】Five treatments were set up and repeated for 3 times,CK:no fertilization;PK:apply phosphorus and potassium fertilizer without nitrogen fertilizer;NPK:apply nitrogen,phosphorus and potassium fertilizer;NPKZn:apply nitrogen,phosphorus,potassium and zinc fertilizer;NPKM:apply nitrogen,phosphorus,potassium fertilizer and organic fertilizer.【Result】The two-year experiment showed that compared with farmers'customary fertilization,chemical fertilizer combined with organic fertilizer increased corn yield by 6.5%,N absorption by 4.5%and grain Zn concentration by 3.3 mg/kg.【Conclusion】The combination of chemical fertilizer and organic fertilizer can significantly increase maize yield,N absorption and Zn concentration in grain,which is an effective measure to reduce the application of chemical fertilizer.
