摘要: 【目的】提高玉米氮肥利用率,以达到最佳增产效果。【方法】 采用随机区组设计,对河套灌区一穴双株高产栽培模式下不同施氮处理对玉米生长和产量的影响进行了研究。【结果】 玉米施氮肥后增产显著,氮肥后移比农民习惯施肥增产6.8%~27.3%,氮肥后移有利于玉米穗位叶在生育后期保持较高的叶面积指数及SPAD值,进而提升玉米的产量。【结论】 处理2(30%种肥,35%小喇叭口期,25%大喇叭口期,10%灌浆期)施用氮肥的产量最高,表现较好,该施用方式为实现玉米合理施肥提供了依据。

Abstract: 【Objective】Improve nitrogen use efficiency of maize to achieve the optimum yield. 【Methods】Using a random block group design,the effects of different nitrogen fertilizer application treatments on the growth and yield of maize in the high-yield one-hole double-plant cultivation model in the Hetao Irrigation District were studied.【Results】The yield of nitrogen fertilizer was increased by 6.8%-27.3% after the application of nitrogen fertilizer and the proper removal of the nitrogen fertilizer was beneficial to the higher leaf area index and SPAD value in the later stage of the growth of maize,and the yield of maize was increased. 【Conclusion】The yield of treatment 2 was the highest in the “30% seed fertilizer,35% small bell-mouth stage,25% big bell-mouth stage,10% grouting stage” nitrogen fertilizer application mode,and the performance is good. The application model provides a basis for rational fertilization of maize.
