大田试验研究了一次性施用缓控释复合肥对春玉米产量及氮素积累转运的影响。结果表明，一次性施用缓控释复合肥与农户一次性追肥（CK）相比，产量差异不显著；花粒期植株地上部干物质积累量、营养器官干物质转运量和对籽粒的贡献率差异显著,籽粒干物质积累量差异不显著；提高了花粒期植株地上部氮素积累量；氮肥利用效率、氮肥偏生产力、氮肥生理效率差异不显著；对氮肥吸收效率而言，缓控释肥显著高于CK,而磷肥偏生产力、钾肥偏生产力显著低于CK；干物质、氮素积累量、产量三者之间存在显著的相关性。

Based on the fiel d experiment, the effect of the one-time use of sustained release compound fertilizer on product and the nitrogen accumulation and transport of spring maize were analysed .The results showed that, compared to conventional fertilization (CK )and one-time use of sustained release compound fertilizer, the product was no significant difference. Dry matters accumulations of flowing period、Nutritive organ DMA transport、Contribution rate to grain was significant difference, Dry matters accumulations of grain was no significant difference.Improving nutrient accumulations at flowering period;NUE、NPFP、NIE have no significant difference, NRE of one-time use of sustained release compound fertilizer significantly higher than CK.,but PPFP、KPFP significantly were lower than CK, between the three dry matters accumulations、nitrogen accumulation and yield do regression equation,there was close correlation.
