Abstract: To seek a scientific pattern for reducing fertilization in Beijing, we conducted a field experiment with reduced controlled-release blended fertilizer replacing chemical nitrogen fertilizer, and analyzed its effects on of fresh maize yield, nitrogen fertilizer utilization efficiency and soil nitrate nitrogen. To ensure the extension of the experimental within Beijing and understand the effects of soil temperature and rainfall on controlled-release nitrogen, we selected two medium fertility plots in Pinggu and Miyun (called plot A and plot B) with five nitrogen (N) treatments: no fertilizer (CK), recommended fertilization (OPT), 3 controlled -release blended fertilizer levels (CRU1, CRU2, CRU3, which denotes 0, 10% and 20% reduction of N rate based on OPT, respectively). We investigated fresh maize yield, economic benefit, nitrogen fertilizer utilization efficiency, nitrogen accumulation amount and soil nitrate nitrogen. The results showed that, the yield of fresh maize was in the order of CRU1>CRU2, CRU3, OPT>CK, and CRU1 had the highest yield. The yield of CRU was 750 – 758 kg·hm⁻² (plot A) and 1 500 – 1667 kg·hm⁻² (plot B) higher than that of CRU2 and CRU3, and increased 3.15% – 17.1% (plot A) and 3.54% – 10.1% (plot B) compared with OPT, respectively. The income was in the order CRU1>CRU2>CRU3>OPT>CK, and CRU1 had the highest income, the profit of CRU1 was 3 690 − 3762 yuan (plot A), 7 470 – 8273 yuan (plot B) higher than that of CRU2 and CRU3, and increased 5.75% – 12.8% (plot A) and 5.31% – 20.2% (plot B) compared with OPT, respectively. CRU treatments improved the nitrogen fertilizer utilization efficiency compared with OPT; the difference between CRU3 and OPT was with the largest recovery efficiency of N and partical-factor productivity of N; the difference between CRU1 and OPT was with the largest agronomic efficiency of N. These results indicated that compared with urea multi-fertilization, the controlled-release blended fertilizer single application improved the yield of fresh maize, increased income and nitrogen fertilizer utilization efficiency, while application of 180 kg(N)·hm⁻² reached the highest yield and income. In this study, the soil nitrate nitrogen in 0 – 20 cm layer, the peak of CRU was with 83.0 – 105 mg·kg⁻¹ (plot A) > 67.9 – 79.1 mg·kg⁻¹ (plot B) within 24th day, and the peak in plot A was higher than that in plot B due to the higher soil temperature and stronger rainfall in plot B resulted in excessive and early release of controlled-release nitrogen. The peak of OPT appeared again on the 48th day, and plot B was in the order of OPT > CRU, there were no difference between these two treatments in plot A; which indicated that soil temperature and rainfall in plot A relatively ensured the slow release of controlled-release nitrogen, the nitrogen supply in the later period of crop was ensured. 20 – 60 cm soil layer had the similar pattern, indicating a leaching risk of nitrate nitrogen into the deep soil.
