| 摘 要： | 通过盆栽试验,研究不同缓/控释肥一次性施用对玉米氮素吸收和土壤速效氮的影响。结果表明,与不施氮处理相比,施用氮肥具有显著增产效果。相同施氮量条件下,一次性施用不同类型的缓/控释肥的产量之间存在显著差异。"乐喜施"、"鲁西化工"处理的产量显著高于"金正大"和"益多保"处理,增产达7.3%~11.8%。成熟期,"乐喜施"、"鲁西化工"和"益多保"处理的植株氮素积累量显著高于"金正大"和"施可丰"处理。缓/控释肥在土壤中的氮素释放天数在60 d左右,释放高峰在播种后32 d前后,之后土壤速效氮含量呈下降趋势。

| Abstract: | The pot experiment was carried out to study the effect of maize nitrogen uptake and soil available N in several styles slow/controlled release fertilizers one time application. The result showed that, compared with N0 treatment, the nitrogen fertilizer application increases the yields significantly. Under the same N fertilizer application amount, the yield of one-time application different styles slow/controlled release fertilizer has a significant difference. Yield that by Lexishi and Luxihuagong treatments was significantly higher than Jinzhengda and Yiduobao by 18.7%-21.14%. In mature, the plant N accumulation of Lexishi, Luxihuagong and Yiduobao was higher than Jinzhengda and Shikefeng significantly. These slow/controlled release fertilizer release available N in soil about 60 days, the peak of release was before and after 32 days after planting, and then, soil available N content appeared a decreasing trend. |
