通过田间小区试验,研究不同氮肥处理对双季稻稻田氨挥发及其动力学特性的影响。结果表明:增施氮肥处理与不施氮肥处理比较,增施氮肥促进双季稻稻田氨挥发,且早稻中普通尿素处理、等氮量控释氮肥处理均达显著差异水平,晚稻中除控释氮肥减氮30%处理外均差异显著;控释氮肥处理与普通尿素处理比较,控释氮肥处理双季稻氨挥发通量峰值低于普通尿素处理,且氨挥发损失量早稻控释氮肥处理比普通尿素处理低42. 98%?54. 26%,晚稻降低27. 84%?35. 27% ;不同用量控释氮肥间比较,双季稻稻田氨挥发量随氮肥用量的增加而增加。动力学特性方面,与Elovich方程相比抛物线扩散方程对稻田氨挥发累积量随时间变化的拟合...

Field plot experiment was conducted to study the effects of different nitrogen fertilizers on ammonia volatilization and its dynamic characteristics of double cropping rice. Results showed that compared with control treatment, the total amount of ammonia volatilization increased by supplied nitrogen fertilizer, even the common urea treatment and controlled release nitrogen fertilizer were of significant difference in early rice. All other treatments except reducing nitrogen 30% were significantly different in late season. Comparison between dif...
