摘要:
为了解膜下滴灌土壤硝化、反硝化作用的变化规律,应用气压过程分离(Barometric process separation,BaPS)方法,研究了施氮肥、有机肥与氮肥配施和不施肥3种不同施肥处理的土壤硝化、反硝化速率在覆膜与裸地条件下的动态变化。结果显示,不同处理下土壤硝化、反硝化作用随着玉米生育期的推移有明显的变化。相同栽培措施不同施肥处理间土壤硝化、反硝化速率差异均达极显著水平,且大小顺序为氮+有机肥配施处理>施氮肥处理>不施肥处理(对照);相同施肥处理不同栽培措施间土壤硝化、反硝化速率大小顺序均为覆膜处理>裸地处理。
Abstract:
To study soil nitrification and denitrification under plastic film drip irrigation, the barometric process separation (BaPS) method was introduced to measure dynamic change of gross nitrification and denitrification rates in three different fertilization treatments, nitrogen(N) application, organic fertilizer combining nitrogen(N+OF) application and no fertilization(CK) with or without muching. The results showed that soil nitrification-denitrification changed greatly over maize growth periods. Nitrification rate and denitrification rate differed in three fertilization treatments with or without mulching. The soil with treatment of N+OF exhibited the fastest nitrification and denitrification rates, followed by N treatment. The nitrification and denitrification rates were higher in plastic film-mulched soil than those in non-mulched soil in the same fertilization treatment.
