中文摘要:
      采用气压过程分离(BaPS)方法研究了覆膜和裸地(CK)土壤在常规施肥和不施肥条件下的硝化-反硝化速率和呼吸速率,目的是探讨膜下滴灌土壤硝化-反硝化作用及呼吸作用的规律。结果表明:覆膜与裸地土壤在两种施肥水平下的硝化-反硝化速率及呼吸速率都有明显的季节变化;覆膜与裸地两种不同栽培措施的硝化-反硝化速率、呼吸速率差异极显著,在相同栽培措施下,不同施肥处理间的硝化-反硝化、呼吸速率也达极显著水平;硝化-反硝化速率、呼吸速率在不同栽培措施和不同施肥水平下大小排列为:覆膜>裸地,常规施肥>不施肥。可见,农业栽培措施和不同施肥水平对土壤硝化-反硝化及呼吸作用都有一定的影响。
英文摘要:
      As a new technique， BaPS(Barometric Process Separation) system w as int roduced to measure gross nitrification- denitrification rate and soil respiration rate of tw0 different fertilization treatments of mulching plastic film and bare land, and the goal w as to discuss soil nitrification- denit rification and the respira tion rule under mulch drip irrigation. The results show that :Soil nit rification-denit rification rate and respira-tion rate of the two different fertilization treat ments have obvious seasonal variation. The difference of soil nitri-fication-denitrification rate and respiration rate of mulching plastic film and bare land is significant. With the same cultiv ation measures，the difference of soil nit rification denitrification rate and respiration rate between the two fertilization treatments w as extremely significant . The decrease order of soil nit rification-denitrification rate and respiration rate of different cult iv ation measures and fertilization treat ments are arranged as: mulchingplastic film > bare land ; Conventional fertilization> No- fertilization. So，the agricult ural cultivation measure and different fertilization level have certain influence on the soil nit ration-denit rificat ion and respiration.
