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 was introduced to measure gross nitrification-denitrification rate and soil respiration rate of two different fertilization treatments of mulching plastic-film and bare land,and the goal was to discuss soil nitrification-denitrification and the respiration rule under mulch drip irrigation.The results show that:Soil nitrification-denitrification rate and respiration rate of the two different fertilization treatments have obvious seasonal variation.The difference of soil nitrification-denitrification rate and respiration rate of mulching plastic-film and bare land is significant.With the same cultivation measures,the difference of soil nitrification-denitrification rate and respiration rate between the two fertilization treatments was extremely significant.The decrease order of soil nitrification-denitrification rate and respiration rate of different cultivation measures and fertilization treatments are arranged as: mulching plastic-film >bare land;Conventional fertilization>No-fertilization.So, the agricultural cultivation measure and different fertilization level have certain influence on the soil nitration-denitrification and respiration.
