运用乙炔抑制-静态土柱培养法测定旱地土壤氮素反硝化损失

Measurement of Denitrification in Upland Field Using Acetylene Inhibition- Static soil Core Incubation System

介绍了测定土壤反硝化作用的乙炔抑制 -静态土柱培养法 ,并就其应用中的一些条件进行了说明 ,内容包括土柱的取样深度、土柱取样量、土柱培养方式及基本操作程序等。最后阐述了这一方法在北京郊区土壤上的使用情况。

This paper introduces a static soil core incubation system for the measurement of upland field denitrification using acetylene inhibition, and it discusses some aspects in application of this method,including soil core collection, incubation and other procedures. Finally it gives a brief introduction to denitrification study using this method in Beijing surburb presently.
