Nitrous oxide (N2O) emissions and the change of microbial biomass and their community by green manure incorporation was investigated. Further studies on different green input method (incorporation or mulching) and biochar application were conducted to reduce the N2O emmision. N2O emission was high when easily decomposed green manure (low CN ratio) was incorporated, and gram negative bacteria biomass was positively correlated to N2O emission. Mulch treatment reduced N2O emission compared with incorporation method. Biochar treatment clearly reduced N2O emission. One of the reason for this N2O reduction by biochar was thought to be due to microbial community change i.e. biochar treatment decreased gram negative bacteria while increased fungi.

研究了绿色肥还田过程中氮氧化物（N2O）的排放和微生物量及其群落结构的变化。进一步研究了不同的绿色投入方式（掺入或覆盖）和施用生物炭对减少N2O排放的影响。易腐绿色肥（低CN比）的施用有利于N2O的排放，且革兰氏阴性菌生物量与N2O排放量呈正相关。与掺入法相比，覆盖处理降低了N2O的排放。生物炭处理明显降低了N2O排放。生物炭减少N2O的原因之一被认为是由于微生物群落的变化，即生物炭处理减少了革兰氏阴性细菌，而增加了真菌。
