摘  要：
通过对黑龙江海伦农业生态实验站的空间移位长期定位试验的5种有机质含量的农田黑土研究表明,土壤微生物量碳、氮随土壤有机质含量的增加而增加,且有机质含量最高的北安(SOM11)与其它4个处理差异达到显著水平。对玉米拔节期、灌浆期、成熟收获期土壤微生物量碳、氮测定表明,拔节期最高,灌浆期最低。土壤转化酶活性、过氧化氢酶活性的测定表明,2种土壤酶活性随土壤有机质含量的增加而增加,但是差异不显著。在玉米的生育内,两种土壤酶活性变化规律为拔节期较高,到灌浆期降到最低,收获期又升到最高。

摘  要：
The relationship among organic matter content and soil microbial biomass C or N and soil enzymes activities were investigated for farmland black soil of long-term specific-site experiment about space removal of 5 kinds of soils with different organic matter contents. The results showed that soil microbial biomass C and N increased with the adding of soil organic matter content and significantly differed in the soil of Bean with the highest organic matter content and those of other 4 soils with different organic matter. Soil microbial biomass C and N were the highest at jointing stage and the lowest for gain-filling stage in the growth stages of maize. Soil invertase and catalase activities enhanced with the increasing of soil organic matter content, and there were no obvious differences for different soils. In the growth stages of maize, the changes of 2 soil enzymes patterned as: higher at jointing stage, falling to the lowest at grain-filling stage and turning to the highest at harvest stage.
