metabolic quotient meaning in Chinese
代谢商
Examples
- Soil microbial biomass carbon , microbial biomass nitrogen , soil basal respiration and metabolic quotient all showed a decreasing trend under more than 15 mg . kg - 1 cadmium or more than 200 mg . kg - 1 lead , respectively . soil dehydrogenase , urease and acid phosphotase activities have a significant decrease , and the activities of soil catalase and invertase taking sencond place , while soil protease activities showed stable state
随重金属浓度增加，各指标下降幅度各有差别，其中微生物生物量碳、微生物生物量氮以及基础呼吸和微生物代谢商随重金属浓度增加而明显下降；土壤脱氢酶、脲酶、酸性磷酸酶活性的下降幅度较为明显，过氧化氢酶、蔗糖酶活性次之，蛋白酶活性较为稳定。 - There were significant negative relationships among soil microbial carbon , microbial nitrogen , basal respiration , microbial metabolic quotient , urease activity , dehydrogenase activity , nitrification , nitrogen fixation and cadmium or lead concentration ( r0 . 01 = 0 . 765 , r0 . 05 = 0 . 632 ) . there was a close positive relationship between soil microbial biomass c : n ratios and cadmium or lead concentration ( r = 0 . 8920 )
上述微生物活性指标与重金属间的相关性分析表明，微生物生物量碳、基础呼吸、微生物代谢商、脱氢酶活性与cd 、 pb的加入量呈极显著负相关性，土壤微生物生物量c n比与cd 、 pb的加入量呈现极显著正相关关系。 - Soil microbial biomass and viable population size ( plant counts ) were negatively affected by the elevated metal levels , but the size of soil basal respiration rate and microbial metabolic quotients were positively influenced by the increasing heavy metal pollution levels . microbial community structure also changed with increasing contamination , as indicated by biolog data and principal component analysis of biolog community metabolic profiles . soil microbial metabolic profiles ( awcd ) values , community richness and diversity index in mine - soils decreased remarkably as compared
相关分析结果表明，土壤重金属含量和土壤基础呼吸、微生物量cfn 、代谢剖面( awcd ) 、微生物商( cmic / corg ) 、代谢商( qc02 )与人工栽培的香根草植物地上部分呈显著或极显著正相关(卜0 . 6653飞0 . 8945 ” ) ;微生物量c 、微生物量n 、生化作用强度、酶活性、群落shannon指数( h )和微生物群落丰富度( s )与人工栽培的香根草植物地上部分生物量呈显著或极显著地负相关( r =一。
