  soil basal respiration
Amended soil showed higher values of microbial biomass C, soil basal respiration and dehydrogenase activity than control soil, which reached values near to those of the natural soils in the area.
      
Soil basal respiration, microbial biomass C and anaerobically mineralisable N were significantly increased in the amended plots.
      
Soil basal respiration (Rmic), the metabolic quotient for CO2 (qCO2=Rmic/Cmic), microbial C and N (Cmic and Nmic) as well as total soil organic C and N showed no response to CO2 enrichment alone.
      


Soil basal respiration potential, metabolic quotient (qCO 2), and activities of urease, invertase and acid phosphomonoesterase were investigated in the root layer of 10 , 40 , and 90 yr old tea bushes grown on the same type of red soil. The soil daily basal respiration potential ranged from 36.23 to 58.52 mg·kg -1 ·d -1 , and the potentials in the root layer of 40 or 90 yr old were greater than that of 10 yr old tea bushes.The daily qCO 2, ranging from 0.30 to 0.68, was in the reverse trend....

Soil basal respiration potential, metabolic quotient (qCO 2), and activities of urease, invertase and acid phosphomonoesterase were investigated in the root layer of 10 , 40 , and 90 yr old tea bushes grown on the same type of red soil. The soil daily basal respiration potential ranged from 36.23 to 58.52 mg·kg -1 ·d -1 , and the potentials in the root layer of 40 or 90 yr old were greater than that of 10 yr old tea bushes.The daily qCO 2, ranging from 0.30 to 0.68, was in the reverse trend. The activities of test three enzymes changed differently with tea bushes' age. Urease activity in the root layer of all age tea bushes ranged from 41.48 to 47.72 mg·kg -1 ·h -1 and slightly decreased with tea bushes' age. Invertase activity was 189.29~363.40 mg·kg -1 ·h -1 and decreased with tea bushes' age, but its activity in the root layer of 10 year old tea bushes was significantly greater than that in the root layer soil of 40 or 90 year old tea bushes. Acid phosphomonoesterase activity (444.22~828.32 mg·kg -1 ·h -1 ) increased significantly with tea bushes' age. Soil basal respiration potential, qCO 2 and activities of 3 soil enzymes were closely related to soil pH, soil organic carbon, total nitrogen and C/N ratio, total soluble phenol, and microbial biomass carbon, respectively.

对不同树龄茶树根层土壤的呼吸作用 (包括代谢熵 qCO2 )和土壤酶 (脲酶、转化酶和酸性磷酸单酯酶 )活性进行了研究 .不同树龄茶树根层土壤日基础呼吸作用强度 (3 6.2 3~ 5 8.5 2mg·kg-1·d-1)和日代谢熵 (0 .3 0~ 0 .68)都以 40和 90年茶树较为接近 ,分别显著大于和小于 10年树龄茶树根层土壤 ;脲酶活性 (41.48~ 47.72mg·kg-1·h-1)则三者间差异不大 ,虽然随树龄增长而下降 ;转化酶活性 (189.2 9~3 63 .40mg·kg-1·h-1)也随树龄增长而下降 ,并且 10年茶树根层土壤显著大于 40和 90年树龄茶树 ;而酸性磷酸单酯酶活性 (44 4.2 2~ 82 8.3 2mg·kg-1·h-1)相反 ,随树龄增长而增强 .结果表明 ,土壤基础呼吸作用、代谢熵和 3种土壤酶活性都与茶树树龄、土壤 pH、土壤有机碳、土壤全氮、土壤可溶性酚总量、及土壤微生物生物量密切相关

Soil basal respiration,soil biomass carbon,metabolic quotient are important indexes of soil microbiological,they relate to physical-chemical character of soil.The dehydrogenase activity is the important sensitivity index of microbial community and activity on soil.Different added lead concentration ranging from 200 mg/kg to 1 200 mg/kg effect on soil basal respiration,soil biomass carbon,metabolic quotient and dehydrogenase activity.The experiment was studied in house incubated soil samples.The results showed as follows: soil biomass carbon decrease with extend incubated times.Soil basal respiration was increased with increased concentration of lead.Soil metabolic quotient were changed with different incubated time.Soil dehydrogenase significantly decrease under lead stress.The correlation analysis indicated that soil added lead content different correlation with soil biomass carbon,dehydrogenase activity in different incubation times.

土壤微生物量碳、基础呼吸作用、土壤代谢商是表征土壤质量的重要指标,并且与土壤本身的理化性质有关。脱氢酶活性是土壤微生物种群及其活性的重要敏感性指标之一。通过室内培养,研究了不同铅添加水平(200~1 200 mg/kg)对青紫泥田微生物生物量碳及土壤基础呼吸作用、土壤代谢商、土壤脱氢酶的影响。研究表明:随培养时间延长,青紫泥田生物量碳呈下降趋势,基础呼吸作用随铅浓度升高而加强。土壤代谢商随培养时间延长变化趋势不同。外源铅胁迫下土壤脱氢酶活性随铅处理浓度升高明显受抑制。相关分析表明,土壤铅含量与土壤微生物生物量碳、脱氢酶在不同培养时期相关性不同。
