- Abstract:
- In order to find the effect of the soil microbial features under vegetation-growing concrete gunning,the soil microbial biomass and nutrient level of several vegetative restoration patterns including Cynodon dactylon,Festuca arundinacea Medicago sativa were measured.The results showed as the follows: soil organic matter,total nitrogen,available nitrogen and microbial biomass increase after vegetation restoration.Varrious types of vegetation restoration are different in improving soil properties.Generally,the soil organic matter contents and microbial biomass carbon under the different vegetative restoration patterns from followed the order of Festuca arundinacea>Cynodon dactylon>Medicago sativa,but the total nitrogen,available nitrogen,and microbial biomass nitrogen under the different vegetative restoration patterns followed the order of Medicago sativa>Festuca arundinacea>Cynodon dactylon. After vegetation-growing concrete gunning,the intensity of soil respiration increased,while metabolic quotient decreased.The signorificant relationships observed were between SMBC,SMBN,the intensity of soil respiration and physiochemical properties of soil.It is shown that microbial biomass can be used as an indicator of substrate quality.
