Abstract:
This paper took treated tomato soil samples as experimental material to study changes of soil microbial biomass by using methods of oxygen-enrichment and non-oxygen-enrichment respectively.Oxygen-enrichment mode irrigation of 5‰ hydrogen peroxide to the pot while non-oxygen-enrichment mode irrigation of water after cooling.Different amount of water was irrigated to tomato soil previously processed by using the above methods and soil samples with different water content of 50%-55%，65%-70%，80%-85% respectively were obtained，whose microbial biomass were further measured by employing dilute approach.The results showed that for the tomato soil without increasing oxygen，bacteria and actinomycetes had the maximum of microbial biomass when the soil moisture content reached 50%-55%，while fungi had the maximum of microbial biomass when the soil moisture content reached 80%-85%.For the tomato soil pretreated by oxygen-enrichment method，actinomycetes had the maximum of microbial biomass when the soil moisture content reached 50%-55%.The final results showed that under the condition of different moisture content，the soil without increasing oxygen contained more microbial biomass than that added with oxygen.Moreover，for the soil added with oxygen，the quantity of bacteria and fungi didn’t change too much under different condition of soil moisture content and the quantity of actinomycetes reached the most.
