| 摘 要： | 利用稀释法和比色法对生物托盘根际和非根际土壤微生物数量和酶活性进行测定。结果表明:土壤微生物和酶在植物根际有着明显的根际效应,各级托盘中微生物在根际的数量均大于相应微生物在非根际的数量;在各级托盘中均存在细菌>放线菌>真菌的数量关系。而对土壤蛋白酶和脲酶活性的研究发现根际酶活性明显高于非根际酶活性。

| Abstract: | Bin-salver is a new wastewater treatment system based on the combined effect of substrate,plant and microbes.The amount of soil microbes and activity of enzyme in rhizosphere and non-rhizosphere of bio-salver were determined by dilution and colorimetry.Results showed that soil microbes and enzyme has represented root domino effect.The surface of root soil was markedly more favorable to microbes and enzyme in every layer of bio-salver,with quantitative of soil microbes in the order of bacteria,actinomycete and epiphyte.The activity of protease and urease in rhizosphere was higher than those in non- rhizosphere. |
