Abstract
The increase of atmospheric CO2 concentration and ultraviolet-B radiation(UV-B)significantly affect crops growth,development and physiological processes.In this study,the soil enzyme activities and amount of soybean rhizosphere ammonia-oxidizing bacteria were analyzed under the condition of doubled CO2 concentration and enhanced UV-B irradiation.Related experiments were imitated in artificial climate room using super-nodulating mutant 0498 and not nodulated soybean mutant 0701 as materials.The results showed that,the amounts of soybean rhizosphere ammonia-oxidizing bacteria activities of soil urease,invertase,acid phosphatase and alkaline phosphatase of doubled CO2were enhanced compared with CK;the influence on 0701 was more significant.UV-B had no effect on amounts of soybean rhizosphere ammonia-oxidizing bacteria and reduced soil enzymes activities.The existence of super nodule could lessen the influence of CO2 concentration and UV-B irradiation on soybean rhizosphere ammonia-oxidizing bacteria and soil enzyme activities.
