CO2倍增和UV-B辐射增强对大豆根际氨氧化细菌数量及土壤酶活的影响
Effects of Doubled CO2 and Enhanced UV-B Radiation on Rhizosphere Ammonia-oxidizing Bacteria and Soil Enzymes in Soybean( Glycine max Merr.)
摘要
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 C02 concentration and enhanced UV-B irradiation. Related ex periments 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 C02were 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 en zymes activities. The existence of super nodule could lessen the influence of CO2 concentration and UV-B irradiation on soy bean rhizosphere ammonia-oxidizing bacteria and soil enzyme activities.关键词
