EFFECTS OF ELEVATED SURFACE O3 CONCENTRATION ON FUNCTIONAL DIVERSITY OF SOIL MICROBIAL COMMUNITY IN RICE FIELD
摘要
Abstract
Effect of elevated surface O3 concentration (～ 70 nmol mol-1) on functional diversity of soil microbial communities in paddy field under the rice/wheat rotation system was investigated in 2009 and 2010 through determination of water-soluble organic carbon (WSOC) content and BIOLOG index, by making use of the O3-FACE (Free-Air ozone Concentration Enrichment) platform of China. Results show that with O3concentration elevated, both WSOC content, and AWCD (Average Well Colour Development) tended to decrease. Diversity indexes determined in the two years indicate that elevated O3 concentration did not have much effect on, Shannon, Simpson and Mclntosh indices. PCA results in 2010 show that elevation of O3 concentration affected the edaphon' s ability of utilizing substrates of some specific carbon sources. The findings of the experiment suggest that under elevated O3 concentration (～ 70 nmol mol-1) , functional diversity of soil microbes was significantly increased in rice field.关键词
