摘  要：
[目的]研究东乡普通野生稻(Oryza rufipogon Griff.)根际微生物群落特征。[方法]采用氯仿熏蒸浸提法测定根系微生物生物量碳、氮;采用平板稀释培养法测定群落组成;采用最大或然计数法测定微生物生理群。[结果]东乡野生稻根际微生物生物量碳、氮平均值分别为83.02和16.98mg/kg(土),较普通栽培稻低;根际可培养微生物中细菌>放线菌>真菌;氮素生理群中氨化细菌>好氧固氮菌>反硝化细菌>嫌气性固氮菌>硝化细菌>亚硝化细菌。[结论]东乡野生稻根际微生物群落组成与普通栽培稻相比有差异。

摘  要：
[Objective] The aim was to study the characteristics of microbial community in the rhizosphere soil of Dongxiang wild rice (Oryza rufipogon Griff.). [Method] The microbial biomass carbon and nitrogen was estimated by the chloroform fumigation extraction method; the microbial community composition and nitrogen cycling microbial functional groups were investigated by the dilution plate culture method and the most probable number methods respectively. [Result] The microbial biomass carbon and nitrogen, in rhizosphere soil of Dongxiang wild rice was 83.02 and 16.98 mg/kg(soil), which was lower than that of ordinary cultivated rice; The relationship between the number of culturable microbial groups was bacteria > actinomycetes > fungi, and the nitrogen cycling microbial physiological groups was as the following: ammonifying bacteria > aerobic azotobacteria > denitrobacteria > anaerobic azotobacteria > nitrobacteria > nitrosobacteria. [Conclusion] The microbial community in the rhizosphere soil of Dongxiang wild rice was different from that of the ordinary cultivated rice.
