Microcosm experiments were carried out to study the effects of bacterial-feeding nematodes and indigenous microbes and their interactions on the degradation of prometryne and soil microbial activity in contaminated soil. The results showed that soil indigenous microbes could degrade prometryne up to 59.6-67.9%; bacterial-feeding nematodes accelerated the degradation of prometryne in contaminated soil, and prometryne degradation was raised by 8.36-10.69%. Soil microbial biomass C (C(mic)), basal soil respiration (BSR), and respiratory quotient (qCO(2)) increased in the beginning of the experiment and decreased in the later stage of the experiment. Nematodes grew and reproduced quite fast, and did increase the growth of soil microbes and enhance soil microbial activity in prometryne contaminated soil during the incubation period.
开展微宇宙实验，研究食细菌线虫和土著微生物及其相互作用对污染土壤中甲草胺降解和土壤微生物活性的影响。结果表明，土壤土著微生物可降解甲草胺达 59.6-67.9%；食细菌线虫加速了污染土壤中甲草胺的降解，使甲草胺降解率提高了 8.36-10.69%。土壤微生物生物量碳（C（mic））、基础土壤呼吸（BSR）和呼吸商（qCO（2））在实验初期增加，在实验后期减少。线虫生长繁殖迅速，在培养期间增加了土壤微生物的生长，增强了污染土壤中甲草胺的土壤微生物活性。
