Китайский. 研究了小油菜栽培过程中含碘凹凸棒对土壤微生物的影响.结果表明：凹凸棒中碘酸钾的含量能影响土壤微生物类群总数、放线菌数量和细菌数量,不影响真菌数量;碘酸钾含量≤50 mg.kg-1时能极显著增加土壤中微生物总数、放线菌数量和真菌数量;与对照相比,放线菌、细菌、真菌数量增幅都随改良剂中碘酸钾含量的增加而减少;随着凹凸棒中碘酸钾含量的增加,放线菌和真菌所占比例上升,细菌所占比例下降;土壤微生物多样性指数在不同处理间存在着差异,凹凸棒中碘酸钾含量为100 mg.kg-1时多样性指数最大.[著者文摘]

The effects of attapulgite with iodine on soil microbe during the cultivation of pakchoi were studied.The results showed that the potassium iodate content of attapulgite had the effects on total number of soil microbe groups,actinomycetes and bacteria quantity,but had no effect on fungi quantity.When the potassium iodate content of attapulgite was less than 50 mg・kg-1,the total number of soil microbe groups,actinomycetes and fungi quantity were all extremely increased.Compared with the control,with the increasing of potassium iodate content of attapulgite,the increasing range of actinomycetes,bacteria and fungi quantity reduced,the proportions of actinomycetes and fungi increased while that of bacteria decreased.The biodiversity index of soil microbe were different among different treatments,it reached to the highest when the potassium iodate content was 100 mg・kg-1.[著者文摘]
