Heterotrophic nitrification characteristics of five aerobic denitrifiers which belong to different genus were studied .
对五株不同菌属的好氧反硝化菌进行了异养硝化性能研究。
Nitrification inhibition and dose-dependent effect of dicyandiamide on sandy , loamy and clayey soils .
在不同质地土壤上的硝化抑制效果和剂量效应研究。
Terrestrial microorganisms play a vital role in soil nitrogen cycling . They participate in important ecological processes such as nitrogen fixation , ammonification , nitrification and denitrification .
The respiration , ammonification , nitrification and cellulose decomposition of the soil in the drought white gourd forest were all higher than that in other utilization types of soils .
旱冬瓜林地土壤呼吸作用、氨化作用、硝化作用和纤维素分解作用均高于其他利用类型土壤。
Potential nitrification rate of the soil rose sharply during the early rice growth period , peaked at the booting stage and then declined somewhat .
水稻生长前期土壤硝化势也具有显著上升趋势,孕穗期时达到最高,而后有所下降。
N itrification inhibitors are toxic to nitrifying bacteria and temporarily retard the nitrification process .
