[Purpose] The Nitrification inhibitor plays a significant role in mitigation of climate change, leaching of nitrate nitrogen and improvement of agricultural productivity and quality in greenhouses. Here we show a strong correlation between soil microbes and cucumber root systems according to our observation in greenhouse in north China by application of nitrification inhibitor to cucumber soil. [Methods] The effects of environmental factors and the function of dominant flora were further explored by deep pyrosequencing of 16S rRNA. [Results] It was shown that Proteobacteria, Actinobacteria, Chloroflexi, Germmatimonadates, Acidobacteria and Nitrospirae were the most abundant bacteria among all 783942 bacterial 16S rRNA genes clustering at the 97% similarity level. Furthermore, the Chao1,Shannon and Simpson index of AOA diversity, as well as the ACE and Chao1 index of AOB diversity with In-1 and In-2 treatment was not significantly different with treatments FP. Reducing the use of chemical fertilizers and organic fertilizers by 25% (OPT) significantly reduces the microbial diversity in the soil. In addition,it was found pH and Organic matter play dominant role in community structure among. [Conclusions] The application of nitrification inhibitors for three years did not cause negative effects on the microbial diversity in soil, and it still maintained the richness and evenness of the diversity in greenhouse soil. This work provides deeper understanding for evaluation of managing nitrogen conversion process and its effect on environment in greenhouse soil.
