Abstract

Abstract:

【Objective】The objective of the experiment was to determine the effects of different straw biochars on bacterial community structures and composition in yellow soil, and to find main environmental factors as the changes in order to provide information for soil amelioration and proper management of straw residue.【Method】Through a laboratory incubation experiment and used a zonal yellow soil of Guizhou province, the influences of corn, rice and rape straw biochar that were pyrolyzed at 500℃ on bacterial communities were investigated by a high-throughput sequencing (Illumina Hiseq). Correlation and factor analysis of the bacterial community structure with environmental factors were followed. The experiment consisted of four treatments: control soil (CK), soil amended with 500℃ corn (BC1), rice (BC2) and rape (BC3) straw biochar. 【Result】The results showed that the gene copy numbers of bacterial 16S rRNA were closely related with soil total nitrogen (TN), pH and total carbon (TC) (r=0.78**, 0.62* and 0.66*, respectively). Biochar addition to soil increased the richness and diversity of dominant bacteria at phylum and class level, which were a strong positive with pH and C/N. The analysis of bacterial community at phylum level showed that Actinobacteria, Cyanobacteria and Chloroflexi were dominant bacteria, occupying 68.5% of all phyla. Factor analysis showed that soil total nitrogen (TN), C/N ratio, pH, available phosphorus (AP) and cation exchange capacity (CEC) were main environmental factors on the soil bacterial community structure, total explaining 80.8% of the community changes. The order of contribution rate was soil C/N>pH>AP>TN>CEC.【Conclusion】This study provided clear evidence that community composition and chemical properties of bacterial were changed due to biochar addition to yellow soil. And soil TN, C/N, pH, AP and CEC had a greater contribution than environmental factors on the change of the bacterial community structure, in addition, TN and pH were more efficient on improving soil richness and diversity of bacterial community.
