        Effects of biochar and Trichoderma on bacterial community diversity in continuous cropping soil

        Xia Cao,Ning Zhang,Xiaoyu Zeng,Qinglin Lan,Nan Ma,Chuncheng Wu 한국원예학회 2022 Horticulture, Environment, and Biotechnology Vol.63 No.1

        Soil acidifi cation has become a serious issue in protected production in northern China as a consequence of many years ofcontinuous cropping. Besides aff ecting the growth and quality of vegetables, soil acidifi cation also restricts the sustainabledevelopment of vegetables grown in protected environments. A single application of biochar or Trichoderma can repair thesoil environment, optimize the microbial community structure, reduce plant diseases, and promote plant growth. However,it is not known whether biochar combined with Trichoderma has a synergistic eff ect on these parameters. In this study,long-term continuous cropping of cucumbers in a greenhouse was used to study the eff ect of biochar and Trichoderma onmicro-ecological environmental changes in acidifi ed soil using Illumina sequencing. The results showed that the combinedapplication of biochar and Trichoderma promoted cucumber growth; signifi cantly enhanced root vitality and superoxidedismutase, peroxidase, and catalase activities in leaves; and reduced malondialdehyde content. In addition, soil physicaland chemical properties improved; cation exchange capacity, the activity of soil polyphenol oxidase and invertase, and thediversity of soil bacterial communities increased; and the structure and relative abundance of soil bacteria changed after thecombined application of biochar and Trichoderma . Correlation analysis of environmental factors showed that total nitrogenand soil pH had the greatest impact on bacterial communities. The metabolic function of soil bacteria was improved, andthe circulation of soil nutrients was increased as a consequence of the combined application of biochar and Trichoderma .
