摘要:

改善水旱轮作土壤结构,可提高冬作马铃薯土壤养分供给效率。以马铃薯‘费乌瑞它’为试验材料,探究短期施加泥炭(PS)和蘑菇渣(MR)的土壤改良方式对稻田土壤物理特性及养分组成的综合影响;利用宏扩增子测序分析手段,明确改土处理对根源微生物组结构和功能的影响。结果表明:泥炭和蘑菇渣处理都在一定程度上改变了各粒级团聚体在土壤中的分布比例;两种处理也都可以显著提高土壤有机质含量,增加速效磷与速效钾含量。另外,改土处理提升了根际微生物群落多样性,其中变形菌门、放线菌门、拟杆菌门及厚壁菌门在根际和根系内生区域为共有优势菌门。主坐标分析(PCoA)结果显示,相较于细菌群落,马铃薯真菌群落构成相对稳定,受改土处理影响较少。共现网络分析结果显示泥炭土处理表现出更紧密的节点连接及更明显的模块化趋势,并在根系内生菌群中表现最为显著。环境因子与微生物关联分析(CCA)结果显示土壤有机碳(TOC)和全氮(TN)可显著影响细菌及真菌群落组成。综合改土处理下马铃薯的产量结果,认为泥炭土处理较适于稻田土壤改良,具有一定应用推广前景。

Abstract:

Improving soil structure of the paddy-upland rotation is an important measure to enhance the efficiency of soil nutrient supply for winter potatoes. In this study,an investigation was undertaken to explore the comprehensive effects of peat soil(PS)and mushroom residue(MR)short-term application on the soil physicochemical properties and nutrient composition of paddy soils,using the potato cultivar ‘Favorita’as the experimental material. High-throughput amplicon sequencing was utilized to clarify the impact of soil improvement treatments on the structure and function of the root-associated microbiome. Results showed that PS and MR treatments have altered the proportionate distribution of soil aggregates to a certain extent;both treatments also significantly increased soil organic matter content,as well as the levels of available phosphorus and potassium. The soil improvement treatments also enhanced the diversity of the rhizosphere microbial community,with Proteobacteria,Actinobacteria,Bacteroidetes,and Firmicutes being the dominant phyla in both rhizosphere and endophytic regions. Principal coordinate analysis(PCoA)results showed that,compared to bacterial communities,fungal community compositions were relatively stable,and less impact on changes induced by soil amendments. Co-occurrence network analysis revealed that PS treatment resulted in tighter node connections and a more prominent network modularity tendency,especially among the endophytic compartment. Canonical Correspondence Analysis (CCA)indicated that soil organic carbon(TOC)and total nitrogen(TN)significantly influenced the composition of both bacterial and fungal communities. Considering the potato yield results under the combined soil improvement treatments,peat soil amendment appears to be more suitable for the amelioration of paddy field soils and has potential for application.
