摘要
基于大田试验和扩增子测序技术,分析在常规施肥(CK)基础上添加复合菌剂A(T1)、复合菌剂B(T2)、秸秆(T3)、秸秆+复合菌剂A(T4)和秸秆+复合菌剂B(T5)的处理对云南红壤坡耕地烟田综合应用效应的影响。结果表明,与CK处理相比,单施复合菌剂、秸秆还田及秸秆配施复合菌剂均能不同程度地提高红壤坡耕地土壤细菌群落丰富度、多样性和碱解氮、速效磷、速效钾含量、阳离子交换量及种植效益,改善上部烟叶化学成分的协调性和感官品质,整体以T5处理的综合应用效应较佳。综上,秸秆配施复合菌剂综合应用效应优于单施复合菌剂或单独秸秆还田,秸秆配施复合菌剂B更适合云南红壤坡耕地烤烟栽培。
The comprehensive application effects of conventional fertilization(CK)and adding compound bacteria agent A(T1),compound bacteria agent B(T2),straw(T3),straw+compound bacteria agent A(T4)and straw+compound bacteria agent B(T5)on red soil slope cropland in Yunnan were analyzed using field experiment and high-throughput sequencing technology.The results showed that,compared with CK treatment,single application of compound bacteria agent,straw returning and straw+compound bacteria agent could increase the richness and diversity of soil bacterial community,the contents of alkali-hydrolyzable N,available P and available K,cation exchange capacity,planting benefit,and improved the coordination of chemical components and sensory quality of upper tobacco leaves.The effects of the T5 treatment was better.In conclusion,the comprehensive effects of application straw+compound bacteria agent were better than that of single compound bacteria agent or straw,and had synergistic effects,indicating that straw+compound bacteria agent B model was more suitable for flue-cured tobacco cultivation in red soil sloping farmland in Yunnan.
