摘　　要：为明确魔芋等作物生长过程中的细菌种类、微生物多样性的分布特点,更好地研究作物生长过程中有益细菌与气象因子共同发挥作用,有效促进作物的生长或抑制植物病害的发生,采集四川省美姑县主要种植基地的魔芋、花椒和玉米套作地的土壤作为样本,选择具有代表性的10块种植地土壤样本作为研究对象,进行分离鉴定。研究不同的气象因素和根系微生物的协同作用,通过拟合曲线证明,魔芋套作生长发育过程中,根系微生物的丰度分布有明显的时间节律,表现出规律性的变化。利用微生物的抗干旱、解磷、增强植物抵御病原菌等特性,为发现适宜的风速、土壤温度和土壤湿度可以调控根系中的微生物群落提供理论依据。To clarify the distribution characteristics of bacterial species and microbial diversity during the growth process of konjac and other crops,and to better study the process of crop growth in which these beneficial bacteria and meteorological factors can play a role together to effectively promote the growth of crops or inhibit the occurrence of plant diseases.Soil from konjac,pepper,and corn set crops in the main planting bases of Meigu County,Sichuan Province was collected as samples,and soil samples from 10 representative planting sites were selected as investigation and research objects for isolation and identification.The synergistic effects of different meteorological factors and root microorganisms were investigated,and it was proved by fitting curves that the abundance distribution of root microorganisms in the growth and development process of konjac intercropping had an obvious time rhythm and showed regular changes.Utilizing a series of properties of microorganisms,such as anti-drought,phosphorus solubilization,and enhancement of plant resistance to pathogenic bacteria,we provide a theoretical basis for the discovery that suitable wind speed,soil temperature and soil moisture can regulate the microbial community in the root system.
