根际是植物根系和土壤的交界面,蕴含了丰富的微生物类群,根际微生物对农作物的生长和健康均有影响。研究根际微环境下微生物的空间分布、解析其驱动因子,对阐明农田土壤微生物群落构建过程以及揭示其生态功能具有重要意义。基于此,中国科学院南京土壤研究所褚海燕课题组2015年6月在大尺度下(80万平方公里)采集了华北平原麦田根际土壤样品,利用高通量测序、生物信息分析等技术,研究小麦根际土壤
The rhizosphere is the interface of plant roots and soil, which contains abundant microbe groups. The rhizosphere microbes have effects on the growth and health of crops. Studying the spatial distribution of microorganisms in the rhizosphere micro-environment and analyzing their driving factors are of great significance for elucidating the process of soil microbial community construction and revealing its ecological functions. Based on this, the research team of Chu Haiyan, Nanjing Institute of Soil Science, Chinese Academy of Sciences, collected rhizosphere soil samples from the North China Plain in June 2015 at a large scale (800,000 km2). Using high-throughput sequencing and bioinformatics analysis, Wheat rhizosphere soil
