Introduction and methods To further explore the biochar–soil–plant interaction mechanisms, rice husk biochar root-promoting solutions were used to prepare extracts compound aqueous solutions, study regulation of acid extract its water agent on growth tobacco, as well effects main nutrient content (nitrogen, phosphorus, potassium), microbial abundance, functional diversity in rhizosphere soil tobacco. Results The results showed that application different concentrations enhanced tobacco plant dry matter accumulation, improved pH, increased available nitrogen organic matter, reduced potassium phosphorus availability. Moreover, effect treatment group nutrients was greater than group. In terms microorganisms, relative abundance Sphingomonas , Vicinamibacteraceae bacterial genus, Mortierella Penicillium fungal bacteria such chemoheterotrophs, aerobic saprotrophs, promoting complexity interconnectivity networks. Discussion summary, improve by enhancing structure, diversity, groups community, thereby growth. These not only provide a theoretical basis for mechanism between biochar, soil, but also certain support development related fertilizers.
