Abstract

This invention belongs to the field of microbial technology, specifically relating to a compound microbial fertilizer that synergistically regulates rhizosphere flora and nitrogen metabolism genes and its application. The microbial agent includes: Bacillus belye (… Bacillus velezensis ), Bacillus subtilis subsp. subtilis ( Bacillus subtilis subsp. subtilis ) and Linyi Streptomyces ( Streptomyces linyiensis Two or three of the following. The microbial agent provided by this invention has significant growth-promoting and nitrogen-fixing effects when applied to crops. It can maintain or even improve soil fertility and crop yield under the condition of reducing nitrogen fertilizer application by 30%, providing a green and efficient new solution for the implementation of "nitrogen reduction and efficiency enhancement".
