Title:
ENHANCED HIGH-EFFICIENCY NITROGEN-FIXING COMPOUND BACTERIAL SYSTEM HAVING NON-NITROGEN-FIXING BACTERIA ADDED THERETO AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/242570
Kind Code:
A1
Abstract:
Provided are a nitrogen-fixing compound bacterial system comprising nitrogen-fixing bacteria and non-nitrogen-fixing bacteria, and an application thereof, the nitrogen-fixing bacteria comprising Klebsiella MNAZ1050, Citrobacter MNAZ1397 and Pseudomonas MNAZ228, and the non-nitrogen-fixing bacteria comprising Acinetobacter ACZLY512 and Klüvorella AZ981. The nitrogen-fixing bacteria in the nitrogen-fixing compound bacterial system have a relatively good nitrogen-fixing effect when used alone, while the cooperative use of the nitrogen-fixing bacteria and the non-nitrogen-fixing bacteria to construct a nitrogen-fixing compound bacterial system has a more significant nitrogen-fixing effect than when the nitrogen-fixing bacteria are used alone, which can promote crop growth under conditions in which nitrogen application is significantly reduced.
