Abstract
This invention provides a compound microbial agent, its preparation method, and its application in promoting the growth of Codonopsis pilosula seedlings, belonging to the field of plant rhizosphere growth-promoting bacteria technology. The halophilic Bacillus HQ-PZ-P16, Arthrobacter spheroides HQ-CZ-L16, and Pseudomonas rhizophilus HQ-CZ-L21 of this invention possess nitrogen-fixing, potassium-forming, phosphorus-solubilizing, IAA-producing, siderophore-synthesizing, and cellulose-decomposing properties. Pot experiments showed that the compound growth-promoting microbial agent prepared from these three bacteria effectively promotes the growth of Codonopsis pilosula seedlings, specifically by significantly increasing root length, root diameter, and root fresh weight, as well as significantly increasing the number of lateral roots and hairy roots. The compound growth-promoting microbial agent provided by this invention is suitable for promoting the growth of Codonopsis pilosula seedlings, and its preparation method is simple, possessing the potential for mass production and application.
