The invention discloses a composite
microbial inoculant for soil improvement, which is prepared from the following raw materials:
Providencia retinii S17-1,
Serratia sp. VL03-3,
Pantoea eucallypti P2FPb1 (
Pantoea eucallypti P2FPb1) and Bacillus proteolyticus 1372 (Bacillus proteolyticus 1372), and the composite
microbial inoculant is prepared from the following raw materials:
Pantoea eucallypti P2FPb1, Pantoea eucallypti P2FPb1, Pantoea eucallypti P2FPb1, Pantoea eucallypti P2FPb2, Pantoea eucallypti, Pantoea eucallypti, Pantoea eucallypti On the other hand, the invention discloses a preparation method of the compound
microbial inoculant. The preparation method comprises the following steps: acquiring a single colony, preparing a
single strain solution, mixing the
single strain solution, and inoculating and culturing. The composite microbial inoculant has the composite
growth promoting capacities of dissolving
phosphorus, dissolving
potassium, secreting
plant hormones and the like, does not cause
plant diseases, has good ecological adaptability, is safe to use and high in economic benefit, and does not threaten the
ecological environment. The compound microbial inoculant disclosed by the invention can be used for increasing the
plant yield, improving the
soil enzyme activity and improving the
soil quality and the
rhizosphere micro-
ecological environment.
