Preparation method for burkholderia cepacia, and application in high-performance phosphate-dissolving microbial fertilizer by using the same

The invention relates to a preparation method for burkholderia cepacia, and an application in high-performance phosphate-dissolving microbial fertilizer by using the same. The method is characterized in that: the method comprises the following steps: (1) collecting deficient phosphorus soil for planting corns, putting the soil in a plastic bag, and placing the plastic bag in a 4 DEG C refrigerator for storing; (2) separating and screening a (burkholderia cepacia) strain; (3) detecting phosphorus solubilizing capability of the (burkholderia cepacia) strain; (4) identifying the strain: wherein the screened strain is subjected to a DNA sequencing and a 16SrRNA phylogenetic tree construction to be identified as the burkholderia cepacia. According the present invention, activation rate of the insoluble phosphate in the soil can reach to 10.94%-13.03%, utilization rate of the P reaches to 21.75%-37.98%, and the phosphorus fertilizer amount can be reduced by one third in application for the corns. The phosphate-diss
