Phosphorus-solubilizing bacterial agent as well as preparation and application thereof

The invention provides a phosphate solubilizing bacterial agent as well as preparation and application thereof. The phosphate-solubilizing bacterial agent is composed of penicillium spore powder and aspergillus niger spore powder which are obtained by culturing through a specific method (especially by using a solid propagation medium with specific components and dosage), the two strains play a synergistic effect in the aspects of dissolving a soil indissolvable phosphorus source and the like, and the utilization rate of phosphorus in soil is remarkably increased; the problems of resource waste, environmental pollution and the like caused by excessive use of phosphate fertilizer are relieved, plant growth is effectively promoted, and the method is suitable for preparing bacterial fertilizer. 本发明提供了一种解磷菌剂及其制备和应用。该解磷菌剂由经过特定方法(尤其是使用特定成分及其用量的固体扩繁培养基)培养得到的青霉菌孢子粉末与黑曲霉菌孢子粉末组成，这两个菌株在溶解土壤难溶磷源等方面发挥了协同增效的作用，显著提升了土壤中磷素的利用率，缓解了过量磷肥使用带来的资源浪费和环境污染等问题，有效促进了植物生长，适用于制备菌肥。
