Penicillium phosphorus-solubilizing agent as well as preparation method and application thereof

The invention provides a penicillium phosphorus-solubilizing agent as well as a preparation method and application thereof. The penicillium phosphorus-solubilizing agent is a mycelium concentrated product obtained by collecting precipitates after culture, fermentation and filtration of penicillium chinensis TYPS-1 with the collection number of CGMCC No.17668, the phosphorus solubilizing capacity is high, indissoluble phosphorus elements around crop root systems can be decomposed, and the penicillium phosphorus-solubilizing agent is used as a phosphorus-solubilizing preparation for degrading indissolvable inorganic phosphorus of soil. Bran, chaff and other agricultural waste can be used as raw materials to prepare a culture medium for culture to obtain a large quantity of thalli, so that the production cost is reduced, and the production process is simple and suitable for promotion on a large scale. 本发明提供了一种青霉菌解磷剂及其制备方法和应用。所述青霉菌解磷剂通过本发明保藏号为CGMCC No.17668的吉农青霉菌(Penicillium chinensis)TYPS-1经培养、发酵、过滤之后收集沉淀物获得的菌丝浓
