Description

technical field

[0001] The invention belongs to the field of phosphorus-dissolving microbial fertilizers. Specifically, the present invention relates to a high-efficiency phosphorus-solubilizing fungus Aspergillus niger and its application, and a phosphorus-dissolving microbial bacterial agent prepared by using the Aspergillus niger. Background technique

[0002] Phosphorus is one of the three major nutritional elements necessary for plant growth and development. Phosphorus is not only the basic constituent element of many organic compounds such as genetic material DNA and energy material ATP in plant cells, but also the photosynthesis of plants and the biochemical metabolism process in the body. Phosphorus plays an irreplaceable role in the whole life process of plants. Phosphorus is not only an important material guarantee for agricultural production, but also a non-renewable mineral resource. In my country, 74% of the arable land is deficient in phosphorus, and the seas...
