Phosphorus-solubilizing bacterium, phosphorus-solubilizing bacterium agent and biological bacterial fertilizer, and application thereof

Abstract

The invention discloses a phosphate-solubilizing bacterium, a phosphate-solubilizing bacterium agent and a biological bacterial fertilizer, and application thereof. A phosphate-solubilizing bacteriumstrain XQP53 is Burkholderia with an accession number of CCTCC M: 2020254. The phosphate-solubilizing bacterium XQP53 can improve the ground diameter, the plant height and the chlorophyll content of corn, enhance soil nutrients, increase the contents of neutral phosphatase, water-soluble phosphorus and sodium bicarbonate inorganic phosphorus in soil, reduce the content of residual phosphorus in soil, and promote the conversion of active-state and low-activity-state phosphorus in soil into active-state phosphorus. The phosphorus-solubilizing bacterium agent XQP53 has the effects of promoting corn growth, improving soil nutrients and converting phosphorus, and has application value in plant production.

Description

technical field [0001] The invention belongs to the field of microbes, and relates to a phosphate-dissolving bacterium, a phosphate-dissolving bacterium agent and its application. Background technique [0002] Phosphorus, as an important mineral nutrient element in soil, participates in the whole life cycle of plants and plays an important role in the ecosystem. The content of phosphorus in nature is very high, accounting for about 0.28% of the earth's crust. Generally, there is no shortage of phosphorus in the soil, but the soil lacks phosphorus that can be used by plants. Usually, 95% of the soil is ineffective phosphorus. In the hilly areas of southern my country, the soil types are mainly red soil and yellow-brown soil. The soil contains high iron and aluminum ions, which have a strong covalent adsorption effect on phosphorus, which can reduce the bioavailability of phosphorus in the soil. making it difficult for plants to absorb. In addition, as the chemical fertilizer...
