Embodiment Construction

[0010] 14 inorganic phosphorus-dissolving strains (YCWP1-14) and 16 organophosphorus-dissolving strains (YCYP1-16) were preliminarily screened out by using the selective medium and the difference in colony morphology. Spot the phosphorus-dissolving strains on the phosphorus-containing plate, and observe the size of the colony and the size of the phosphorus-dissolving circle after culturing for 3 days. The experimental results show that only 7 strains have the phosphorus-dissolving ability if the phosphorus-dissolving circle appears. Among them, the phosphorus-dissolving ability of YCYP9 and YCYP15 strong (Table 1).

Abstract

The invention discloses a burkholderia strain and application thereof. The strain is named as Burkholderia sp. YCYP9 in taxonomy, and the preservation number of the strain is CCTCC (China Center For Type Culture Collection) NO: M 2021733. The strain has the function of simultaneously dissolving inorganic phosphorus and organic phosphorus, and can be used for preparing a phosphorus-dissolving preparation. Meanwhile, the strain also has a function of promoting the growth of camellia oleifera seedlings, and can be used for preparing a camellia oleifera seedling growth promoter.

Description

technical field [0001] The invention relates to a Burkholderia strain and its application, in particular to a Burkholderia strain YCYP9 capable of dissolving phosphorus and its application in the growth of Camellia oleifera seedlings. Background technique [0002] Camellia olefera (Camellia olefera) is a general term for oil-using species with high seed oil content and production value in the Theacae (Theacae) genus Camellia. It is a unique high-quality woody oil tree species in my country. Known as the world's four largest woody oil tree species. my country's existing Camellia oleifera cultivation area is 68 million mu, mainly distributed in 14 southern provinces (regions), with a total industrial output value of 116 billion yuan. The camellia oil extracted from Camellia oleifera seeds has a unique flavor, rich nutrition, reasonable fatty acid composition, and high unsaturated fatty acid content. 90%, oleic acid content is more than 80%, does not contain erucic acid and behe...
