Embodiment 1

[0022] A strain of Mortierella alpina ( Mortierella alpina QY), the strains have been preserved in the preservation unit designated by the State Intellectual Property Office, the preservation date is February 28, 2019, the name of the preservation unit: General Microbiology Center of China Committee for the Preservation of Microbial Cultures, and the preservation number is: CGMCC No . 17077, address: No. 3, Yard 1, Beichen West Road, Chaoyang District, Beijing, Institute of Microbiology, Chinese Academy of Sciences. The surface soil nutrient indicators are: pH 5.99, soil organic carbon 16.67 g / kg, total nitrogen 1.77 g / kg, total phosphorus 2.23 g / kg, total potassium 13.17 g / kg, available phosphorus 29.25 mg / kg, available potassium 427.83 mg / kg.

[0023] Mortierella longospora ( Mortierella elongata For the separation method of SX), refer to CN 107760610 A.

Abstract

The invention relates to mortierella alpina and application thereof. The mortierella alpina strain is preserved in a collection unit specified by the National Intellectual Property Administration on February 28th, 2019, the name of the collection unit is the China General Microbiological Culture Collection Center (CGMCC), and the collection number is CGMCC No.17077. The mixed mortierella agent hasa better application effect than a single mortierella alpina or mortierella elongate agent, can directly promote straw degradation and increase quick-acting carbon-nitrogen nutrients of oil and enzyme activity related to carbon, nitrogen and phosphorus, can also secrete auxin, zeatin and abscisic acid, and has the potential of promoting crop growth. The two strains of mortierella are obtained byculturing and separating from fertile farmland soil in which organic fertilizer is applied for a long time, can automatically propagate and grow in the soil environment, and are harmless to the environment, the subculture of the strains and the preparation method of the agent are simple, the cost of raw materials of the agent is low, and the agent can be popularized and applied in the agriculturalfield.

Description

technical field [0001] The invention belongs to the field of microbial bacterial agents, and in particular relates to a Mortierella alpina strain and its application. Background technique [0002] Fungi are an important part of the soil microflora. Soil fungi play key roles in agricultural ecosystems, including degrading organic matter, promoting nutrient cycle transformation, and improving nutrient uptake by crops. Mortierella is a genus of Zygomycota, Zygomycetes, Mucorales, Mortierellaceae, and a class of saprophytic fungi. Certain Mortierella fungi play an important role in promoting the degradation of organic materials, increasing soil nutrient transformation, increasing crop yields, and improving soil health. [0003] Recent studies have shown that the abundance of certain Mortierella species is significantly increased in soils with long-term application of chemical and organic fertilizers (Francioli, D., Schulz, E., Lentendu, G., Wubet, T., Buscot, F. ., Reitz, T...
