Abstract

A strain of Mortierella alpina and its application. The Mortierella alpina strain has been preserved in a depository designated by the State Intellectual Property Office. The deposit date is February 28, 2019. The name of the depository: China Microorganism Culture Preservation Management Committee Ordinary Microbiology Center, deposit number: CGMCC No.17077. The mixed Mortierella agent has a better application effect than a single Mortierella alpina or Mortierella longospore agent, including being able to directly promote straw degradation, increase soil available carbon and nitrogen nutrients and enzyme activities related to carbon, nitrogen, and phosphorus, and also Secretes auxin, zeatin and abscisic acid, has the potential to promote crop growth. These two strains of Mortierella were isolated from fertile farmland soil with long-term application of organic fertilizers. They can reproduce and grow on their own in the soil environment, and are harmless to the environment. The raw material cost of the agent is low, and it can be popularized and applied in the agricultural field.

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.,...
