Abstract

The invention discloses a composite microbial agent, and a preparation method and an application thereof, and belongs to the technical field of preparation of fertilizers. The composite microbial agent comprises, by weight, 18-30 parts of Bacillus licheniformis, 14-20 parts of nitrifying bacteria, 9-13 parts of yeast, 7-12 parts of Azotobacter chroococcum, 5-10 parts of phosphobacteria and 4-6 parts of potassium bacteria. The composite microbial agent is prepared through the steps of activation, expansion culture and centrifugation de-watering. The composite microbial agent is used for preparing a selenium-enriched ecological bacterial fertilizer for crops, and the ecological bacterial fertilizer can increase the yield and the selenium content of pakchoi.

Description

【Technical field】 [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a composite microbial agent, a preparation method and an application thereof. 【Background technique】 [0002] Selenium is an essential trace element for the human body, an antioxidant to maintain the balance of the body, and is known as the trace element that dominates life. Selenium can enhance the body's immunity, prevent diabetes, cataract and cardiovascular and cerebrovascular diseases, and also has the functions of detoxification, detoxification, prevention of liver disease and protection of the liver. When planting crops with high selenium content, it is necessary to invest in fertilizers with high selenium content to increase the enrichment of selenium in plants, so that selenium can be absorbed by the human body. [0003] The Chinese patent application document "A Selenium-enriched Liquid Bacterial Fertilizer and Its Preparation Method and Ap...
