Embodiment 1

[0034] 1) Inoculate nitrogen-fixing, phosphorus-dissolving, potassium-dissolving, insect-resistant, disease-resistant, and growth-stimulating strains on the inclined surface of the test tube respectively. Place the slant of the test tube at a constant temperature of 25-32°C for 24-72h.

[0035] 2) Pour the slant of the cultured test tube into sterile water, and scrape the bacterial lawn to prepare a bacterial suspension in a sterile bottle.

[0036] 3) Prepare liquid culture medium, its components are: soybean hydrolyzate 10-30g peptone 4-10g sucrose 16-24g KH 2 PO 4 3~8g MgSO 4 1~6g inorganic selenium 10-100PPM water 1L.

[0037] 4) Steam sterilization, 0.12-0.15Mpa, 121-125°C, 30 minutes.

[0038] 5) Put the strain suspension into the sterilized culture medium.

[0039] 6) Culture at 25-37°C for 36-72 hours.

[0040] 7) Mix the culture fluids obtained from the separate cultures and stir evenly. For the compound ① liquid.

[0041] 8) Activate the strains used for deep...

Abstract

The invention relates to a preparation method of a biological selenium-rich fertilizer. According to the invention, various microbes with specific functions are respectively cultured or are combined and cultured, such that a large amount of selenium-rich living cells are obtained; at a same time, a combined culturing product of various probiotics is fermented under an anaerobic condition, such that a large amount of selenium-rich multi-strain fermentation product is obtained; the products are blended according to a certain ratio, such that the fertilizer is obtained. The fertilizer is characterized in multiple microbe floras, multiple functions, multiple metabolites, stable selenium element content, and substantial application effect. Through foliar fertilization, selenium nutrient contents in various crops can be increased, and agricultural product qualities can be improved. The fertilizer is suitable for spray applications on crops such as melons, leafy vegetables, tobaccos, teas, fruit trees, grains, beans, and the like.

Description

technical field [0001] The invention specifically relates to a preparation method of a biological selenium-enriched fertilizer, which belongs to the technical field of fertilizer production, and is a method for preparing a biological selenium-enriched fertilizer by combining various functional microorganisms and probiotic microorganisms with inorganic selenium elements. Background technique [0002] China is one of the countries with the most serious selenium deficiency in the world, with 72% of the land area in the severe selenium deficiency zone. Including Northeast, North China, Southwest and other major grain areas. As a result, 95% of the selenium content of the grains, fruits and vegetables we eat now cannot meet the international minimum standard. Selenium is a trace element that the human body must obtain from food. Selenium deficiency in food is directly related to personal health. According to the statistics of the International Health Organization, one of the co...
