Abstract

The invention relates to a preparation method of an elemental selenium-enriched preparation. The preparation method comprises the following steps: mixing sodium selenite, glucose, starch, protein, calcium carbonate, table salt, amino acids, potassium nitrate, ferrous sulphate, biochemical enzymes and chitosan with deionized water, then inoculating probiotics and fermenting at 25-35 DEG C for 20-40 days under an anaerobic condition to obtain the elemental selenium-enriched preparation, wherein the elemental selenium-enriched preparation contains 0.3-0.4g/L of elemental selenium, the elemental selenium is nanoscale, the average particle size is 60-150nm, and the total number of active bacteria is not less than 10 billions/mL; the probiotics are selected from one or the combination of more of saccharomycetes, lactic acid bacteria, bacillus and actinomycetes; the elemental selenium-enriched preparation contains nitrogen, phosphorus, potassium and trace elements necessary to plants except for selenium element, and has a production-increasing effect on grape; the selenium-enriched preparation has a stress-resistant effect on crop diseases and pests, has an antagonistic effect on harmful heavy metals, has a degradation effect on nitrate in vegetables, and can be used for reducing the application amounts of pesticides.

Description

technical field [0001] The invention relates to a preparation method of an elemental selenium-enriched preparation, belonging to the technical field of agricultural planting. Background technique [0002] my country is a big selenium-deficient country. The census proves that more than 70% of the soil in our country is seriously deficient in selenium, and the selenium content in more than 95% of the grain and livestock and poultry meat in our country is less than 50 μg / kg, which belongs to a large selenium-deficient country. The per capita selenium intake in my country is only about 39 micrograms per day, which is less than 80% of the minimum requirement for adult success of 50 micrograms per day, and is far from the healthy requirement of 100-200 micrograms per day; it is farther away from the safe upper limit of 800 micrograms. In my country, except for a few areas, 90% of the population needs to use bioengineering technology to supplement selenium. Not only people need t...
