Preparation method of foliar fertilizer rich in selenium and amino acid

[0029] In a specific embodiment of the present invention, a kind of preparation method of the foliar fertilizer that is rich in selenium and amino acid comprises the following steps:

[0030] 1) Prepare compound probiotic bacteria liquid. The compound probiotics in this step are composed of photosynthetic bacteria, yeast, spores and lactic acid bacteria. The weight percentages of the four kinds of bacteria in the compound probiotic bacteria solution are preferably: 10-25 wt% of photosynthetic bacteria, 15-30 wt% of yeast, 20-30 wt% of spores and 30-40% of lactic acid bacteria. More preferably: 20wt% of photosynthetic bacteria, 20wt% of yeast, 25wt% of spores, and 35wt% of lactic acid bacteria. Photosynthetic bacteria is made up of capsule rhodopseudomonas (Rhodopseudomonas capsulata) and spherical rhodopseudomonas (Rhodopseudomonas sphaeroides), and the weight ratio of two kinds of photosynthetic bacteria is preferably capsular rhodopseudomonas: rhodopseudomonas spherical= 5:2,

[0037] The preparation method of the foliar fertilizer of the present embodiment may further comprise the steps:

[0038] 1) Prepare compound probiotic bacteria liquid. This step mainly includes three sub-steps of preparing single-strain bacterial liquid, compound bacterial liquid, and preparation of compound probiotic bacterial liquid. The specific process is as follows:

[0039]First of all, the inventors prepared Rhodopseudomonas capsulatum, Rhodopseudomonas globosa, Saccharomyces cerevisiae, grape juice yeast, Bacillus subtilis, Bacillus licheniformis, para Lactobacillus casei and Lactobacillus rhamnosus. First activate and expand the preserved strains of Rhodopseudomonas capsulata, Rhodopseudomonas globosa, Saccharomyces cerevisiae, grape juice yeast, Bacillus subtilis, Bacillus licheniformis, Lactobacillus paracasei and Lactobacillus rhamnosus respectively The culture is prepared into a liquid seed solution, which is then inserted into a corresponding liquid fermentation

[0046] The preparation method of the foliar fertilizer of the present embodiment may further comprise the steps:

[0047] 1) Prepare compound probiotic bacteria liquid. First prepare single-strain bacterium liquid and compound bacterium liquid according to the same method as Example 1, then follow the formulation of 20wt% photosynthetic bacteria bacterium liquid, 20wt% saccharomyces bacterium liquid, 25wt% spore bacterium liquid and 35wt% lactic acid bacteria bacterium liquid Composite probiotic bacterial liquid 2 was obtained by mixing four bacterial liquids.

[0048] 2) Prepare the mixed material. Take by weighing 1000kg compound probiotic bacterium liquid 2, 200kg cooked fish paste, 25kg urea, 50kg potassium sulfate, 100kg sugarcane molasses and 1.0kg sodium selenite, then add six kinds of raw materials in the same fermenter, stir evenly to obtain Mixed ingredients.

[0049] 3) Ferment the mixed material obtained in step 2) at a temperature higher than 10° C. for 40 days, s
