Example Embodiment
[0067] Example 1
[0068] see figure 1 , prepare the high-efficiency fertilizer of the present embodiment according to the following method:
[0069] 1. Accurately weigh 600kg of fulvic acid, 100kg of distiller's grains, 100kg of corn straw powder, 100kg of urea, 20kg of diammonium hydrogen phosphate, 80kg of potassium chloride, and 200kg of yellow water, and mix them evenly to make a fermentation substrate. The moisture content of the fermentation substrate is 25 %.
[0070] 2. After the fermentation substrate is mixed, it is subjected to 0.4 MPa saturated steam through a twin-screw extrusion extruder at 150° C. for extrusion and expansion.
[0071] 3. After the fermentation substrate is puffed, it is transported to the wet material mixer, and then yellow water is added in proportion to continuous stirring and compressed air is introduced to reduce the temperature of the fermentation substrate to 35°C.
[0115] 7. The high-efficiency fertilizer prepared according to the above method has a moisture content of ≤30.00%, a humic acid content of ≥50.00%, a biochemical humic acid content of ≥12.10%, and N+P 2 o 5 +K content ≥ 12.00%, total number of beneficial microorganisms (CFU / g) ≥ 1.50×10 10 , Miscellaneous bacteria rate ≤ 10.00%, total organic acid ≥ 10.00g / kg. Example 2
[0116] see figure 1 , prepare the high-efficiency fertilizer of the present embodiment according to the following method:
[0117] 1. Accurately weigh 500kg of fulvic acid, 200kg of distiller's grains, 185kg of corn straw powder, 50kg of urea, 15kg of diammonium hydrogen phosphate, 50kg of potassium chloride, and 150kg of yellow water, and mix them evenly to make a fermentation substrate. The moisture content of the fermentation substrate is 25 %.
[0118] 2. After the fermentation substrate is mixed, it is subjected to 0.4 MPa saturated steam through a twin-screw extrusion extruder at 150° C. for ext...

Abstract
The invention discloses a mobile fermentation method for producing a concentrated fertilizer through humic acid. The mobile fermentation method comprises the following steps in sequence: adding a base fermentation substance in a dried material mixer and mixing; puffing the mixed material through a twin-screw extruding and puffing machine; conveying the puffed material to a wet material mixer; adding yellow water to cool to 30-35 DEG C; inoculating a mixed bacteria liquid, and fully mixing; filling the mixture into a ventilating film fermenting bag, then packing and sealing; and fermenting for 5 to 10 days in a fermentation chamber at constant temperature, thus obtaining the concentrated fertilizer, wherein the base fermentation substance is prepared by uniformly mixing 50 to 60 parts by weight of fulvic acid, 10 to 20 parts by weight of vinasse, 10 to 20 parts by weight of powdered maize straw, 5 to 10 by weight parts of urea, 1 to 2 parts by weight of diammonium hydrogen phosphate, and 5 to 10 parts by weight of potassium chloride; in the base fermentation substance, the moisture content is 20 to 30wt%, and 10 to 20 parts of yellow water by weight is added; and the mixed bacteria liquid comprises the bacteria liquid of trichoderma harzianum, wet fiber monospora, bacillus latersprorus, bacillus megatherium, azotobacter chroococcum, bacillus mucilaginosus and lactobacillus plantarum.
Description
technical field [0001] The invention relates to a method for producing high-efficiency fertilizers by using humic acid and mobile fermentation, and belongs to the technical field of microbial organic fertilizers. Background technique [0002] China is a large agricultural country, and agriculture is the foundation of the national economy. The development of agriculture is not only of strategic significance to the economic development of our country, but also to the agricultural production and economic development of the world. After China's accession to WTO, food safety and food nutrition are not only the focus of the world's attention, but also the key to whether my country's agricultural products can go to the world and whether they can integrate into the torrent of world trade. At present, traditional chemical fertilizers have been used in large quantities for a long time in agricultural production. Although the output of agricultural products has been greatly improved, i...
