Problems solved by technology

Not only the degradation efficiency is not high, but also special strains with high chromium resistance need to be screened. In addition, the degradation solution will contain a high concentration of chromium, which cannot meet the requirements of agricultural applications

Embodiment 1

[0047] A method for preparing short peptide-growth-promoting bacteria compound fertilizer by dechroming fermentation of wet blue dander, comprising the steps of:

[0048] 1. Dechroming of wet blue dandruff

[0049] Specifically, the present application adopts the method of alkali first and then acid combination to dechrome the wet blue dandruff, including the following steps:

[0050] Alkali treatment is firstly carried out. In this step, the wet blue dander is soaked in an alkaline solution, and under the action of mechanical stirring force, the alkaline solution is gradually penetrated into the blue dander.

[0051] Wherein, the alkali solution is an aqueous calcium oxide solution; the amount of the alkali solution is 10% based on the mass of blue dander. The concentration of the alkali solution is 6-9g / L, and in the present embodiment, preferably 9g / L; the alkali treatment time is 8 -12h, in the present embodiment, preferably 12h; alkali treatment temperature is normal tem...

Embodiment 24

[0073] A short peptide-growth-promoting bacteria compound fertilizer prepared according to the above method.

Embodiment 25

[0075] The short peptide-growth-promoting bacteria compound fertilizer (dechrome wet blue dander fermented liquid) is centrifuged and then diluted, so that the free amino acid content of the diluted dechromed blue wet dander fermented liquid is respectively 20-120 mg / L, preferably The best ones are 20mg / L, 40mg / L, 60mg / L, 80mg / L, 100mg / L, 120mg / L.

[0076] It is used in agricultural planting as seed soaking liquid, hydroponic liquid or potting fertilizer.

Abstract

The invention provides an oligopeptide- growth-promoting rhizobacteria compound fertilizer prepared by dechroming and fermenting wet blue scurf and application of the oligopeptide- growth-promoting rhizobacteria compound fertilizer in planting of crops such as wheat, alfalfa and highland barley. The wet blue scurf is subjected to dechroming treatment to serve as a raw material for microbial fermentation, and the dechromed wet blue scurf fungus is fermented by bacillus pumilus to obtain dechromed wet blue scurf fermentation liquor rich in free amino acid and polypeptide, namely the oligopeptide- growth-promoting rhizobacteria compound fertilizer prepared through dechroming and fermentation of the wet blue scurf. The oligopeptide- growth-promoting rhizobacteria compound fertilizer is applied to crops such as wheat, alfalfa and highland barley. The preservation number of the bacillus pumilus BA06 is CGMCC (China General Microbiological Culture Collection Center) NO.0518. According to the invention, the conventional amino acid organic fertilizer and the growth-promoting bacterial fertilizer are organically integrated, so that multiple effects of nutrition, growth promotion, disease resistance and the like are exerted on crops.

Description

technical field [0001] The invention relates to a method for preparing short peptide-growth-promoting bacteria compound fertilizer through dechrome-fermentation of wet blue dander, a short peptide-growth-promoting bacteria compound fertilizer and application thereof, belonging to the technical field of organic liquid fertilizer production technology. Background technique [0002] The tanning industry produces tens of thousands of tons of solid chromium-containing waste every year, of which wet blue dander accounts for about 60%. The rich protein resource of wet blue dander (containing about 2-4% chromium and 90% protein) makes it have high recycling value, but because it is difficult to degrade, the traditional treatment methods (landfill or incineration) It will not only cause waste of trivalent chromium and protein resources, but also produce trivalent chromium pollution. [0003] Chemical method (acid method, alkali method) and biological method (enzyme method and microb...
