Preparation method of bio-organic fertilizer and bio-organic fertilizer

Abstract

The present application relates to a kind of preparation methods of bio-organic fertilizer and bio-organic fertilizer, belong to the technical field of bio-organic fertilizer preparation. Including: stem tumour mustard waste and corn straw are mixed according to proportion, add grass ash and urea to carry out primary aerobic fermentation;The compost obtained is mixed with Astragalus sinicus whole plant, acid hydrolysis animal food waste liquid, after stirring fermentation, inoculate bacillus subtilis and trichoderma to carry out secondary low-temperature fermentation, and it is obtained after airing.This application significantly improves the survival rate and reproductive capacity of functional bacteria through secondary low-temperature fermentation and the effect of Astragalus sinicus and acid hydrolysis liquid, the bio-organic fertilizer prepared has high organic matter, nutrient and free amino acid content, and stable viable count, while realizing the resource recycling of preserved vegetable processing waste and kitchen animal residues, has the comprehensive effect of improving soil structure, inhibiting soil-borne diseases and promoting crop growth.
