Embodiment 1

[0022] Step 1. Substrate preparation: Dry or dry the pig manure naturally, sterilize it with ultraviolet light for 30 minutes, and turn it twice during the irradiation period to obtain the fermentation substrate;

[0023] Step 2. Secondary fermentation: sterilize the above-mentioned fermentation substrate at 121°C for 20 minutes, cool to room temperature, add water, and stir evenly to obtain a solid fermentation medium. The water content of the solid fermentation medium is 5%, and insert Lactobacillus The seed liquid of Candida utilis was first anaerobically fermented for 48 hours at a fermentation temperature of 25°C; then the seed liquid of Candida utilis was introduced, and sterile air was fed into it, and it was aerobically fermented for 48 hours at a fermentation temperature of 25°C; the fermentation product was obtained ;

[0024] Step 4, drying: drying the fermentation product, the drying temperature is 55°C, and the water content after drying is not higher than 8%;

Embodiment 2

[0027] Step 1. Substrate preparation: Dry or dry the pig manure naturally, sterilize it with ultraviolet light for 80 minutes, and stir it 3 times during the irradiation period to obtain the fermentation substrate;

[0028] Step 2. Secondary fermentation: sterilize the above-mentioned fermentation substrate at 121°C for 15 minutes, cool to room temperature, add water, and stir evenly to obtain a solid fermentation medium. The water content of the solid fermentation medium is 8%, and insert Lactobacillus The seed liquid of Candida utilis was first anaerobically fermented for 48 hours at a fermentation temperature of 30°C; then inserted into the seed liquid of Candida utilis and fed with sterile air, and fermented aerobically for 60 hours at a fermentation temperature of 30°C; the fermentation product was obtained ;

[0029] Step 4, drying: drying the fermentation product, the drying temperature is 55°C, and the water content after drying is not higher than 8%;

[0030] Step 5....

Embodiment 3

[0032] Step 1. Substrate preparation: Dry or dry the pig manure naturally, sterilize it with ultraviolet light for 120 minutes, and stir it 3 times during the irradiation period to obtain the fermentation substrate;

[0033] Step 2. Secondary fermentation: sterilize the above-mentioned fermentation substrate at 121°C for 30 minutes, cool to room temperature, add water, and stir evenly to obtain a solid fermentation medium. The water content of the solid fermentation medium is 10%, and insert Lactobacillus The seed liquid of Candida utilis was first anaerobically fermented for 48 hours at a fermentation temperature of 35°C; then inserted into the seed liquid of Candida utilis and fed with sterile air, and fermented aerobically for 72 hours at a fermentation temperature of 45°C; the fermentation product was obtained ;

[0034] Step 4, drying: drying the fermentation product, the drying temperature is 60°C, and the water content after drying is not higher than 8%;

Abstract

The invention discloses a preparation method of a bioorganic fertilizer. The method comprises the following steps: 1, preparing a substrate: naturally solarizing or drying pig dung, carrying out ultraviolet lamp irradiation disinfection for 30-120min, and overturning the pig dung 2-3 times in the irritation process to prepare the fermentation substrate; 2, carrying out two stage fermentation: sterilizing the fermentation substrate at 121DEG C for 20-30min, cooling the sterilized substrate to room temperature, adding water, and uniformly stirring to prepare a solid fermentation medium, inoculating a lactobacillus strain liquid, carrying out anaerobic fermentation for 48h, inoculating a Candida utilis strain liquid, introducing aseptic air, and carrying out aerobic fermentation for 48-72h to obtain a fermentation product; 4, drying: drying the fermentation product at 55-60DEG C; and 5, proportioning: adding a biological regulator to the dried fermentation product according to a weight ratio of 100:(0.2-1) in order to prepare the bioorganic fertilizer, wherein the biological regulator is photosynthetic bacteria and azotobacteria. The bioorganic fertilizer prepared in the invention can greatly improve the output per 666.7m<2> of land of crops.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a preparation method of biological organic fertilizers. Background technique [0002] Organic fertilizers are mainly derived from plants and (or) animals, and are applied to the soil to provide plant nutrition as a carbon-containing material whose main function is. It is processed from biomass, animal and plant waste, and plant residues to eliminate toxic and harmful substances, and is rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. nutritional elements. It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and is the main nutrient for green food production.
