Embodiment 1

[0034] A preparation method for microbial fermented organic fertilizer, comprising the following steps:

[0035] Step 1. Take the stomach content, intestinal content and animal feces of the slaughtered cattle and sheep with a weight ratio of 2:1:1, add them to a drum sieve with an aperture of 30mm, separate and screen them, and then transfer them to a drum-type high-temperature furnace and heat them to 180 °C, rotate at a speed of 6 rpm and keep warm for 2 hours, and dry the stomach contents, intestinal contents and animal feces until the moisture content is 55%;

[0036] Step 2, adding the dried stomach content, intestinal content and animal feces into a high-temperature fermentation tank, and performing aerobic fermentation at 80°C for 2 hours to obtain an aerobic fermentation product;

[0037] Step 3, transfer the aerobic fermentation product to the fermentation workshop, and add 1L of multifunctional microbial inoculant per ton of aerobic fermentation product, then mix eve...

Abstract

The invention discloses a microbial fermentation organic fertilizer and a preparation method thereof. The method comprises steps as follows: (1), stomach content, intestinal content and animal dung of slaughtered animals are added to a drum screen to be separated and screened and then are conveyed to a drum type high-temperature furnace to be heated, and the stomach content, the intestinal content and the animal dung are dried; (2), the dried stomach content, intestinal content and animal dung are added to a high-temperature fermentation tank for aerobic fermentation, and aerobic fermentation products are obtained; (3), the aerobic fermentation products are conveyed to a fermentation workshop, a multifunctional microorganism inoculation agent is added, the mixture is uniformly mixed, compost is fermented, and the organic fertilizer is prepared. The organic fertilizer is prepared from the stomach content, the intestinal content and the dung of the animals, the microorganism inoculation agent is added, the composting time of the fertilizer is shortened, the environment pollution problem caused by stomach content, the intestinal content and the dung of the animals is solved, no toxic or harmful substances are discharged in the composting process, the organic fertilizer is completely harmless, nutrients can be preserved, the content of organic matters in the fertilizer is increased, and accordingly, the quality of the fertilizer is improved.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a low-cost and high-efficiency microbial fermented organic fertilizer and a preparation method thereof. Background technique [0002] Organic fertilizer refers to the use of various animal wastes (including animal manure, animal processing waste) and plant residues (cake fertilizer, crop straw, fallen leaves, dead branches, peat, etc.), using physical, chemical, biological or a combination of the three. Some treatment technologies, through certain processing techniques (including but not limited to composting, high temperature, anaerobic, etc.), eliminate harmful substances (pathogens, pest eggs, weed seeds, etc.) to achieve harmless standards A type of fertilizer formed. [0003] At present, the fermentation time for most high-quality organic fertilizer composts in my country to reach the harmless target is generally 45-60 days, which is a long cycle and high cost. The co...
