Abstract

The invention discloses a method for making an organic fertilizer by using a packed compost technology. The method is characterized in that cow manure is taken as a nitrogen source, mushroom residue is taken as a carbon source, cow manure and mushroom residue are uniformly mixed to obtain a mixture, a decomposed microbe inocula is uniformly spread or sprayed in the mixture, a compost is uniformlystirred, the compost is subjected to high-temperature aerobic fermentation, and the temperature of the compost is kept at 50-60 DEG C for fermentation; the compost is subjected to turning for one timeevery day when the temperature exceeds 60 DEG C, and turning for one time every two days when the temperature is 50-60 DEG C, cooling is carried out after fermentation for several days, when the temperature of the compost is reduced to 50 DEG C, packaging processing is carried out, and no turning is carried out after packaging processing; and when the compost temperature is cooled to the ambienttemperature, the fermentation is finished. The packed compost technology has the advantages of simple process, economic performance, and less land occupation, uses limited land occupation for massiveproduction, and can greatly increase the efficiency and economic benefit of organic fertilizer production manufacturers.

Description

technical field [0001] The invention belongs to the field of organic fertilizer production, and in particular relates to a method for producing organic fertilizer by using bagged composting technology. Background technique [0002] In recent years, the dairy farming industry has shown a trend of vigorous development, and the discharge of cow manure has also increased. Generally, cow dung has a high water content and poor air permeability. Direct composting will cause an anaerobic environment and affect the composting process. So, adding a dry, absorbent, supportive, and low-cost conditioner to it will make composting go smoothly. Mushroom slag is a good conditioning agent. Mushroom slag is referred to as mushroom slag, also known as mushroom residue, fungus chaff, leftovers, etc. It refers to the organic solid waste left after the cultivation of various edible fungi and decomposed by microorganisms. . For every 100kg of compost, after harvesting 100kg of fresh mushrooms, ...
