Eggshell high-calcium type organic fertilizer and preparing method thereof

Abstract

The invention relates to eggshell high-calcium type organic fertilizer and a preparing method thereof, and belongs to the technical field of organic fertilizer production. According to the organic fertilizer, 150-200 parts of waste eggshells serve as the main material in match with 60-100 parts of peanut bran, 95-140 parts of poultry excrement, 100-145 parts of organic waste and 1-5 parts of microbial inoculants. The eggshell high-calcium type organic fertilizer is manufactured in the following steps that the eggshells are mixed with the peanut bran, the poultry excrement and the organic waste after being dried and ground to be stirred, the microbial inoculants are sprayed, and the high-calcium type organic fertilizer is manufactured through pool heap secondary fermentation. According to the eggshell high-calcium type organic fertilizer and the preparing method, the calcium element and magnesium element in waste eggshells serve as the main raw material, the safe, nuisanceless and multifunctional effective organic fertilizer capable of enhancing the water storage fertilizer maintenance capacity of soil is prepared, the limits that a traditional chemical acidic soil conditioner contains harmful substance and is singular in product effect are broken through, the problem that ordinary organic fertilizer is slow in fertilizer efficiency is solved while the problem of pollution, caused by the waste eggshells, to the environment is thoroughly solved.

Description

technical field [0001] The invention relates to an organic fertilizer and a preparation method thereof, in particular to a high-calcium organic fertilizer prepared from eggshell waste and industrial and agricultural organic waste as main raw materials and a preparation method thereof, belonging to the technical field of organic fertilizer production. Background technique [0002] Since the reform and opening up, with the improvement of people's living standards and the development of the food industry, the demand for eggs in life has continued to increase. According to statistics, my country's total egg production in 2014 was more than 40 million tons, and egg shells accounted for 12-13% of the total eggs. According to this ratio, my country will produce nearly 5 million tons of egg shells every year. In recent years, people have increased their awareness of environmental protection, and the research on the comprehensive utilization of discarded eggshells has gradually attra...

Problems solved by technology

In recent years, people have increased their awareness of environmental protection, and the research on the comprehensive utilization of discarded eggshells has gradually attracted attention. However, only some eggshells from egg product factories have been used as livestock and poultry feed additives and calcium sources for lactic acid bacteria fermentation, while most eggshells However, it is abandoned as garbage, especially the breeder hatchery, which produces thousands of tons of eggshells every day. However, these piles of eggshell garbage are difficult to decompose in the natural state, and eventually lead to waste disposal. Waste of difficult and waste resources and serious pollution of the ecological environment
