Rapid composting microbial inoculum of agricultural wastes and method for preparing organic fertilizer from the same

Abstract

The invention relates to a rapid composting microbial inoculum of agricultural wastes and a method for preparing organic fertilizer from the same, belonging to the field of waste resource recycle. In the invention, a strain NJZ5 capable of rapidly decomposing various wastes rich in cellulose at 50 DEG C is separated. The strain NJZ5 is inoculated in a fermentation cylinder, and the obtained fermentation broth contains culturable colonies the number of which is no less than 1*109 per milliliter; after the fermentation broth and an adsorbent rice bran are mixed uniformly, the product of the rapid composting microbial inoculum of agricultural wastes can be obtained, wherein the content of the agricultural wastes in the NJZ5 strain can be no less than 1*108 per grame. The NJZ5 composting microbial inoculum can remarkably improve the composting temperature and shorten the composting period, and can control the composting period within about 30 days.

Description

1. Technical field [0001] The invention relates to a rapid composting bacterial agent for agricultural waste and a method for producing organic fertilizer thereof, belongs to the technical field of resource utilization of waste, and can be specially used for rapid resource treatment of poultry manure. 2. Background technology [0002] Livestock and poultry manure is rich in organic matter and contains various plant nutrients such as nitrogen, phosphorus, potassium, trace elements and humus. fertilizer, microbial organic fertilizer). At present, the total storage of nitrogen, phosphorus and potassium in the livestock and poultry manure discharged in my country is about 63 million tons, which is equivalent to 49 million tons of urea, 119 million tons of superphosphate and 34 million tons of potassium chloride. Therefore, livestock and poultry manure is a resource that can be developed and utilized. [0003] Modern animal husbandry is increasingly intensified, and the waste p...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to develop a technology that can quickly decompose various agricultural wastes and produce organic fertilizers. The rapid treatment of wastes can solve the current land shortage problem in my country (the accumulation of various wastes requires a large amount of land), and also solve the problem of It solves the environmental pollution problems caused by random piles of waste, and at the same time produces high value-added products to ensure the smooth development of intensive agriculture.
