Bamboo residue organic fertilizer and method for preparing same

Abstract

The invention relates to a method for producing an organic fertilizer by bamboo residues. The method comprises the following steps of: drying and grinding bamboo residues of bamboo leaves, bamboo roots, bamboo stems, bamboo shoots and the like, which are generated during bamboo processing; mixing the bamboo residues and excrement o animals in a ratio; and performing processes of fermentation, drying, granulation and the like of the mixture to obtain the organic fertilizer. The method has the advantages of improving contents of nutrients of silicon, calcium, magnesium, iron and the like in the organic fertilizer, improving the abilities of absorbing and retaining water of the organic fertilizer, enhancing the abilities of improving acid soil and plastic greenhouse soil, effectively adsorbing odor gas, ammonia gas and the like, which are generated during the production of the organic fertilizer, by utilizing the structural characteristics of bamboos, reducing the negative effects caused by the organic fertilizer, reducing loss of nutrients during the fermentation of the organic fertilizer, and improving the comprehensive benefits of the production of the organic fertilizer.

Description

technical field [0001] The invention relates to an organic fertilizer and a preparation method thereof, in particular to a bamboo residue organic fertilizer and a preparation method thereof. Background technique [0002] my country is a big country in the bamboo industry, and the area of ​​bamboo forests ranks first in the world. Bamboo is widely used in industries such as construction, food and textile industries, resulting in a large amount of bamboo waste (bamboo residue) such as bamboo leaves, bamboo stems and bamboo roots. This waste is mainly landfilled or incinerated without being fully utilized. Bamboo fiber structure is unique, with excellent ventilation, water absorption, moisturizing and deodorizing characteristics, rich in silicon, magnesium, iron, zinc and other medium and micronutrient elements; bamboo extract is slightly alkaline, making it an excellent acidic soil amendment , and can effectively absorb ammonia and odor during the preparation of livestock manu...

Problems solved by technology

[0004] At present, the method of producing organic fertilizer is a lot, but the method that uses bamboo dregs to produce organic fertilizer as main component has not yet been reported and produced and used, and the Chinese patent that sees has only disclosed patent " bamboo fiber fertilizer on January 8th, 2009 "Manufacturing Method" (publication number: 200810000917.6), but this patent application mainly uses fresh tender bamboo, the source of raw materials is limited, and the agricultural wastes used are rice bran, soybean dregs, rapeseed dregs, etc., and livestock manure is not used. Components, while livestock manure is the most important organic fertilizer raw material with high nutrient content, and with the intensive development of my country's livestock breeding industry, a large amount of livestock manure seriously pollutes the environment and needs to be treated urgently
