Method for producing organic fertilizer by utilizing poultry and livestock excrement

Abstract

The invention discloses a method for producing an organic fertilizer by utilizing poultry and livestock excrement. The organic fertilizer is prepared from the following raw materials in parts by weight: 200-250 parts of dried poultry and livestock excrement, 1-2 parts of EM (effective microorganism) inoculant, 250-350 parts of straw, 50-60 parts of expanded perlite, 50-60 parts of expanded vermiculite, 35-45 parts of diatomaceous earth, 50-65 parts of bentonite, 10-15 parts of borax, 15-25 parts of magnesium sulfate, 10-13 parts of zinc sulfate, 9-15 parts of copper sulfate, 35-50 parts of gypsum, 15-20 parts of sodium humate, 60-80 parts of monopotassium phosphate, 100-150 parts of beer waste residue, and 10-13 parts of soil conditioner. According to the method, a jade component is contained in the soil conditioner, and contains massive trace elements beneficial to human bodies; the fertilizer contains an adsorption component which can effectively adsorb and immobilize toxic heavy metal elements in the soil, so that the heavy metal elements can be prevented from being absorbed by crops. The method is simple, and is low in production cost; the fertilizer does not contain harmful bacteria, and is rich in beneficial biological bacteria.

Description

technical field [0001] The invention relates to a method for producing fertilizer, in particular to a method for producing organic fertilizer by utilizing livestock and poultry manure. Background technique [0002] Agriculture is the foundation of other industries such as industry and service industry. The rise and fall of agriculture is a major event that directly affects the national economy and people's livelihood. At present, the world is facing severe problems of population increase and environmental degradation. As a country with a large population and a large agricultural country, this problem is particularly prominent. One of the main reasons for this situation is the extensive use of inorganic fertilizers. The deficiencies of this inorganic fertilizer are mainly manifested in the following aspects: 1. The nutrient is single and cannot provide comprehensive and reasonable nutrients for crops; 2. After use, the soil will be acidified or salinized, which will reduce t...
