Biological organic fertilizer and preparation method thereof

Abstract

The invention belongs to the technical field of biological fertilizer processing, and specifically relates to a biological organic fertilizer and a preparation method thereof. The biological organic fertilizer is composed of the following raw materials: manure, organic fermented materials, a biological leavening agent, animal hairs, tobacco stem or tobacco leaf, and trace elements. The preparation method comprises the following steps: (1) mixing composted fertilizer and a nicotine solution, drying the mixture at a temperature of 40 to 50 DEG C until the water content is reduced to 40 to 50% so as to obtain a mixed fertilizer, and saving the mixed fertilizer for later use; (2) mixing micro element powder with water according to a ratio of 1:1, adding a composite amino acid water solution, and mixing; (3) mixing the mixed fertilizers obtained in the step (1) and (2), evenly stirring, and fermenting the mixture; (4) drying: dehydrating the raw materials fermented in the step (3) in the air; (5) grinding, screening, packaging, and storing. According to the preparation method, animal hairs are made into amino acid, then micro elements are added to prepare amino acid salts, and the fertilizer can improve the acidic and alkaline properties of soil.

Description

Technical field: [0001] The invention belongs to the technical field of biological fertilizer processing, and in particular relates to a biological organic fertilizer and a preparation method thereof. Background technique: [0002] Bio-organic fertilizer, also commonly known as farmyard manure, refers to a kind of microbial fertilizer that contains a large amount of biomass, animal and plant residues, excrement, biological waste and other substances as the source and is compounded by harmless treatment and decomposed organic materials. It is a slow-acting fertilizer with organic fertilizer effect. Bio-organic fertilizer not only contains essential elements and trace elements for plants, but also rich in organic nutrients. Organic fertilizer is the most comprehensive fertilizer. In the process of modern agricultural production, chemical fertilizers such as urea, ammonium carbonate, and compound fertilizers are used for a long time. Although the fertilizer effect is fast and t...

Problems solved by technology

In the process of modern agricultural production, chemical fertilizers such as urea, ammonium carbonate, and compound fertilizers are used for a long time. Although the fertilizer effect is fast and the nutrient content is high, the duration of the fertilizer effect is short, and it will destroy the soil structure, causing the plow layer to become shallow, and the planted The taste of agricultural products is poor, which reduces the quality of agricultural products; bio-organic fertilizers can not only provide comprehensive nutrition for crops, but also have long fertilizer effects, which can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and are green. The main nutrient for food production, the research and development of special bio-organic fertilizers suitable for crop growth will be of great significance to the production of my country's agricultural industry
