Environment-friendly particle bioorganic fertilizer and preparation method thereof

Abstract

The invention provides an environment-friendly particle bioorganic fertilizer, which comprises the following raw materials in parts by weight: 45-65 parts of animal and poultry excrements, 20-40 parts of waste edible fungi sticks, 8-15 parts of humic acid, 5-15 parts of oil residues, 0.05-0.1 part of leavening agent strain, 0.5-1.5 parts of zinc sulfate, 0.2-0.6 part of boric acid, and 1.0-2.0 parts of ferrous sulfite. The preparation method comprises the steps of mixing animal and poultry excrements, waste edible fungi sticks, oil residues, humic acid and other trace elements to form a fermented material stack; adjusting the moisture content of the mixture to about 60-70%; heating for sterilization by virtue of biological fermentation so that the moisture content of the mixture is further reduced, and the volume is reduced; and carrying out clashing and pelleting, and drying and cooling to prepare the organic fertilizer. According to the invention, the harmless and recycling requirements can be achieved.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizers, and in particular relates to an environment-friendly granular bio-organic fertilizer and a preparation method thereof. Background technique [0002] Organic fertilizers refer to fertilizers containing a large amount of organic substances. Organic fertilizers are an important fertilizer in my country's agricultural production. For a long time, my country's traditional agricultural production has used organic fertilizers to cultivate soil fertility and increase crop yields. Organic fertilizers can fertilize the soil, nourish plants and promote the development of agricultural production. In the long history of agricultural production in our country, farmers have a long and fine tradition of using organic fertilizers. They have always relied on organic fertilizers to improve soil, fertilize soil, and produce food. Due to the rise of the chemical fertilizer industry, organic fertilizers ...

AI Technical Summary

Problems solved by technology

In recent decades, in order to pursue short-term interests, the vast number of farmers after the household contract system have seriously neglected the protection and cultivation of soil fertility, and applied a large amount of chemical fertilizers, while the application of organic fertilizers has become less and less, resulting in soil compaction, deterioration of physical and chemical properties, and soil contamination. The content of organic matter and beneficial microorganisms decreased sharply, resulting in low fertilizer utilization rate and decreased soil fertility.

There are also farmers who use a small amount of organic fertilizer, but most of them use the traditional composting method. The composting time is long, the fertilizer efficiency is low, the environment is polluted, the use is inconvenient, and the organic fertilizer that is not fully decomposed is still the cause of crop soil-borne diseases. The main source of infection, the use of insufficiently decomposed organic fertilizers often causes burnt roots and seedlings

At present, most fermented and decomposed organic fertilizers adopt the method of roller, disc, and extrusion granulation. The granule forming degree is below 70%, the granules are uneven, the productivity is low, the organic matter content is low, the energy consumption is large, and the survival rate of bacteria is low. The effect is not obvious

There are also some small-scale manufacturers who directly use the fermented and decomposed organic fertilizer without granulation, which makes it impossible to carry out large-scale mechanical sowing in large fields, resulting in low acceptance by the common people

The above defects have restricted farmers from using organic fertilizers better, so it is necessary to propose improvements
