The preparation method of the organic fertilizer sequentially comprises the following steps: (1) mixing rice hull and distiller's grains, and spraying to wet to make the water content of the rice hull and the distiller's grains reach 35-40%; (2) then adding urea, a zymophyte agent and brown sugar, fermenting at 60-65 ℃ for 10-15 days while stirring for 5-6 times, granulating by a disc machine and screening to prepare an organic fertilizer; the organic fertilizer greatly converts biological wastes into nitrate nitrogen, ammoniacal nitrogen and the like, becomes necessary nutrients for crops, and solves the problem of utilization of rice hull wastes.

Description

Biological organic fertilizer and preparation method thereof

Technical Field

The invention belongs to the technical field of organic fertilizer preparation, and particularly relates to a biological organic fertilizer and a preparation method thereof.

Background

The biological organic fertilizer is a fertilizer which is compounded by microorganisms with specific functions and organic materials mainly prepared from animal and plant residues (such as livestock and poultry manure, crop straws and the like) through harmless treatment and decomposition.

The biological organic fertilizer has complete nutrient elements and provides comprehensive nutrients for crops; the biological organic fertilizer has high organic matter content, can improve soil, improve physical and chemical properties of the soil, enhance the water retention, fertilizer retention and fertilizer supply capabilities of the soil and relieve soil hardening caused by long-term use of chemical fertilizers; beneficial microorganisms in the bio-organic fertilizer enter soil and then form a mutual symbiotic proliferation relation with microorganisms in the soil, inhibit the growth of harmful bacteria and convert the harmful bacteria into beneficial bacteria, interact and mutually promote the beneficial bacteria to play a group synergistic effect, the beneficial bacteria generate a large amount of metabolites in the growth and reproduction process to promote the decomposition and conversion of organic matters, can directly or indirectly provide various nutrients and irritant substances for crops, and promote and regulate the growth of the crops.

The biological organic fertilizer improves the porosity, permeability and exchangeability of soil and the survival rate of plants, and increases beneficial bacteria, soil microorganisms and populations. Meanwhile, the dominant beneficial flora formed on the root system of the crop can inhibit the propagation of harmful pathogenic bacteria, enhance the stress resistance and disease resistance of the crop, reduce the disease index of the continuous cropping crop, and greatly relieve continuous cropping obstacles after continuous application. The biological organic fertilizer recycles agricultural wastes, reduces environmental pollution, is safe and nontoxic to people, livestock and environment, and is an environment-friendly fertilizer.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a biological organic fertilizer and a preparation method thereof. The biological waste is greatly converted into nitrate nitrogen, ammoniacal nitrogen and the like, becomes necessary nutrients for crops, and solves the problem of utilization of the rice hull waste.

The biological organic fertilizer comprises the following components in parts by weight:

40-50 parts of vinasse, 50-60 parts of rice hulls, 3-5 parts of urea, 3-5 parts of fermentation inoculum and 1-2 parts of brown sugar.

The fermentation microbial inoculum is compounded by cellulase, rhizobium and yeast, and the weight ratio of the compounding is 1:1: 1.

The preparation method of the organic fertilizer sequentially comprises the following steps:

(1) mixing rice hull and distiller's grains, and spraying to wet to make the water content of the rice hull and the distiller's grains reach 35-40%;

(2) and then adding urea, a fermentation microbial inoculum and brown sugar, fermenting at 60-65 ℃ for 10-15 days while stirring for 5-6 times, granulating by a disc machine, screening, and drying to obtain the organic fertilizer.

The organic fertilizer can also adopt the following preparation method, which comprises the following steps in sequence:

(2) then adding urea, a zymophyte agent and brown sugar, fermenting at 60-65 ℃ for 10-15 days, and stirring for 5-6 times;

(3) then 15 parts of non-drying agent is added, and the organic fertilizer is prepared by sieving after granulation by a disc machine.

The baking-free essence is prepared from the following components in parts by weight: 10 parts of calcium sulfate, 10 parts of magnesium sulfate, 7 parts of calcium chloride and 20 parts of biochar.

The free water in the granules is changed into bound water by adding the drying-free agent, so that the free water in the granules after granulation is reduced, the drying-free granulation preparation process is realized, the traditional drying equipment is not needed, the flow is simplified, the equipment investment is reduced, and the production cost and the labor cost are reduced.

The invention prepares rice hulls into organic fertilizer through biological fermentation, and has the functions of killing and preventing the underground mole cricket, root nematodes, cutworms, root maggots, termites and root longicorn. In the production environment, the environment is not harmed, and no harm or side effect is caused to people and livestock. Meanwhile, the feed can provide rich crude protein, crude fat and trace elements for plants.

The organic fertilizer is fermented. The biological waste is greatly converted into nitrate nitrogen, ammoniacal nitrogen and the like, becomes necessary nutrients for crops, and solves the problem of utilization of the rice hull waste.

Detailed Description

The process of the present invention is further illustrated below with reference to examples.

Example 1

50 parts of vinasse, 50 parts of rice hulls, 5 parts of urea, 4 parts of fermentation inoculant and 2 parts of brown sugar;
