Embodiment 1

[0017] An organic charcoal microbial fertilizer and a preparation method thereof, comprising the steps of:

[0018] (1) Preparation of the carrier: Remove larger impurities and stones from corn stalks, decomposed chicken manure and peat soil, then air-dry them, and prepare the carrier by taking corn stalks, decomposed chicken manure and peat soil in a weight ratio of 1:1:1;

[0019] (2) Preparation of bacterial suspension: activate the growth-promoting bacteria in the culture medium, and prepare the CFU per milliliter at 2×10 8 —3×10 8 bacterial suspension.

[0020] (3) Inoculate the suspension prepared in (2) into the carrier prepared in (1), the ratio is (3-5) ml / (4-8) g, mix well and store at 18°C-22°C Leave it for 16-20 days.

Embodiment 2

[0022] An organic charcoal microbial fertilizer and a preparation method thereof, comprising the steps of:

[0023] (1) Preparation of the carrier: Remove larger impurities and stones from corn stalks, decomposed chicken manure and peat soil, then air-dry them, and prepare the carrier by taking corn stalks, decomposed chicken manure and peat soil in a weight ratio of 1:1:1;

[0024] (2) Preparation of bacteria suspension: Azotobacter, phosphate-soluble bacteria, potassium-solubilizing bacteria and anti-rot bacteria with the ratio of effective viable bacteria number 1:1:1:1 were activated and cultivated in potato dextrose agar medium to prepare CFU per ml at 2 x 10 8 —3×10 8 bacterial suspension.

[0025] (3) Inoculate the suspension prepared in (2) into the carrier prepared in (1), the ratio of the suspension to the carrier is 2ml: 3g, mix well and place it at 20°C for 18 days. During this period, agitation is performed every 2 hours to fully contact with the air to prevent...

Abstract

The invention discloses an organic carbon microorganism fertilizer and a preparation method thereof. The preparation method comprises the following steps that: (1) carrier preparation: after large impurities and stones in corn straws, decomposed chicken manures and peat soil are removed, carrying out air drying, and preparing a carrier from one part by weight of corn straw, one part by weight of decomposed chicken mature and one part by weight of peat soil; (2) bacterial suspension preparation: carrying out activated culture on growth-promoting bacteria in a culture medium, preparing the bacterial suspension of which the CFU (colony-forming unit) in each milliliter is 2*10<8>-3*10<8>; (3) inoculating the prepared bacterial suspension into the carrier prepared in (1) at the ratio of 2ml / 3g,and standing for 18 days at the temperature of 20 DEG C after even mixing. According the preparation method, through reasonable bacterial strain and carrier collocation, the prepared microorganism fertilizer has good adsorption capacity, is favorable for culture survival and function exertion, and contains bacterial strains with the functions of nitrogen fixation, phosphate solubilization, potassium dissolving and bacteria resistance, and the supply amount of plant nutrients is increased through the vital movement of the bacterial strains.

Description

technical field [0001] The invention relates to the technical field of microbial fertilizers, in particular to an organic carbon microbial fertilizer and a preparation method thereof. Background technique [0002] Due to the application of a large amount of chemical fertilizers, soil compaction, water quality decline, agricultural products are seriously polluted, and the entire farmland ecological environment and people's living environment are affected. How to maintain the sustainable development of my country's agriculture has attracted great attention from governments at all levels. Especially after my country's accession to the WTO, my country's agriculture has been severely challenged. To develop export-earning agriculture, we must vigorously promote the development of green food and pollution-free food. Moreover, under the impact of the international financial crisis, the traditional chemical fertilizer industry is in deep trouble. Fertilizers have a very good room for ...
