Embodiment 1

[0024]The preparation steps are as follows:

[0025]1. Preparation of bacteria: HD-1 bacterial liquid for fresh overnight.

[0026]2. Preparation of an envelope material: Take a quantity of distilled water to be heated to about 90 ° C, add polyvinyl alcohol to stir, stir the stirring to it completely dissolved, prepared a mass fraction of 8% polyvinyl alcohol solution, and the seal is stored for cooling to room temperature.

[0027]3. Slag pretreatment: The water content of 60% is dried at a high temperature of 150 ° C for 72 h.

[0028]4, precursive treatment: use a pulverizer to pulverize the zeolite, and the slag is divided into 60 mesh powder.

[0029]5. Comparative: 20 parts of zeolite, 75 parts of the biogoura, and a quantity of HD-1 bacteria were added during the mixing process.

[0030]6. Put the compound of the compound into the disc granulator for granulation, and add 8% polyvinyl alcohol, compix by 0.2ml · g-1, The particle size range is 3 ~ 5mm, so that the number of effective live bacter...

Embodiment 2

[0033]The preparation method is as in Example 1, which is different:

[0034]1. Preparation of bacteria: HD-1 bacterial liquid for fresh overnight.

[0035]2. Preparation of the envelope material: Take a certain amount of distilled water to heat about 90 ° C, add polyvinyl alcohol to stir, stir the stirring to it completely dissolved, prepared a mass fraction of 10% polyvinyl alcohol solution, and the seal is stored for cooling to room temperature.

[0036]3. Slag pretreatment: The water content of 65% is dried at 150 ° C for 72 h.

[0037]4, precursive treatment: use a pulverizer to pulverize the zeolite, and the slag is divided into 60 mesh powder.

[0038]5. Comparative: 25 parts of zeolite, 70 parts of the bridges are mixed, and a certain amount of HD-1 bacteria is added during the mixing process.

[0039]6. Put the complicated material into the disc granulator for granulation, and add 10% polyvinyl alcohol, complicate 0.2ml · g-1, The particle size range is 3 ~ 5mm, so that the number of effecti...

Abstract

The invention discloses a method for preparing organic fertilizer with pesticide-degrading bacteria from pig farm biogas residue, and belongs to the technical field of bio-organic fertilizer. Using zeolite as organic fertilizer carrier, biogas residue as substrate, HD-1 bacterial liquid as additive, and polyvinyl alcohol as coating material, an organic fertilizer with pesticide-degrading bacteria was prepared. The polyvinyl alcohol adopted in the invention is stable in nature at normal temperature, non-toxic and harmless, has a certain hierarchical structure, can fill the internal gap of the fertilizer, and improves the stability and fertilizer retention of the fertilizer structurally. Zeolite can reduce the fixation of available phosphorus in soil, and has a certain exchange and adsorption effect on ammonium nitrogen. The ammonium root ions dissolved in biogas residue will be absorbed and retained by zeolite, thereby controlling the release rate of nutrients in fertilizers and improving the slow-release performance. Pesticide-degrading bacteria organic fertilizer can not only improve soil, enhance soil scab resistance and compaction ability, improve soil enzyme activity, but also degrade residual pesticide substances in soil through microorganisms.

Description

Technical field[0001]The present invention belongs to the field of biological organic fertilizers, and more particularly to a method of combining a biogaramine, a pesticide degradation bacterium HD-1 in a raising field.Background technique[0002]The farmland farm system in my country is generally two mature, and the use of chemical fertilizers in the long term will not only reduce soil soil, alter the granular structure of soil, so that the degree of soil strip and salt is increased, and the activity of microorganisms in the soil will also inhibit the activity of microorganisms in the soil. Soil ecological environment causes serious damage. The study found that the cost of administration of fertilizers increased year by year, but the benefits were decreasing. At the same time, a large number of pesticides remain in the soil in my country, such as the harm of soil environment and human health. Applying organic fertilizers can increase the content of nitrogen phosphorus in the soil, im...
