Embodiment 1

[0044] A biological activated carbon fertilizer prepared by the following method:

[0045] (1) Stirring for the first time: mix 87 kg of bioactive carbon and 0.8 kg of microbial agent (0.3 kg of Bacillus subtilis, 0.25 kg of yeast, 0.25 kg of Hartzia sp.), 2 kg of brown sugar water (1:2 dilution) Mix and stir well.

[0046] (2) Stir for the second time: add 2 kg of water to 92 kg of the material stirred for the first time, stir to obtain the secondary mixed material, add water to adjust the water content of the secondary mixed material at 8%.

[0047] (3) Stirring for the third time: Add 3 kg of acetic acid solution (1:2 dilution) to 94 kg of uniformly stirred material and stir well. The water content of the three-time mixing mixture is 15%, and the product can be obtained.

Embodiment 2

[0049] A biological activated carbon fertilizer prepared by the following method:

[0050] (1) Stirring for the first time: mix 81 kg of bio-activated carbon and 1.0 kg of microbial agent (0.3 kg of Bacillus subtilis, 0.35 kg of yeast, 0.35 kg of Hartzia sp.), 4 kg of brown sugar water (1:2 dilution) Mix and stir well.

[0051] (2) Stir for the second time: add 3 kg of water to 90 kg of the material stirred for the first time, stir to obtain the secondary mixture, add water to adjust the water content of the secondary mixture to 10%.

[0052] (3) The third stirring: add 3.5 kg of acetic acid solution (1:2 dilution) to 93 kg of uniformly stirred material and stir well. The water content of the three-time mixing mixture is 20%, and the product can be obtained.

Embodiment 3

[0054] A biological activated carbon fertilizer prepared by the following method:

[0055] (1) Stirring for the first time: Mix 90 kg of bioactive carbon and 0.5 kg of microbial agent (0.20 kg of Bacillus subtilis, 0.15 kg of yeast, 0.15 kg of Hartzia sp.), 0.5 kg of brown sugar water (1:2 diluted ) and mix well.

[0056] (2) Stir for the second time: add 4 kg of water to 91.5 kg of the material stirred for the first time, stir to obtain the secondary mixed material, add water to adjust the water content of the secondary mixed material at 5%.

[0057] (3) The third stirring: Add 2.25 kg of acetic acid solution (1:2 dilution) to the 95.5 kg of uniformly stirred material and stir thoroughly. The water content of the three-time mixing mixture is 14%, and the product can be obtained.

Abstract

The invention discloses a preparation method of a biological activated carbon fertilizer. Single biological activated carbon is taken as a raw material; then a microbial agent, brown sugar and an acetic acid solution are added; a mixture is uniformly stirred for three times; the prepared biological activated carbon fertilizer contains nitrogen, phosphorus, potassium, calcium, magnesium, organic matters (the content being 50 percent), trace elements and multiple kinds of microbial bacteria; kept soil carbon content is increased, soil is loosened, the effectiveness of nutrients is improved while the nutrients are easily absorbed and used by crops, seed germination and growth are remarkably promoted, the slow-release property of the fertilizer can be improved, an effect that the crops can sufficiently absorb the nitrogen, the phosphorus, the potassium and medium trace elements is achieved, and the crop-producing power is promoted. After the fertilizer is applied into the soil, acid base saturation can be increased, and a big aggregate is relatively easily formed, so the adsorption and retentivity of nutrient ions in the soil can be enhanced. Compared with organic fertilizers, the biological activated carbon fertilizer does not contain ova of roundworms and escherichia coli, heavy metal content is lower than the national standard of an organic fertilizer, underground ova breeding is inhibited, and spreading of plant diseases and insect pests is controlled.

Description

technical field [0001] The invention relates to a preparation method of biological organic fertilizer, in particular to a preparation method of biological activated carbon fertilizer. Background technique [0002] At present, due to the destruction of soil structure caused by excessive application of chemical fertilizers, soil quality degradation problems such as soil secondary salinization and acidification have appeared, and the gradual accumulation of toxic and harmful substances in the soil has changed the number and structure of soil microbial populations. The increase in the number, serious soil-borne diseases, and the pollution of the land by pesticide residues have reduced the stability of natural biodiversity and ecosystems. Organic fertilizer can increase soil fertility, promote the formation of soil aggregates, make the soil have a good soil structure, and at the same time have good ventilation and water retention. Therefore, the application of organic fertilizer...
