Problems solved by technology

These processes directly mix biochar and microorganisms for adsorption or fermentation, but because biochar contains a large number of hydrophobic groups, it is not conducive to the adsorption, colonization and reproduction of microorganisms, and cannot better exert its efficacy and improve the survival rate and activity of functional microorganisms. , with certain limitations

Embodiment 1

[0022] A biochar composite bio-organic fertilizer is made from the following raw materials in parts by weight:

[0023] Ordinary organic fertilizer 60, bacterial cellulose-biochar composite material 30, Bacillus subtilis bacterial liquid with an effective viable count of 200 million / g 4, microbial growth promoter 5.

[0024] Among them, the preparation method of the bacterial cellulose-biochar composite material is as follows: the biochar powder is added into the Acetobacter xylinum liquid fermentation medium at a solid-liquid weight ratio of 1:10 and ultrasonically dispersed, and then inoculated with wood vinegar according to the inoculation amount of 3%. Bacillus, fermented and cultured at 100r / min, 20°C for 3 days to obtain a bacterial cellulose-biochar suspension, sterilized at 121°C for 10 minutes, filtered, washed, and dried to obtain a bacterial cellulose-biochar composite material.

[0025] Wherein, the Acetobacter xylinum liquid fermentation medium includes the follow...

Embodiment 2

[0032] A biochar composite bio-organic fertilizer is made from the following raw materials in parts by weight:

[0033] Ordinary organic fertilizer 70, bacterial cellulose-biochar composite material 40, Bacillus subtilis bacterial liquid with an effective viable count of 400 million / g 5, microbial growth promoter 10.

[0034] Among them, the preparation method of the bacterial cellulose-biochar composite material is as follows: add the biochar powder into the Acetobacter xylinum liquid fermentation medium at a solid-to-liquid weight ratio of 1:20 and ultrasonically disperse it evenly, and then inoculate wood vinegar with an inoculation amount of 5%. Bacillus, fermented and cultivated at 200r / min, 0°C for 6 days to obtain a bacterial cellulose-biochar suspension, sterilized at 121°C for 15 minutes, filtered, washed, and dried to obtain a bacterial cellulose-biochar composite material.

[0035] Wherein, the Acetobacter xylinum liquid fermentation medium includes the following ra...

Abstract

The invention belongs to the technical field of bio-organic fertilizers, and discloses a charcoal composite bioorganic fertilizer and a preparation method thereof. The charcoal composite bioorganic fertilizer is prepared from, by weight, 60-70 parts of an ordinary organic fertilizer, 20-30 parts of a bacterial-cellulose and bio-carbon composite material, 4-5 parts of bacillus subtilis liquid and 5-10 parts of a microbial growth promoter. The preparation method includes the following steps that the microbial growth promoter is uniformly sprayed in the bacterial- cellulose and bio-carbon composite material, after stirring, absorbing and drying, the bacillus subtilis liquid is uniformly sprayed, after stirring and adsorption, the material is uniformly mixed with the ordinary organic fertilizer, composting and fermentation are conducted, and the charcoal composite bioorganic fertilizer is obtained after the fermentation is completed. The survival rate and activity of functional microorganisms in soil can be effectively improved, the fertilizer efficiency is high, and the quality of produced crops is excellent.

Description

technical field [0001] The invention relates to the technical field of bio-organic fertilizers, in particular to a biochar composite bio-organic fertilizer and a preparation method thereof. Background technique [0002] In recent years, with the increasing amount of chemical fertilizer application, it not only affects the quality of agricultural products, but also brings serious environmental pollution. Bio-organic fertilizer is a type of fertilizer that combines specific functional microorganisms with harmless and decomposed organic materials, which has both microbial fertilizer and organic fertilizer effects. It can recycle agricultural waste, reduce environmental pollution, and is safe and non-toxic. , in line with the requirements of sustainable agricultural development, has become a hot spot of concern. Among them, the number and activity of functional microorganisms play a key role in the fertilizer efficiency of bio-organic fertilizers. At present, the production pr...
