Problems solved by technology

However, crop stalks, including tail vegetables, may contain pesticide residues, and manure also has the risk of contamination by heavy metals and antibiotic residues
Moreover, since the release of mineral nutrients requires soil microbial degradation processes, the fertilizer efficiency is relatively slow
During the natural composting process of traditional organic fertilizers, usually up to 30% of nitrogen nutrients are lost in the form of ammonium nitrogen, and the utilization rate of nutrients is low

Embodiment 1

[0049] Embodiment 1, preparation plant source bio-organic fertilizer (biochar+plant material (tail vegetable))

[0050] Prepare plant source bio-organic fertilizer according to the following steps:

[0051] (1) Mechanically pulverize the plant organic matter tail vegetables, and then mix with biochar to obtain a premix; wherein, the mass of biochar is 20% of the total mass of the premix.

[0052] (2) carry out composting fermentation to the premix in step (1);

[0053] Before composting and fermentation, the following steps are also included:

[0054] 2-1) Add water to the premixed material obtained in step 1), and control the water content of the mixture to be 75%.

[0055] 2-2) Add an organic matter degrading enzyme (plant proteolytic enzyme) to the premix treated in the above 2-1) in an amount of 1% of the mass of the premix (ie 3 million IU / kg premix) .

[0056] 2-3) Add a biodegradation agent to the mixture obtained in the above 2-2): earthworms and fermenting microor...

Embodiment 2

[0062] Embodiment 2, preparation plant source / animal source bio-organic fertilizer (biochar+tail vegetable+manure)

[0063] Prepare plant source / animal source bio-organic fertilizer according to the following steps:

[0064] (1) Break up large pieces of manure such as animal-source organic matter cow manure, chicken manure, and pig manure, pass through a 5cm large-hole sieve, and mechanically pulverize plant-source organic matter tail vegetables; then crush animal-source organic matter and plant-source Organic matter is mixed with biochar to obtain a premix; wherein, the mass ratio of animal source organic matter to plant source organic matter is 1:2, and the mass of biochar is 20% of the total mass of the premix.

[0065] (2) carry out composting fermentation to the premix in step (1);

[0066] Before composting and fermentation, the following steps are also included:

[0067] 2-1) Add water to the premixed material obtained in step 1), and control the water content of the ...

Abstract

The invention discloses a rhizo-spherical beneficial microorganism-charcoal composite organic fertilizer and a preparation method thereof. The rhizo-spherical beneficial microorganism-charcoal composite organic fertilizer comprises the following steps that 1, organic matter and charcoal are mixed to obtain a premix; 2, composting fermentation the premix in the step 1; 3, rhizo-spherical microorganisms are added in the fermentation product in the step 2 to obtain the rhizo-spherical beneficial microorganism-charcoal composite organic fertilizer. Plant sourced and animal sourced organic matter are subjected to mixed fermentation, the raw materials are innocently treated to form charcoal, the charcoal effect of the charcoal is played, and the clean organic fertilizer is produced. The rhizo-spherical microorganisms promoting plant growth are added in the fermentation product, the organic matter degradation and mineralization process is catalyzed, the fertilizer still has activity after being applied to soil, and the organic matter mineralization efficiency and soil phosphate degradation are improved.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer preparation, in particular to a rhizosphere beneficial microorganism-biochar composite organic fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is one of the material basis of agricultural production. Before the world green revolution, organic fertilizer was the mainstream of fertilizer. After the Green Revolution, chemical fertilizers replaced organic fertilizers, which increased yields but also caused degradation of soil fertility and environmental problems. [0003] On the one hand, the extensive use of inorganic fertilizers causes the degradation of soil fertility and the pollution of the environment. my country is facing the situation of soil fertility degradation, low efficiency of chemical fertilizer utilization, soil heavy metal and antibiotic pollution. The reason for this evil result is the use of a large amount of chemical fertilizers, ...
