Embodiment

[0029] Put part of the biomass corn stalk and soybean stalk into the raw material crushing structure 1, and crush it to a particle size of about 15mm;

[0030] Then add a certain amount of catalyst and plasticizer from the tempering material bin 2 to carry out tempering pretreatment;

[0031] Conditioning, stirring, mixing and evenly placing for a period of time, the pretreated straw is spirally transported to the pyrolysis and carbonization furnace 5 through the screw feeding structure 4, and the straw is set to carry out gradient heating in the pyrolysis and carbonization furnace 5, and the carbonization temperature is kept at 550°C. 3h deoxidation carbonization treatment, the processed wood charcoal powder is transported to the cooling part for cooling through the spiral discharge structure, and after cooling for a certain period of time, it is put into the crushing part for crushing to a fine granular shape of about 5mm;

[0032]In the microbial expansion device, Bacillus ...

Description

technical field [0001] The invention relates to the fields of utilization of biomass resources and soil improvement, in particular to a soil conditioner preparation system for biomass charcoal coupled with microorganisms. Background technique [0002] With the continuous development of the economy, the irrational use of soil by humans has led to increasingly serious soil degradation problems, mainly manifested in soil hardening, salinization, acidification, chemical pollution and erosion, which seriously limit the productivity of the land. [0003] The world has 730 million hm of arable land 2 , but an average of nearly 5 million hm per year 2 of the land is degraded to produce food. Therefore, how to maintain soil quality, improve acid-base soil, remove soil toxicity, and reduce the spread of soil-borne diseases has become the focus of attention. [0004] There are many ways to improve soil properties, such as the combination of deep tillage and no-tillage, expanding gre...
