Embodiment 1

[0028] (1) Cut the air-dried pig’s hair into small pieces of 1-2cm, place it in a high-temperature-resistant muffle furnace, and carbonize it at 300°C for 2 hours under anaerobic conditions. After cooling to room temperature, it is crushed and sieved to form Pig vegetable biochar, wherein the particle size of pig vegetable biochar is 1 mm, and the average pore diameter is 4.5 μm.

[0029] (2) In parts by weight, the zeolite pulverized and sieved to form a zeolite powder with a particle diameter of 0.1-1mm, the bentonite pulverized and sieved to form a bentonite powder with a particle diameter of 0.1-0.5mm, 15 parts of zeolite powder, 20 1 part of bentonite powder, 3 parts of amino acid and 0.5 part of citric acid are mixed to form auxiliary materials.

[0030] (3) Add 50 parts of vetch biochar to the above auxiliary materials, add 15 parts of water, and stir to form a granular soil conditioner based on vetch biochar with a particle size of 2 mm.

Embodiment 2

[0032] (1) Cut the air-dried pig’s hair into small pieces of 1-2cm, place it in a high-temperature-resistant muffle furnace, and carbonize it at 700°C for 2 hours under anaerobic conditions. After cooling to room temperature, it is crushed and sieved to form Pig vegetable biochar, wherein the particle size of pig vegetable biochar is 0.1mm, and the average pore diameter is 0.5μm.

[0033] (2) In parts by weight, the zeolite pulverized and sieved to form a zeolite powder with a particle diameter of 0.1-1mm, the bentonite pulverized and sieved to form a bentonite powder with a particle diameter of 0.1-0.5mm, 25 parts of zeolite powder, 30 10 parts of bentonite powder, 10 parts of amino acid and 1.5 parts of citric acid are mixed to form auxiliary materials.

[0034] (3) Add 60 parts of vetch biochar to the above auxiliary materials, add 20 parts of water, and stir to form a granular soil conditioner based on vetch biochar with a particle size of 5 mm.

Embodiment 3

[0036] (1) Cut the air-dried pig’s hair into small pieces of 1-2cm, place it in a high-temperature-resistant muffle furnace, and carbonize it at 500°C for 2 hours under anaerobic conditions. After cooling to room temperature, it is crushed and sieved to form Pig vegetable biochar, wherein the particle size of pig vegetable biochar is 0.5mm, and the average pore diameter is 0.6μm.

[0037] (2) In parts by weight, the zeolite pulverized and sieved to form a zeolite powder with a particle diameter of 0.1-1 mm, the bentonite crushed and sieved to form a bentonite powder with a particle diameter of 0.1-0.5 mm, 20 parts of zeolite powder, 25 1 part of bentonite powder, 5 parts of amino acid and 1 part of citric acid are mixed to form auxiliary materials.

[0038] (3) Add 50 parts of vetch biochar to the above auxiliary materials, add 60 parts of water, and stir to form a solution-like soil conditioner based on slaw biochar with a solid content of 45%.

Abstract

The invention provides a soil conditioner based on salsola collina biological carbon and a preparation method thereof. The soil conditioner based on the salsola collina biological carbon is prepared from salsola collina biological carbon, amino acid, citric acid, bentonite and zeolite. The preparation method specifically comprises the following steps of cutting air-drying salsola collina into 1-2cm small sections, putting into a high temperature-resistant sealed container, carbonizing, cooling to room temperature, crushing, and screening, so as to form the salsola collina biological carbon; crushing and screening the zeolite to form zeolite powder, crushing and screening the bentonite to form bentonite powder, and mixing the zeolite powder, the bentonite powder, the amino acid and the citric acid, so as to form auxiliary materials; adding the salsola collina biological carbon into the auxiliary materials, adding water, and stirring, so as to obtain the soil conditioner based on the salsola collina biological carbon. The soil conditioner has the advantages that the preparation method is simple, and the cost is low; by applying the salsola collina into the soil conditioner, the medical property of the soil conditioner is realized, and the application field of the salsola collina is widened.

Description

technical field [0001] The invention belongs to the technical field of soil improvers, and in particular relates to a soil improver based on the biochar of piglets and a preparation method thereof. Background technique [0002] The release of carbon dioxide by farmland soil organic carbonization is an important way of greenhouse gas emissions. As the implementation of greenhouse gas emission tasks becomes easier, how to reduce greenhouse gas emissions in land and increase carbon sinks in terrestrial ecosystems has become a hot topic in current research. [0003] Biochar is a fine-grained, porous carbonaceous material obtained by pyrolyzing biomass under oxygen-free or oxygen-limited conditions. The main components of biochar are carbon, hydrogen, oxygen, and ash elements such as potassium, calcium, sodium, magnesium and silicon. The elemental composition of biochar is related to the carbonization temperature and the soil type and plant species of the fabric's growth place. ...
