Embodiment 1

[0034] The plant raw material used in this embodiment is corncob.

[0035] Put the plant material into the microwave vacuum tank, vacuumize to -0.02MPa, and then conduct microwave treatment, the microwave frequency is 300MHz, and the microwave treatment time is 1min; the plant material obtained after pretreatment is dried and pre-carbonized in sequence , carbonization, calcination and cooling, the temperature of each temperature measurement point, the drying zone A is 150°C, the pre-carbonization zone B is 275°C, and the carbonization zone C is 450°C. figure 1 The zone D shown is the temperature of different positions in the combustion zone. When the temperature of a certain place in the combustion zone, such as d2, is too low, open the small hole in that place, introduce air and burn it nearby, so as to raise the temperature in this place and control the bamboo to move down. The temperature of the combustion zone experienced during the process, control the combustion to raise...

Embodiment 2

[0042] The plant material used in this example is bamboo chips (about 40 cm long).

[0043]Put the plant material into the microwave vacuum tank, vacuumize until the vacuum degree is -0.001MPa, and then carry out microwave treatment, the microwave frequency is 950MHz, and the microwave treatment time is 3min;

[0044] The plant raw materials obtained through pretreatment are dried, pre-carbonized, carbonized, calcined, and cooled in sequence. The temperature at each temperature measurement point is 150°C in drying area A, 275°C in pre-carbonization area B, and 450°C in carbonization area C. The pyrolysis gas produced in the carbonization zone flows countercurrently or cross-flows with the bamboo in the drying zone from bottom to top to dry the bamboo and reach the carbonization temperature. figure 1 The zone D shown is the temperature of different positions in the combustion zone. When the temperature of a certain place in the combustion zone, such as d2, is too low, open the ...

Embodiment 3

[0051] The plant raw material used in this embodiment is pine tree, and the pine tree is first cut after the skin impurities are removed, and the length is controlled to be no more than 15 cm.

[0052] Put the plant raw material into the microwave vacuum tank, evacuate until the vacuum degree is -0.01~-0.005MPa, and then carry out microwave treatment, the microwave frequency is 550MHz, and the microwave treatment time is 1.2-2min;

[0053] The pre-treated plant raw materials are dried, pre-carbonized, carbonized, calcined, and cooled in sequence. The temperature at each temperature measurement point is 180°C in the drying area A, 325°C in the pre-carbonization area B, and 530°C in the carbonization area C. Observation during warming figure 1 The zone D shown is the temperature of different positions in the combustion zone. When the temperature of a certain place in the combustion zone, such as d2, is too low, open the small hole in that place, introduce air and burn it nearby,...

Abstract

The invention relates to a fertilizer preparing method, in particular to a method for preparing an organic fertilizer from plant charcoal and wood vinegar. The organic fertilizer is prepared through the following steps: preparation of the plant charcoal; wood vinegar treatment: first carrying out vacuum concentration on the wood vinegar to 50-65% of the original volume under the pressure of 0.01 to 0.03 MPa, and then removing tar for reserving; primary raw material matching: weighing, in parts by weight, 40-60 parts of the plant charcoal, 15-25 parts of the obtained wood vinegar and 20-30 parts of crystallization mother liquor containing 10-20% of abamectin, and stirring evenly; vacuum pressure treatment: filling the raw materials in a vacuum pressure tank for vacuum pumping to enable the vacuum degree to range from -0.015MPa to -0.025MPa, then preparing and adding 3-10 parts by weight of the rystallization mother liquor containing 10-20% of abamectin into the tank, increasing the pressure to 0.1MPa to 0.8MPa, and processing for 15-30min; and extruding granulation. The organic fertilizer which is made of the plant charcoal and the wood vinegar and is provided with increased sum of the total nutrients and the organic matter mass fraction can be prepared through the method.

Description

technical field [0001] The invention relates to a fertilizer production method, in particular to a production method for making organic fertilizer from plant charcoal and wood vinegar. Background technique [0002] Using wood vinegar organic fertilizer is one of the effective ways to reduce the use of chemical fertilizers and pesticides and improve food safety. [0003] The organic nutrients in Abamectin organic fertilizer are relatively high, and the content of crude protein, amino acid and organic matter are all high. Abamectin is a highly efficient and broad-spectrum antibiotic insecticide and acaricide. Macrolide disaccharide compound. It is a natural product isolated from soil microorganisms. It has stomach poisoning and contact killing effects on mites and insects, and has a weak fumigation effect. Interfering with the neurophysiological activities of pests has a direct killing effect on predators and parasitic natural enemies, but because there are few residues on ...
