Embodiment 1
[0018] A biochar soil improvement organic fertilizer, comprising the following steps:
[0019] (1) Production of biochar: After crushing the plantstraw, mix it with an active agent with a mass of 1.7% of the straw; then, place the mixture in a carbonization furnace for carbonization to make biochar; the mass ratio of the active agent is: Potassiumphosphate: sulfuric acid: hydrochloric acid is 11:1:3; among them, the carbonization process: the first step of dehydration stage, the temperature is 190 ° C, the time is 32 minutes; the second step is the carbonization stage, the temperature is 520 ° C, the carbonization time is 4 hours; Reduce the temperature in the carbonization furnace to 110°C within 1 minute for 50 minutes; after the process is finished and cooled, biochar is produced;
[0020] (2) Biochar treatment: Soak biochar in multi-strain culture solution for 1 hour, take it out, and incubate it in a constant temperature box at 32°C for 13 hours to obtain bioactive bioc...
Embodiment 2
[0024] Present embodiment 2 is compared with embodiment 1, and step changes in the following aspects:
[0025] The carbonization process parameters described in step (1) are:
[0026] The first dehydration stage, the temperature is 210°C, and the time is 35min; the second carbonization stage, the temperature is 540°C, and the carbonization time is 5h; the third step is the cooling stage, the temperature in the carbonization furnace is reduced to 130°C within 1min, and the time is 60min; the end of the process After cooling, biochar is produced.
[0027] The soaking time of the biochar bacteria solution and trace element solution in step (2) is: 1.5 hours of bacteria solution soaking, and 8 hours of trace element soaking.
[0028] In step (3), the mass fraction of the organic ingredient preparation is:
[0029] 44 parts of fermented straw, 38 parts of fermented sawdust, 24 parts of peat, 18 parts of humic acid, and 11 parts of cake fertilizer.
[0030] Others are the same as...

Abstract
The invention discloses a bio-charcoalorganic fertilizer for soil improvement. A preparation and application method includes the following steps: 1) production of bio-charcoal: mixing an activator component with straw, and performing carbonization including a dehydration stage, a carbonization stage and a temperature reduction stage; 2) treatment of the bio-charcoal: soaking the bio-charcoal respectively in a multi-bacterial strain culture solution and a microelement solution, wherein the ratio of the bio-charcoal soaked with the multi-bacterial strain solution to the microelement bio-charcoal is 3:2, and preparing a bio-charcoal fertilizer; 3) preparation of organic and inorganic components: preparing the organic and inorganic components in the fertilizer; and 4) soil improvement: mixingthe bio-charcoal fertilizer, the organic component and the inorganic component according to mass ratio of 1:5:2, deeply ploughing farmland by 30-35 cm, and applying the bio-charcoal organic fertilizer by 120-140 kg per Mu.
Description
technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to an organic fertilizer for biochar soil improvement. Background technique [0002] Biochar refers to the solidcarbonization product produced by bio-organic materials after high-temperature pyrolysis in an anoxic or anaerobic environment. Biochar can solidify carbon dioxide and reduce the greenhouse effect; it can absorb nutrients and keep nutrients effective for a long time; In addition, biochar is converted from waste organic matter, which can turn waste into treasure and reduce environmental pollution. Modern planting methods use a lot of chemical fertilizers and polymer pesticides, the soil is increasingly hardened, polymer pesticides are difficult to decompose in the natural state, and heavy metals and other substances in the environment stay in the soil for a long time, resulting in soil water retention, fertility, and planting safety. and other attr...
