[0003] At present, the preparation methods of biochar fertilizers disclosed by the State Intellectual Property Office of the People's Republic of China mostly take biomass without high-temperature carbonization as raw materials to prepare fertilizers, such as "A Production Method of Biochar Fertilizers" (published No. CN 103274778A), "A Wheat Straw Biochar Fertilizer for Promoting Root Growth and Its Preparation Method" (Publication No. CN105085020A), and there are few reports on the preparation method of carbonized raw materials, especially after carbonization of banana pseudostem as biomass The method for preparing fertilizer has not been reported

Embodiment Construction
[0031] Below by embodiment the content of the present invention is specifically described:
[0032] A preparation method of banana pseudostem charcoal-based biological fertilizer, comprising:
[0033] 1) Take a fresh sample of the banana pseudostem, peel off all the leaves on the pseudostem, crush it, and let it dry naturally for a day, then put it in the muffle furnace, and let nitrogen gas flow in for 10 minutes. 400°C, constant temperature and nitrogen flow for 4 hours, take it out, grind the carbonized product into powder, and pass through a 200-mesh sieve to obtain banana pseudostem biochar; in this step, increase nitrogen to exclude oxygen to ensure carbonization in a strict anaerobic environment Carry out, guarantee the quality of the banana pseudostem biochar that obtains;
[0034] 2) Grinding urea, superphosphate and potassium sulfate into powder respectively, then mixing the three evenly according to the mass ratio of urea, superphosphate and potassium sulfate of 1:...

Abstract
The invention discloses a banana pesudostem charcoal-based bio-fertilizer as well as a preparation method and application thereof. The banana pesudostem charcoal-based bio-fertilizer is prepared by a series of processes including high-temperature charring, proportioning, granulation, drying and the like. The bio-fertilizer is of uniform granules, has sufficient fertility and balanced elements, and has the effects of significantly improving the pH value of acid soil in south China and obviously improving the growth vigor of banana seedlings; and the process route is clear, the preparation method is simple and convenient, and the bio-fertilizer has good market application value.
Description
technical field [0001] The invention belongs to the technical field of biochar fertilizers, and in particular relates to a banana pseudostem charcoal-based biofertilizer and a preparation method and application thereof. Background technique [0002] Biochar is a kind of insoluble and stable biochar formed by pyrolysis under high-temperature anaerobic environment, which uses agricultural production waste, wood and its leftovers, rich in biomass sludge, vegetation leaves, livestock manure and other biomass as raw materials. , highly aromatized, carbon-rich solid matter. Biochar is rich in carbon elements up to 60%, in addition to rich in H, O, N, S, C, soluble K, Ca, Na, Mg and other elements. The rich pore structure of biochar makes biochar have larger porosity and specific surface area, strong ability to absorb water and air, and small bulk density, which can effectively increase soil pH and improve acidic soil texture; at the same time, biochar can significantly reduce So...
