Embodiment 1
[0021] Embodiment 1: corn cob charcoal production method
[0022] Exemplarily, the method for producing corncob granular carbon using the simple corncob granular carbonization furnace described in the Chinese invention patent No. ZL200710086505.4 includes steps such as material selection, material processing, furnace charging, carbonization, cooling and discharging, and metering and packaging. , but not limited to this.
[0023] Material selection: Naturally air-dry the corncobs of agricultural by-products to reduce the water content to below 20%.
[0024] Material processing: use any crushing method in the prior art to process and crush the above-mentioned qualified corncobs, and the diameter of the crushed corncobs is 2-10mm. The crushed corn cob particles can be sieved, and the corn cob particles that do not meet the requirements can be reprocessed.
[0025] Furnace charging and carbonization: put the processed corncob particles into the furnace body, and the initial amou...
Embodiment 2
[0030] Embodiment 2: Carbon-based paddy rice seedling raising substrate formula production process
[0031] Follow the steps below to mix by weight ratio or weight percentage:
[0032] (1) Stir the biochar particles and peat evenly with a ZLC-300 mixer at a ratio of 10:7.
[0033] (2) Use wood vinegar to adjust the acidity to pH 4.5-5.5, and the dosage is about 0.15ml / g according to the weight percentage.
[0034] (3) Measurement and packaging.
Embodiment 3
[0035] Embodiment 3: Carbon-based paddy rice seedling raising substrate formulation production process
[0036] Follow the steps below to mix by weight ratio or weight percentage:
[0037] (1) Mix biochar particles, peat, and perlite in a ratio of 2:2:1.
[0038] (2) Mix (1) with diammonium phosphate, potassium dihydrogen phosphate, and zinc sulfate at a ratio of 95%, 3%, 1.5%, and 0.5%, and stir evenly with a ZLC-300 mixer.
[0039] (3) Use wood vinegar to adjust the acidity to pH 4.5-5.5, and the dosage is about 0.13ml / g according to the weight percentage.
[0040] (4) Measurement and packaging.
