Embodiment 1
[0049] The radix radix radiata husk was anaerobically cracked at 450°C for 2.5 hours, crushed and passed through a 200-mesh sieve, and the prepared biochar was mixed with the microbial agent at a weight ratio of 20:1. This is the first mixture;
[0050] Mix urea, monoammonium phosphate, potassium chloride, and limestone powder in a weight ratio of 36:10:20:13.8 and then perform disc granulation. During the granulation process, evenly spray silicon with an appropriate concentration of 0.2% of the total weight. Sodium acid solution.
[0051] Add 1.2% fulvic acid to the above-mentioned disc with a granulation rate of 80% to continue granulation.
[0052] After the above-mentioned humic acid is evenly wrapped, add the first mixture accounting for 15% of the total weight and attapulgite powder accounting for 5% of the total weight, continue to granulate, spray 0.2% sodium silicate solution evenly during the granulation process, and dry it to obtain The carbon-based fertilizer of ...
Embodiment 2
[0057] The radix radix radiata husk was anaerobically cracked at 450°C for 2.5 hours, crushed and passed through a 200-mesh sieve, and the prepared biochar was mixed with the microbial agent at a weight ratio of 16:1. This is the first mixture.
[0058] Mix urea, monoammonium phosphate, potassium sulfate, and limestone powder in a weight ratio of 32:9:20:13.5 and then perform disc granulation. During the granulation process, an appropriate amount of sodium silicate solution with a concentration of 0.2% is evenly sprayed.
[0059] 1.5% fulvic acid is added in the disc of above-mentioned granulation rate 80%, continue granulation.
[0060] After the above-mentioned humic acid is uniformly included, add 18% of the first mixture and 5% attapulgite powder, continue granulation, spray 0.2% sodium silicate solution evenly in the granulation process, and obtain the carbon-based fertilizer of the present invention after drying .
[0061] The fertilizer has a pH of 7.5, a particle siz...
Embodiment 3
[0064] The radix radix radiata shell was anaerobically cracked at 400°C for 3 hours, crushed and passed through a 200-mesh sieve, and the prepared biochar was mixed with the microbial agent at a weight ratio of 22:1. This is the first mixture.
[0065] Mix urea, diammonium phosphate, potassium sulfate, and limestone powder in a weight ratio of 35:12:20:8.4, then perform disk granulation, and spray 0.2% sodium silicate solution evenly during the granulation process.
[0066] Add 1.0% fulvic acid into the above disc with 80% granulation rate, and continue granulation.
[0067] After the above-mentioned humic acid is uniformly contained, add 17% of the first mixture and 5.6% attapulgite powder, continue to granulate, evenly spray an appropriate amount of sodium silicate solution with a concentration of 0.2% in the granulation process, and obtain the present invention after drying. Charcoal-based fertilizers.
