Embodiment 1
[0045] The formula composition of the biochar-based organic fertilizer provided in this example is as follows (by weight): 50% of biochar, 45% of urea, 4.9% of sodium carboxymethylcellulose, and 0.1% of thiamethoxam.
[0046] The preparation method is as follows:
[0047] After the biochar and urea are pulverized evenly, pass through a 40-mesh sieve; then weigh the raw materials according to the above ratio, add them to the mixer, and mix them evenly to obtain a mixed material; then add water to the mixed material until the water and the mixed material The mass ratio is 0.3:1, and after stirring evenly, the water-containing material is obtained; the water-containing material is sent to the granulator for granulation, and the granulated fertilizer is sent to the dryer, and dried at 60°C for 24 hours to obtain the above-mentioned Biochar-based organic fertilizer.
[0048] In this example, the preparation method of biochar is as follows: fill bagasse into a porcelain crucible, s...
