[0024] Example 1:
[0025] The nutrient for tobacco planting is obtained by the following preparation method:
[0026] ① Washing: Wash the discarded oyster shells with clean water to remove the sand and impurities on the surface of the oyster shells;
[0027] ②Drying: drying the oyster shell obtained in step ① and pulverizing it with a ball mill to obtain a coarse powder of 80 mesh oyster shell;
[0028] ③Cryogenic pulverization: The oyster shell coarse powder obtained in step ② is subjected to low-temperature freezing and low-temperature sublimation drying in sequence, and then using liquid nitrogen as the grinding medium, using an ultra-low temperature pulverizer at -80°C for low-temperature pulverization;
[0029] ④High-pressure micro-jet ultra-fine pulverization treatment, add the material obtained in step ③ to 5 times the weight of pure water and mix it evenly, treat it with a high-speed shear emulsifier for 10 minutes, and then use a high-pressure micro-jet ultra-fine pulverizatio...

[0030] Example 2:
[0031] The nutrient for tobacco planting is obtained by the following preparation method:
[0032] ① Washing: Wash the discarded oyster shells with clean water to remove the sand and impurities on the surface of the oyster shells;
[0033] ②Drying: drying the oyster shell obtained in step ① and pulverizing it with a ball mill to obtain a coarse powder of 100 mesh oyster shell;
[0034] ③Cryogenic pulverization: the oyster shell coarse powder obtained in step ② is subjected to low-temperature freezing and low-temperature sublimation drying at -10°C in sequence, and then liquid nitrogen is used as the grinding medium, and an ultra-low temperature pulverizer is used for low-temperature crushing at -100°C;
[0035] ④High-pressure micro-jet ultra-fine pulverization treatment, add the material obtained in step ③ into 6 times the weight of pure water to mix uniformly, treat it with a high-speed shear emulsifier for 5 minutes, and then use high-pressure micro-jet ultra-fine ...

[0036] Example 3:
[0037] The nutrient for tobacco planting is obtained by the following preparation method:
[0038] ① Washing: Wash the discarded oyster shells with clean water to remove the sand and impurities on the surface of the oyster shells;
[0039] ②Drying: drying the oyster shell obtained in step ① and pulverizing it with a ball mill to obtain a coarse powder of 100 mesh oyster shell;
[0040] ③Cryogenic crushing: the oyster shell coarse powder obtained in step ② is subjected to low-temperature freezing and low-temperature sublimation drying at -18°C in sequence, and then liquid nitrogen is used as the grinding medium, and an ultra-low temperature crusher is used for low-temperature crushing at -120°C;
[0041] ④High-pressure micro-jet ultra-fine pulverization treatment, add the material obtained in step ③ to 5 times the weight of pure water and mix it evenly, treat it with a high-speed shear emulsifier for 10 minutes, and then use a high-pressure micro-jet ultra-fine pulver...
