Example Embodiment
[0063] Example 1:
[0064] 540 parts of urea are melted at a high temperature of about 135°C, enter the buffer tank, pressurized by the transfer pump, and pumped into the mixer at the top of the tower;
[0065] Combine 140 parts of potassium dihydrogen phosphate, 210 parts of potassium chloride, 100 parts of monoammonium phosphate, 50 parts of calcium-magnesium phosphate fertilizer, 26.5 parts of ferrous sulfate, 10 parts of zinc sulfate, 10 parts of EDTA chelated manganese, 10 parts of borax, 0.5 parts Ammonium molybdate and 3 parts of nano-carbon are weighed and sent to the mixer for full mixing; the mixed raw materials are crushed and sieved, then sent to the mixing heater to be heated to about 90°C; sent to the top of the tower with a bucket elevator Silo.
[0066] The hot mixed material in the top silo is uniformly measured by screw weighing and then sent to the above mixer, mixed with a high-speed shear mixer to form a thin paste material, the temperature is controlled at abou...
Example Embodiment
[0068] Example 2:
[0069] Take 500 parts of urea, 140 parts of potassium dihydrogen phosphate, 100 parts of monoammonium phosphate, 250 parts of potassium chloride, 50 parts of calcium magnesium phosphate fertilizer, 26.5 parts of ferrous sulfate, 10 parts of zinc sulfate, 10 parts of EDTA chelated manganese, and 10 parts of borax. Parts, 0.5 parts of ammonium molybdate, 3 parts of nano carbon;
[0070] The specific production process is the same as in Example 1.
[0071] The obtained high-concentration nano-carbon cotton special fertilizer has a nitrogen-phosphorus-potassium ratio of 23-8-20, and contains nano-carbon and medium and trace elements.
Example Embodiment
[0072] Example 3:
[0073] Take 540 parts of urea, 300 parts of potassium chloride, 60 parts of potassium dihydrogen phosphate, and 100 parts of monoammonium phosphate; the specific production process is the same as in Example 1.
[0074] The obtained product has a ratio of nitrogen, phosphorus and potassium of 26-8-20, and does not contain nano-carbon and medium and trace elements.
[0075] Comparative proportion: 54% ordinary potassium chloride compound fertilizer, the ratio of nitrogen, phosphorus and potassium is 18-18-18, it is Sanan compound fertilizer produced by Stanley Fertilizer Co., Ltd.
[0076] Xinjiang is my country’s largest high-quality cotton production base. The “National Cotton Engineering Technology Research Center” was established in Xinjiang in 1998 with the approval of the Ministry of Science and Technology. The applicant signed a strategic cooperation agreement with the National Cotton Engineering Technology Research Center in 2008. Therefore, the company The ex...
