Embodiment 1

[0064] Melt 540 parts of urea at a high temperature of about 135°C, enter the buffer tank, pressurize it through a delivery pump, and pump it into the top mixer;

[0065] 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, after metering, are sent to the mixer and mixed evenly; after the mixed raw materials are crushed and screened, they are sent to the mixing heater to be heated to about 90°C; they are sent to the top of the tower by a bucket elevator Silo.

[0066] The hot mixture in the silo at the top of the tower is evenly measured by the spiral meter, and then sent to the above mixer, mixed by a high-speed shear mixer to make a thin paste material, the temperature is controlled at about 110 ...

Embodiment 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 manganese chelated with EDTA, and 10 parts of borax 0.5 part, 0.5 part of ammonium molybdate, 3 parts of nano carbon;

[0070] Concrete production technology is with embodiment 1.

[0071] The obtained special fertilizer for high-concentration nano-carbon cotton has a ratio of nitrogen, phosphorus and potassium of 23-8-20, and contains nano-carbon and medium and trace elements.

Embodiment 3

[0073] Get 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 example: 54% ordinary potassium chloride compound fertilizer, the ratio of nitrogen, phosphorus and potassium is 18-18-18, and it is Sanan compound fertilizer produced by Stanley Fertilizer Co., Ltd.

[0076] Xinjiang is the largest high-quality cotton production base in my country. The "National Cotton Engineering Technology Research Center" was established in Xinjiang with the approval of the Ministry of Science and Technology in 1998. The applicant signed a strategic cooperation agreement with the National Cotton Engineering Technology Research Center in 2008. Therefore, the company The experimen...

Abstract

The invention discloses high-concentration nano-carbon cotton special fertilizer and a preparation method thereof, and belongs to the technical field of fertilizer. The high-concentration nano-carbon cotton special fertilizer obeys a cotton nutrient absorption rule and is prepared form raw materials of urea, potassium dihydrogen phosphate, potassium chloride, calcium-magnesium-phosphate fertilizer, monoammonium phosphate, ferrous sulphate, zinc sulfate, ethylene diamine tetraacetic acid (EDTA)-manganese chelate, borax, ammonium molybdate and nano-carbon according to certain ratios. The preparation method comprises the following steps of melting urea at a high temperature, carrying out pressurization, mixing the melted urea and other raw materials well, carrying out crushing and sieving, heating, preparing paste, carrying out vibration filtration, carrying out sprinkling and forming, cooling, sieving, carrying out anti-caking treatment and carrying out packaging. The high-concentration nano-carbon cotton special fertilizer has comprehensive nutrition, balanced fertilizer components and a high fertilizer utilization rate, and can improve a cotton yield and cotton quality.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a high-concentration nano-carbon special fertilizer for cotton and a preparation method thereof. Background technique [0002] Cotton is native to tropical and subtropical regions and is a perennial short-day crop. After long-term artificial selection and cultivation, it gradually moved north to the temperate zone and evolved into an annual crop. The growth period is divided into five stages: sowing stage, seedling stage, bud stage, flowering boll stage and boll opening stage. Cotton is not only a necessity of people's life, but also an important industrial raw material and military material, and plays an important role in the development of the national economy. [0003] Studies have shown that for every 100 kilograms of lint produced, 10-18.5 kilograms of nitrogen and phosphorus (P 2 o 5 ) 3.5-6 kg, potassium (K 2 O) 13 to 16.5 kg, absorbing nitrogen, phosphorus, and po...
