Embodiment 1

[0042] Example 1: Preparation of nano-carbon silicon-containing special fertilizer for rice

[0043] The mass parts of raw material components are as follows: 407 parts of urea, 380 parts of potassium chloride (60% potassium oxide content), 160 parts of monoammonium phosphate, 3 parts of nano-carbon, and 50 parts of sodium silicate.

[0044] The production process is as follows:

[0045] 1. Melt urea at a high temperature of 135°C, enter the buffer tank, pressurize it through a delivery pump, and pump it into the top mixer;

[0046] 2. Put potassium chloride, monoammonium phosphate, sodium silicate, and nano-carbon into the agitator to mix well, and after crushing and screening, send it to the mixing heater to heat to 90°C, and send it to the mixer with a bucket elevator. To the tower top silo;

[0047] 3. Put the hot mixture in the tower top silo in step 2 into the mixer described in the above step 1 after being evenly measured by a spiral meter, and mix it with a high-sp...

Embodiment 2

[0049] Example 2: Preparation of nano-carbon silicon-containing special fertilizer for rice

[0050] The mass parts of raw material components are as follows: 460 parts of urea, 327 parts of potassium chloride (62% potassium oxide content), 160 parts of monoammonium phosphate, 3 parts of nano-carbon, and 50 parts of sodium silicate.

[0051] The production process is the same as implementation example 1.

[0052] The obtained product contains nano-carbon and silicon elements, and the contents of nitrogen, phosphorus pentoxide and potassium oxide are respectively 23%, 8% and 20%, all of which are percentages by mass.

Embodiment 3

[0053] Example 3: Preparation of nano-carbon silicon-containing special fertilizer for rice

[0054] The raw material components are as follows: 457 parts of urea, 290 parts of potassium chloride (62% potassium oxide content), 200 parts of monoammonium phosphate, 3 parts of nano-carbon, and 50 parts of sodium silicate.

[0055] The production process is the same as implementation example 1.

[0056] The obtained product contains nano-carbon and silicon elements, and the contents of nitrogen, phosphorus pentoxide and potassium oxide are respectively 23%, 10% and 18%, all of which are percentages by mass.

Abstract

The invention discloses a nano-carbon silicon-containing rice special fertilizer and a production method thereof, and relates to the technical field of crop formula special fertilizers. It uses 400-500 parts of urea, 260-400 parts of potassium chloride, 100-220 parts of monoammonium phosphate, 1-5 parts of nano-carbon, and 1-50 parts of sodium silicate as raw materials. Sub-heating, mixing and stirring, spray granulation, cooling, sieving, measuring and packaging. The invention has unique production technology, energy saving and consumption reduction, and the special fertilizer of the invention has comprehensive nutrients, balanced fertilizer, high fertilizer utilization rate and less environmental pollution.

Description

technical field [0001] The invention relates to the technical field of special fertilizer for crops, in particular to a nano-carbon silicon-containing special fertilizer for rice and a production method thereof. Background technique [0002] Rice is the main food crop in my country. The population of the country who eats rice as a staple food accounts for about 50% of the total population. Since the founding of the People's Republic of China more than half a century ago, the rice planting area in my country has accounted for 26.6% of the grain sown area on average, and the total output of rice has accounted for 26.6% of the total grain. 43.6% of the output, accounting for more than half of the country's commercial grain. Therefore, rice production plays an extremely important role in my country's national economy. [0003] As a typical silicon-loving crop, rice is known as "silicate plant". The application of silicon fertilizer can make rice resistant to insects, diseases,...
