Problems solved by technology

[0006] 1. Long-term use will cause the soil to become compacted, the soil fertility will be weakened, the aggregate structure of the soil will be seriously damaged, and the ecological environment will be seriously damaged.
[0007] 2. The nutrients in the fertilizer are not uniform, the fertilizer period is short, and the law of nutrient release cannot match the law of corn nutrient absorption. Topdressing is required, resulting in a waste of labor
[0008] 3. The utilization rate of fertilizer is low, which easily causes the fixation and loss of nutrients, which not only wastes resources, but also easily pollutes the environment
[0009] 4. The nutrition is not comprehensive, and generally does not contain boron, silicon, and zinc elements that can significantly improve the yield and quality of corn, resulting in low yield or reduced quality of corn

Embodiment 1

[0060] Example 1: Preparation of special fertilizer for corn

[0061] 539 parts of urea, 258 parts of potassium chloride (62%), 195 parts of monoammonium phosphate, and 8 parts of fertilizer synergist NAM.

[0062] Step 1: Melt 539 parts of urea at a high temperature of 130°C-140°C, enter the buffer tank, pressurize it through the delivery pump, and pump it into the overhead mixer;

[0063] Step 2: Put 258 parts of potassium chloride, 195 parts of monoammonium phosphate, and 8 parts of fertilizer synergist into the mixer after metering and mix well. After the mixed raw materials are crushed and screened, they are sent to the mixing heater for heating to 85-100°C. Send it to the tower top silo with a bucket elevator;

[0064] Step 3: Send the hot mixture in the tower top silo in step 2 into the mixer described in the above step 1 after being uniformly measured by a spiral metering scale, and mix it with a high-speed shear mixer to make a thin paste material, and the temperat...

Embodiment 2

[0066] Example 2: Preparation of special fertilizer for corn

[0067] 530 parts of urea, 240 parts of potassium chloride (62%), 180 parts of monoammonium phosphate, 5 parts of sodium octaborate tetrahydrate, 35 parts of sodium silicate, and 10 parts of chelated zinc with EDTA.

[0068] The specific implementation steps are the same as the implementation example 1.

[0069] The product specification of the special fertilizer for corn obtained is 26-10-15, does not contain fertilizer synergist NAM, and contains boron, zinc and silicon elements.

Embodiment 3

[0070] Example 3: Preparation of special fertilizer for corn

[0071] 520 parts of urea, 242 parts of potassium chloride (62%), 180 parts of monoammonium phosphate, 8 parts of fertilizer synergist NAM, 5 parts of sodium octaborate tetrahydrate, 35 parts of sodium silicate, 10 parts of chelated zinc with EDTA.

[0072] The specific implementation steps are the same as the implementation example 1.

[0073] The product specification of the special fertilizer for corn obtained is 26-10-15, containing fertilizer synergist NAM and elements of boron, zinc and silicon.

Abstract

The invention discloses a high-efficiency all-nutritional corn special fertilizer prepared by the granulation of a tower-type melt and a production method thereof, and relates to the technical field of special fertilizers of crop formulas. The high-efficiency all-nutritional corn special fertilizer is prepared from 450 to 650 weight parts of urea, 150 to 300 weight parts of potassium chloride, 100 to 300 weight parts of monoammonium phosphate, 5 to 10 weight parts of fertilizer synergist, 2 to 40 weight parts of sodium silicate, 2 to 8 weight parts of sodium octaborate tetrahydrate and 2 to 12 weight parts of chelate zinc fertilizer which serve as raw materials through the granulation of the tower-type melt. The corn special fertilizer has the advantages of improving the yield and quality of corn, improving soil and soil fertility and reducing labor intensity along with comprehensive nutrition, high utilization rate and one-time fertilization.

Description

technical field [0001] The invention relates to the technical field of fertilizer specially formulated for crops, in particular to a special fertilizer for corn. Background technique [0002] Maize is an annual herbaceous plant of the grass family. It is an important food crop and feed source, and it is also the food crop with the highest total output in the world. Corn is the second largest grain crop after wheat in my country. The national corn planting area and output account for 26% of the grain planting area and 30% of the total grain output respectively. In my country, corn grain, economy and feed are used together, which has a huge impact on the development of the entire national economy. [0003] Maize needs to absorb various mineral nutrients from the soil, among which nitrogen is the most, potassium is the second, and phosphorus is the third. Generally, 2.5 kg of pure nitrogen, 1.2 kg of phosphorus pentoxide, and 2.0 kg of potassium oxide are absorbed from the so...
