High-activity seaweed fertilizer specially used for peanut and preparation method thereof

Abstract

The invention discloses a high-activity seaweed fertilizer specially used for peanuts and a preparation method thereof and belongs to the technical field of production of crop specially-used fertilizers. The high-activity seaweed fertilizer is prepared from following raw materials comprising: urea, monoammonium phosphate, a calcium magnesium phosphate fertilizer, potassium sulfate, borax, EDTA chelating iron, EDTA chelating manganese, EDTA chelating zinc, ammonium heptamolybdate, a seaweed extraction liquid and seaweed residues. Compared with a fertilizer in the prior art, the high-activity seaweed fertilizer specially used for the peanuts is reasonable in formula, is complete in nutrition, can achieve an effect of increasing yield of the peanuts and improving quality of the peanuts.

Description

Technical field

[0001] The present invention is a specialty field of cropy fertilizer production technology, and specially involves a special high -active seaweed fertilizer and its preparation methods. Background technique

[0002] The peanuts were introduced to our country in the 16th century. They were one of the four major oil crops in my country. Among my country's crops, the area and total output value of peanuts were ranked seventh and fifth respectively.The planting area of Chinese peanuts is second only to rapeseed, with a planting area of about 5 million hectares and a total output of about 14 million tons, accounting for more than 40%of the world's total peanut production.Consumer countries and exporters.

[0003] my country's peanut production is widely produced, except for Tibet, Qinghai, Ningxia, Hong Kong and other provinces.It is mainly concentrated in the northern North China Plain, the coast of the Bohai Bay and the southern South China coastal area and the Sich...

Examples

Embodiment 1

[0045] Raw material ratio: 360 parts of urea, 145 parts of monoammonium phosphate, and 300 parts of potassium sulfate.

[0046] The specific production process is as follows:

[0047] 1. Measure urea, monoammonium phosphate, and potassium sulfate according to the ratio and then fully stir and mix them in the stirring pot;

[0048] 2. After the above materials are mixed evenly, they are conveyed into the granulator by a belt. A nozzle is installed in front of the granulator to spray steam to make the materials into balls and granulate. The granulation temperature is controlled at 40°C-50°C;

[0049] 3. The preliminary pelletized material enters the first drying drum and the first cooling drum in turn, and the temperature of the first drying outlet is controlled at 60°C-70°C;

[0050] 4. After the first cooling drum is discharged, the material is screened, and the large particles screened out are crushed and put into the granulator for granulation; the semi-finished products ob...

Embodiment 2

[0054] Raw material ratio: 365 parts of urea, 120 parts of monoammonium phosphate, 65 parts of calcium magnesium phosphate fertilizer, 300 parts of potassium sulfate, 15 parts of borax, 8 parts of EDTA chelated iron, 6 parts of EDTA chelated manganese, 7 parts of EDTA chelated zinc, 1 part of ammonium heptamolybdate.

[0055] Concrete production technology is with embodiment 1.

[0056] The obtained product has the specifications of 18-7-15, contains medium and trace elements, and does not contain seaweed extract and seaweed residue.

Embodiment 3

[0058] Raw material ratio: 365 parts of urea, 120 parts of monoammonium phosphate, 65 parts of calcium magnesium phosphate fertilizer, 300 parts of potassium sulfate, 15 parts of borax, 8 parts of EDTA chelated iron, 6 parts of EDTA chelated manganese, 7 parts of EDTA chelated zinc, 1 part of ammonium heptamolybdate, 10 parts of seaweed extract (note: 50 parts of liquid, namely 10 parts of dry basis).

[0059] Concrete production process is the same as embodiment 1 except step 2.

[0060] Step 2: After the above materials are mixed evenly, they are conveyed into the granulator by a belt. Two nozzles are installed at the front of the granulator, one of which sprays a certain amount of seaweed extract calculated according to the proportion, and the other nozzle sprays steam to make the material into a granulator. Ball granulation, the granulation temperature is controlled at 40°C-50°C.
