Embodiment 1

[0016] 1 kg of long-acting agent, 25 kg of monoammonium phosphate, 20 kg of potassium chloride, 25 kg of superphosphate, 3 kg of multi-element micro-fertilizer, 4 kg of bentonite, stir evenly, carry out compound fertilizer granulation, and then add 75 kg of large grain potassium chloride kg, 95 kg of diammonium phosphate, 240 kg of large urea and stir evenly to obtain a special fertilizer for deep application of corn;

[0017] The long-acting agent is prepared by mixing the following components evenly: 5 kg of humic acid, 5 kg of dicyandiamide, and 2 kg of cyanoquinone.

[0018] The product of the present invention is applied with 35 kilograms per mu, compared with 10 kilograms of diammonium phosphate per mu, 10 kilograms of potassium chloride, and 30 kilograms of topdressing urea. The corn yield of the product of the invention is 601.2 kg, which is 11% higher than that of the control and saves 30% of fertilizer.

Embodiment 2

[0020] 1.5 kg of long-acting agent, 27.5 kg of monoammonium phosphate, 22.5 kg of potassium chloride, 27.5 kg of superphosphate, 4 kg of multi-element micro-fertilizer, 4.5 kg of bentonite, stir evenly, carry out compound fertilizer granulation, and then add 77.5 kg of large grain potassium chloride kg, 97.5 kg of diammonium phosphate, 245 kg of large grain urea and stir evenly to obtain a special fertilizer for deep application of corn;

[0021] The long-acting agent is uniformly mixed with the following components: 7.5 kg of humic acid, 7.5 kg of dicyandiamide, and 4 kg of cyanoquinone.

[0022] The product of the present invention is applied with 35 kilograms per mu, compared with 10 kilograms of diammonium phosphate per mu, 10 kilograms of potassium chloride, and 30 kilograms of topdressing urea. The corn yield of the product of the invention is 632.4 kg, which is 16.76% higher than that of the control and saves 30% of fertilizer.

Embodiment 3

[0024] 2 kg of long-acting agent, 30 kg of monoammonium phosphate, 25 kg of potassium chloride, 30 kg of superphosphate, 5 kg of multi-element micro-fertilizer, 5 kg of bentonite, stir evenly, carry out compound fertilizer granulation, and then add 80 kg of large grain potassium chloride kg, 100 kg of diammonium phosphate, 250 kg of large grain urea and stir evenly to obtain a special fertilizer for deep application of corn;

[0025] The long-acting agent is made by mixing the following components evenly: 10 kg of humic acid, 10 kg of dicyandiamide, and 6 kg of cyanoquinone.

[0026] The product of the present invention is applied with 35 kilograms per mu, compared with 10 kilograms of diammonium phosphate per mu, 10 kilograms of potassium chloride, and 30 kilograms of topdressing urea. The corn yield of the product of the invention is 621.9 kg, which is 14.83% higher than that of the control and saves 30% of fertilizer.

Abstract

The invention relates to a special fertilizer for corn, which in detail is a mixed one-time deep dressing special fertilizer for corn. It comprises following steps: (1) preparing long effective agent, mixing humic acid 5-10 kg, dicyandiamide 5-10 kg, cyanide chinone 2-6 kg; (2) mixing long effective agent 1-2 kg, ammonium diacid phosphate 25-30kg, potassium chloride 20-25kg, single superphosphate 25-30kg, multiple microelement 3-5kg, bentonite 4-5 kg, preparing compound fertilizer; (3) adding large potassium chloride 75-80kg,diammonium phosphate 95-100kg, urea with large particle 240-250kg into said compound fertilizer, stirring evenly and getting deep-dressing special fertilizer for corn. The invention is characterized by good effect, increased fertilizer utilization rate, longer fertilizer efficiency, ability to increase quantity and benefit.

Description

technical field [0001] The invention relates to a special fertilizer for corn, in particular to a blended special fertilizer for one-time deep application of corn and a production method thereof. Background technique [0002] Corn is one of the important crops in my country's agriculture. It is mainly distributed in Northeast, Northwest and North China. Due to regional differences, its planting methods are also different. Traditional corn cultivation generally undergoes two shovels, two trips, one topdressing and other management measures during the growth period. This cultivation method is heavy and labor-intensive, and cannot adapt to the pace of agricultural modernization. In the fertilizer industry, corn special fertilizer is one of the more common special fertilizers. It is composed of nitrogen, phosphorus, potassium and trace elements. After this special fertilizer is applied to the soil, the above-mentioned process must be performed. Its utilization The yield is not ...
