Embodiment 1

[0026] A compound ammonium fertilizer has the following components, all in parts by weight:

[0027] 40 parts of ammonium sulfate, 40 parts of humic acid, 10 parts of potassium fulvic acid, 7 parts of urea, 2.5 parts of clay, and 0.5 parts of diethyl ethyl.

[0028] After stirring and mixing the above-mentioned raw materials in parts by weight, they are granulated and formed by 100,000-ton compound fertilizer equipment produced by Shandong Xinruite Machinery Manufacturing Co., Ltd. to obtain a compound ammonium fertilizer.

[0029] The application method of compound ammonium fertilizer is shown in the table below:

[0030] Applied crops

Application amount and application method

wheat

Base fertilizer: 15kg / mu; topdressing: 10kg / mu each time, topdressing once

[0031] corn

Base fertilizer: 25kg / mu; topdressing: 15kg / mu each time, topdressing once

Peach

Base fertilizer: 2kg / tree; topdressing: 2kg / tree each time, topdressing ...

Embodiment 2

[0036] A compound ammonium fertilizer has the following components, all in parts by weight:

[0037] 42 parts of ammonium sulfate, 42 parts of humic acid, 8 parts of potassium fulvic acid, 5 parts of urea, 2.5 parts of clay, and 0.8 parts of diethyl hexanoate.

[0038] After stirring and mixing the above-mentioned raw materials in parts by weight, they are granulated and formed by 100,000-ton compound fertilizer equipment produced by Shandong Xinruite Machinery Manufacturing Co., Ltd. to obtain a compound ammonium fertilizer.

[0039] Compound ammonium fertilizer application method is as embodiment 1.

Abstract

The invention relates to a compound ammonium fertilizer and a preparation method thereof, belonging to the technical field of compound fertilizers. The compound ammonium fertilizer comprises the following components in parts by weight: 35-45 parts of ammonium sulfate, 35-45 parts of humic acid, 5-15 parts of potassium fulvate, 5-10 parts of urea, 2-5 parts of clay and 0.2-1 part of diethyl aminoethyl hexanoate. The compound ammonium fertilizer is instantly dissolved, has no residue, and can be easily absorbed by crops. The compound ammonium is applied to soil and can be directly absorbed by the crops with no need of decomposition and transformation, and the fertilizer effect is rapidly taken.

Description

technical field [0001] The invention relates to a compound ammonium fertilizer and a preparation method thereof, belonging to the technical field of compound fertilizers. Background technique [0002] The effective utilization rate of chemical fertilizers in our country is only about 30%, and the effective utilization rate of nitrogen fertilizer is even less than 30%. Urea is a high-concentration nitrogen fertilizer. During its granulation process, a small amount of biuret will be produced, also known as biuret. Biuret has an inhibitory effect on crop absorption. The main topdressing nitrogen fertilizer in my country is urea, which leads to the effective use of nitrogen fertilizer. The rate is low. my country stipulates that the content of urea biuret for fertilizers should be less than 0.5%. When the biuret content exceeds 1%, it often causes soil salinization, poor air permeability, and crops are prone to flower and fruit drop, damage to crop root system, and affect growt...
