Problems solved by technology

[0004] It can be found that the preparations used in the prior art for treating fertilizers with nitrification inhibitors all have defects: the use of DMP is mainly limited to the application of its phosphate form, that is, it mainly exists in the form of DMPP; the application of liquid preparations is mainly concentrated on its Composition with mineral fertilizers, there are certain limitations

Embodiment 1

[0022] Embodiment 1 liquid formula

[0023] Add 3,4-dimethylpyrazole and solvent into the reaction kettle, slowly add acid while stirring, and mix well to obtain a liquid solution. The liquid formulas A-G are shown in Table 1, and H is the comparison group:

[0025]

[0026]

Embodiment 2

[0027] Clarity test under embodiment 2 normal temperature conditions

[0028] The liquid formulations A-G in Example 1 were stored under sealed conditions at 25 degrees for 1 week, 2 weeks, 4 weeks, 2 months and 3 months, and the properties of the samples were visually studied.

[0029] The observation results showed that the liquid formulations A-G were clear solutions without solid crystals or solid precipitation during different storage periods.

Embodiment 3

[0030] The stability test of embodiment 3 liquid formulations

[0031] After the liquid formula A-G of Example 1 and the comparison group H were treated at 170 degrees for 5 minutes, the content of 3,4-dimethylpyrazole was detected by HPLC to understand its stability at high temperature, the specific data See Table 2 below.

Abstract

The invention discloses a liquid formula composition which comprises 3, 4-dimethylpyrazole, organic acid or inorganic acid and a solvent. The mass ratio of the 3, 4-dimethylpyrazole to the organic acid or the inorganic acid is 1: (0.5-5), and the mass ratio of the 3, 4-dimethylpyrazole to the solvent is 1: (0.5-50). The invention also discloses an application of the liquid formula composition in fertilizer production. The liquid formula composition containing 3, 4-dimethylpyrazole as a nitrification inhibitor has the advantages of high stability, good compounding property and low loss rate. The liquid formula composition can be used for producing a simple substance fertilizer or a compound fertilizer in the processes of tower granulation, drum granulation, drum granulation, extrusion granulation and the like in an internal adding or external spraying manner, the loss rate of effective components in the production process is low, and the produced stable fertilizer is not easy to harden and long in effective storage time.

Description

technical field [0001] The invention relates to the technical field of nitrification inhibitor compositions, in particular to a liquid formulation composition and its application. Background technique [0002] Nitrogen is an essential nutrient element for plant growth, and agricultural production cannot do without a large amount of nitrogen fertilizer. The ammonium nitrogen applied to the soil or the ammonium nitrogen produced by the hydrolysis of urea will be converted into more mobile nitrate nitrogen under the action of nitrifying bacteria, resulting in nitrate leaching loss, which reduces the utilization rate of nitrogen fertilizer and brings nitrogen oxides and other greenhouse gas emissions and groundwater pollution. As a countermeasure, nitrification inhibitors can usually be added to fertilizers or soil to inhibit nitrification in the soil and reduce the source of nitrate nitrogen. Such nitrification inhibitors include biological nitrification inhibitors (BNI), suc...
