Embodiment 1

[0027] A drying-free fertilizer, comprising the following parts by mass: 20-40 parts by mass of urea; 5-10 parts by mass of solvent; 10-15 parts by mass of ammonium chloride; 5-15 parts by mass of common calcium; 10-15 parts by mass of potassium chloride Parts by mass; 10-20 parts by mass of ammonium dihydrogen phosphate; 10-20 parts by mass of bentonite; 5-15 parts by mass of dolomite; 0.5-1 parts by mass of trace element boron; 0.2-0.5 parts by mass of trace element iron; 5-10 parts by mass of acid; 0.3-0.5 parts by mass of trace element phosphorus; 5-10 parts by mass of desiccant.

[0028] Include the following steps:

[0029] S1: crush urea, ammonium chloride, general calcium, potassium chloride, ammonium dihydrogen phosphate, bentonite, dolomite, trace element boron, trace element iron, nitrohumic acid, trace element phosphorus, and desiccant in advance, Use a micro-crusher to crush it into particles whose particle size does not exceed 80 μm;

[0030] S2: Take a certain...

Embodiment 2

[0035] The solvent is water, and the general calcium includes calcium dihydrogen phosphate and gypsum, and wherein the proportion of calcium dihydrogen phosphate and gypsum is 1:2, and the bentonite includes montmorillonite, albite and quartz, wherein montmorillonite, The proportion of albite and quartz is 8:1:1, and the desiccant is modified magnesium oxide.

[0036] Include the following steps:

[0037] S1: crush urea, ammonium chloride, general calcium, potassium chloride, ammonium dihydrogen phosphate, bentonite, dolomite, trace element boron, trace element iron, nitro humic acid, trace element phosphorus, and desiccant in advance, Use a micro-crusher to crush it into particles whose particle size does not exceed 80 μm;

[0038] S2: Take a certain proportion of urea, ammonium chloride, general calcium, potassium chloride, ammonium dihydrogen phosphate, bentonite, dolomite, micro-nitro humic acid and add it into the solvent for stirring. During the stirring process, heatin...

Embodiment 3

[0043] The preparation method of modified magnesium oxide is divided into the following steps:

[0044] Step 1: crushing magnesium oxide, dispersing the crushed magnesium oxide particles in deionized water, stirring, and heating during the stirring process;

[0045] Step 2: Add ethanolamine solution during stirring and heating, continue stirring and heating after adding, and seal the container after adding ethanolamine solution and stirring;

[0046] Step 3: Take out the material, cool it, then filter and sieve the material, then dry the sieved material, and continue to perform secondary filtration after drying;

[0047] Step 4: Grinding the filtered modified magnesium oxide to obtain modified magnesium oxide particles with a diameter of 20-40 μm.

[0048] In this example, magnesium oxide is commonly known as bitter soil, also known as magnesium oxide. Magnesium oxide is an alkaline oxide, has the properties of an alkaline oxide, and belongs to gelling materials. It is a whit...

Abstract

The invention discloses a drying-free fertilizer and a preparation method thereof, and relates to the field of fertilizers. The drying-free fertilizer comprises the following components by mass: 20-40parts of urea; 5-10 parts by mass of a solvent; 10-15 parts by mass of ammonium chloride; 5-15 parts by mass of superphosphate; 10-15 parts by mass of potassium chloride; 10-20 parts by mass of ammonium dihydrogen phosphate; 10-20 parts by mass of bentonite; 5-15 parts by mass of dolomite; 0.5-1 part by mass of trace element boron; 0.2-0.5 part by mass of trace element iron; 5-10 parts by mass ofnitrohumic acid; 0.3-0.5 part by mass of trace element phosphorus; and 5-10 parts by mass of a drying agent. According to the invention, ammonium chloride, superphosphate, potassium chloride, ammonium dihydrogen phosphate, bentonite, dolomite, trace element boron, trace element iron, nitrohumic acid, trace element phosphorus and a drying agent are arranged, most of the added raw materials exceptthe desiccant have the characteristic of low hygroscopicity, the mixed raw materials have the effect of applying nutrition to the land, the fertilizer is easy to dry in the production process due to low hygroscopicity, and the fertilizer drying effect is better by matching with the added desiccant.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a drying-free fertilizer and a manufacturing method thereof. Background technique [0002] Fertilizer refers to a class of substances that provide one or more essential nutrient elements for plants, improve soil properties, and increase soil fertility levels. It is one of the material bases of agricultural production, mainly including ammonium phosphate fertilizers, water-soluble fertilizers with a large number of elements , Medium element fertilizers, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc. [0003] In order to improve the utilization rate and commodity sales value of granular fertilizers, in the traditional fertilizer granulation production, it needs to go through drying, cooling and other technological processes, and it is necessary to use coal or gas to provide heat sources and cooling devices, which increas...
