preparation example Construction

[0027] The preparation method of the above-mentioned amino acid-containing high-phosphorus multifunctional suspension liquid fertilizer comprises the following steps:

[0028] (1) Potassium pyrophosphate, boric acid, zinc nitrate, proline, glucose, urea ammonium nitrate, ammonium polyphosphate, EDTA-Fe, suspending agent, humectant and plant extract are weighed respectively by weight and number ratio;

[0029] (2) In the reactor, add the plant extract earlier,

[0030] (3) Heat to 50-60°C, add potassium pyrophosphate, boric acid, zinc nitrate, stir to dissolve;

[0031] (4) After cooling, add proline and glucose and stir until completely dissolved;

[0032] (5) Then add urea ammonium nitrate and ammonium polyphosphate and stir until the solution is clear;

[0033] (6) Finally, add EDTA-Fe, humectant, and suspending agent, stir evenly and set the volume to obtain a high-phosphorus multifunctional suspension liquid fertilizer containing amino acids.

Embodiment 1

[0035] The preparation method of the high-phosphorus multifunctional suspension type liquid fertilizer 1 containing amino acid comprises the following steps:

[0036] 1) Take by weighing 100 parts of potassium pyrophosphate, 5 parts of boric acid, 5 parts of zinc nitrate, 50 parts of proline, 50 parts of glucose, 130 parts of urea ammonium nitrate, 300 parts of Ammonium polyphosphate with a degree of polymerization of 5-18, 100 parts of EDTA-Fe, 20 parts of suspending agent, 20 parts of humectant and 300 parts of tea extract, the preparation method of tea extract: mix every 100 grams of tea The dry sample is boiled in 1L of boiling water at 100°C for 15 minutes, and then prepared after cooling to obtain a tea extract, wherein the content of the extract in the tea extract is 50-70%.

[0037] (2) In the reactor, add tea extract earlier,

[0038] (3) Heat to 50-60°C, add potassium pyrophosphate, boric acid, zinc nitrate, stir to dissolve;

[0039] (4) After cooling, add proline...

Embodiment 2

[0048] The fertilizer preparation method of the present embodiment is basically the same as that of Example 1, except that the formula content is different:

[0049] The formula of high-phosphorus multifunctional suspension liquid fertilizer 2 containing amino acid is: 120 parts of potassium pyrophosphate, 4 parts of boric acid, 6 parts of zinc nitrate, 60 parts of proline, 40 parts of glucose, 100 parts of urea nitrate Ammonium, 330 parts of ammonium polyphosphate with a polymerization degree of 5 to 18, 110 parts of EDTA-Fe, 15 parts of suspending agent, 25 parts of humectant and 400 parts of tea extract, the preparation method of tea extract: mix each 100 grams of dried tea leaves are boiled in 1 L of boiling water at 100° C. for 15 minutes, and then prepared after cooling to obtain a tea extract, wherein the content of the extract in the tea extract is 50-70%.

Abstract

The invention discloses a high-phosphorus multifunctional suspended liquid fertilizer containing amino acid and a preparation method of the liquid fertilizer. The high-phosphorus multifunctional suspended liquid fertilizer comprises, by weight, 90-110 parts of potassium permanganate, 4-6 parts of boric acid, 4-6 parts of zinc nitrate, 45-55 parts of proline, 125-135 parts of urea ammonium nitrate,290-310 parts of ammonium polyphosphate, 90-110 parts of EDTA-Fe, 18-22 parts of suspending agents, 18-22 parts of humectants and 300-400 parts of plant extracts. The high-phosphorus multifunctionalsuspended liquid fertilizer is simple in production process, high in nutrient content, comprehensive in nutrition, easily absorbed by crops, rapid in effect, safe to use, stable in effect, free from toxic and side effects, and the requirements of the crops for different nutrients in different growth periods can be met. Crop yield is increased, quality is improved, and the fertilizer is not easilyprecipitated or crystallized in long-term storage, good in suspension property and low in storage and transportation cost.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an amino acid-containing high-phosphorus multifunctional suspension liquid fertilizer and a preparation method thereof. Background technique [0002] With the development of modern facility agriculture technology, water and fertilizer integration technology is developing rapidly in our country. The requirement of this technology is to apply the fertilizer after dissolving it in water, so fertilizers with better water solubility are popularized very quickly. In recent years, the mainstream of water-soluble fertilizers in my country is the clear liquid type, which has low nutrient content and is not easy to transport. The suspension-type liquid fertilizer suspends the nutrient particles in the liquid dispersion system by adding a suspension aid, which improves the nutrient content of the water-soluble fertilizer, and has the advantages of easy transportation and good solubilit...
