Problems solved by technology

[0003] However, in actual production, the content of ordinary amino acids is low, the dosage is large, and it is easy to absorb moisture and agglomerate when placed for a long time. When dissolved in water, it often floats on the water surface to increase the difficulty of dissolution.
Amino acid waste liquid is mostly because the amino acid content is unstable, which is easy to affect product quality
[0004] At the same time, the relevant national policies, the plant regulators commonly used in fertilizers such as DA-6, gibberellin, sodium nitrophenolate and other products are classified as pesticide products, which limits the use of these plant growth hormones in fertilizers

Embodiment 1

[0031] A preparation method of liquid fertilizer, said method comprising the following steps:

[0032] Step 1, the dissolution of potassium dihydrogen phosphate

[0033] Add 100g of potassium dihydrogen phosphate and 20g of ammonia water into a 1L reaction kettle at the same time (how much is the amount added to the reaction kettle, and the order of addition, because the reaction of potassium dihydrogen phosphate and ammonia water is an exothermic reaction, to solve the problem of dissolving potassium dihydrogen phosphate slow problem), stirred at room temperature for 30min to dissolve, and adjusted the pH to 6 after the reaction.

[0034] Step 2, the addition of trace elements

[0035] Add 75g chelated zinc successively to the solution in step 1 and stir for 10min to dissolve completely;

[0036] Add 20g of titanium citrate and stir for 10min to dissolve completely;

[0037] Add 25g of chelated boron and stir for 30min until the resulting solution is clarified;

[0038] A...

Abstract

The invention relates to a liquid fertilizer preparation method, which comprises: dissolving potassium dihydrogen phosphate, sequentially adding trace elements, amino acids and glucose, and stirring.According to the present invention, the content of the compound amino acid in the prepared liquid fertilizer is more than or equal to 100 g / L, the content of potassium, phosphorus, zinc, boron and titanium is more than or equal to 70 g / L, and the content of the composite vitamin is more than or equal to 25 g / L; and amino acids, vitamins and trace elements are new-generation plant growth regulatingnutrition solution preparations, amino acids and trace elements form chelates easily absorbed by plants, and vitamins can regulate in plant growth so as to further improve the fertilizer efficiency and promote the growth of plants, such that the liquid fertilizer can improve the utilization rate of trace elements and promote the growth of plants.

Description

technical field [0001] The invention relates to the field of nutritional preparations for agricultural crops, in particular to a preparation method of liquid fertilizer. Background technique [0002] Existing amino acid liquid fertilizers about zinc and boron are mostly produced with zinc heptahydrate, boric acid added with common amino acids or waste liquid containing amino acids and a certain amount of plant regulators as raw materials. [0003] However, in actual production, the content of ordinary amino acids is low, the dosage is large, and it is easy to absorb moisture and agglomerate when placed for a long time. When dissolved in water, it often floats on the water surface to increase the difficulty of dissolution. Amino acid waste liquid is mostly because the amino acid content is unstable, which easily affects product quality. [0004] At the same time, relevant national policies have classified plant regulators commonly used in fertilizers such as DA-6, gibberelli...
