Abstract

The invention provides a selenium-enriched liquid fertilizer and a preparation method thereof. The selenium-enriched liquid fertilizer is composed of water, ammonium polyphosphate, potassium hydroxide, borax, a zinc fertilizer, copper sulphate, sodium selenite, and at least one of surfactants. The production method comprises the following steps: adding 35-45 weight part of water in a reactor, then adding 35-50 weight part of ammonium polyphosphate for stirring the materials to be fully dissolved, adding 1-3 weight parts of the zinc fertilizer, 1-3 weight parts of copper sulphate, 5-15 weight parts of potassium hydroxide, 1-3 weights part of borax, 1-3 weight parts of the selenium fertilizer, and at least one of 0.2-2 weight parts of the surfactants in order while being stirred until full dissolving is realized. The effective component content is high, quality is stable, and the selenium-enriched liquid fertilizer can be used for promoting growth of crops, increasing output, and increasing quality.

Description

A kind of selenium-enriched liquid fertilizer and preparation method thereof

Technical field

The invention belongs to liquid fertilizer, more specifically to a kind of selenium-enriched liquid fertilizer and preparation method thereof.

Background technology

Selenium is a kind of maintenance indispensable trace element of human normal function, and human body lacks selenium can cause the generation of various disease.Recent studies indicate that, the area of China 72% is in scarce selenium, low selenium band, and in meals, the deficiency of selenium intake drastically influence the healthy of China several hundred million population.According to investigations in the dietary structure of China urbanite, adult's daily intaking amount of selenium is approximately in 20-30 microgram range, and the recommendation 100-240 microgram proposed from Chinese Soclety of Nutrition differs greatly, and is therefore only difficult to meet the normal need of human body by the selenium in natural food.Selenium in environment excessive or lack all can cause human body produce disease.Mend inorganic selenium dosage not easily to grasp, and easily poisoning, medicine selenium supplement is too expensive, and the general consumer group is difficult to bear, and edible Se-rich farm products, it is the safest, most convenient, selenium supplement method most economical, maximally effective that change is built up one's health by taking tonic as tonic.The organic selenium produced due to crop is safer, more effective, so by crop is executed selenium, exploitation Se-rich farm products has wide market prospect.

Summary of the invention

It is an object of the invention to provide a kind of selenium-enriched liquid fertilizer and preparation method thereof, by foliage-spray, make crop Enriching Selenium.To achieve these goals, this invention takes techniques below scheme:

A kind of selenium-enriched liquid fertilizer, its component is water, APP, potassium hydroxide, zinc fertilizer, copper sulfate, Borax, selenium is fertile, at least one surfactant composition, described components based on weight percentage: water is 35%-45%, APP is 35%-50%, potassium hydroxide is 5%-15%, zinc fertilizer is 1%-3%, copper sulfate is 1%-3%, Borax is 1%-3%, selenium fertilizer is 1%-3%, surfactant is 0.2%-2%, described zinc fertilizer is zinc sulfate, zinc chloride, at least one in zinc oxide, described selenium fertilizer is sodium selenite, sodium selenate, any one in selenium dioxide, described surfactant is Polyethylene Glycol, fatty glyceride, fatty acid Pyrusussuriensis is smooth, Polysorbate, dodecylbenzene sodium sulfonate, modified organic silicon.

The preparation method of a kind of selenium-enriched liquid fertilizer, the steps include: 1) in reactor, add the water of 35-45 by weight, it is subsequently adding the APP of weight portion 35-50, stirring, to fully dissolving, obtains solution A；2) adding the copper sulfate of the zinc fertilizer of weight portion 1-3, weight portion 1-3 in solution A, stirring, to fully dissolving, obtains B solution；3) add the potassium hydroxide of weight portion 5-15 to B solution, stirring, to fully dissolving, is subsequently adding the Borax of weight portion 1-3, and stirring is to fully dissolving, and the selenium adding weight portion 1-3 is fertile, and stirring is to fully dissolving；4) it is sufficiently stirred for the surfactant of above-mentioned reactant addition weight portion 0.2-2, obtains finished product.

Compared with prior art, present invention have the advantage that

1. concentration is high.It is no matter a great number of elements content or micronutrient levels all reaches NY1107-2010 standard.

2. instant.Liquid, uniform with pesticide and other solable matter mixture, easy to use, save labor.

3. product stability is good, anti-low temperature crystallization.
