Abstract

The invention discloses a method for producing humic acid magnesium sylvite. The method comprises the following steps: enabling a 5-10% potassium hydroxide solution and humic acid raw powder to react, further adding magnesium sulfate, filtering, and drying the filter cakes, thereby preparing a finished product. The humic acid magnesium sylvite produced by using the method disclosed by the invention contains magnesium elements and potassium elements essential for crops, and the absorption of crops on magnesium elements and potassium elements can be effectively improved. In addition, as the humic acid magnesium sylvite contains organic substances, a function of improving soil can be achieved to a certain extent. The method for producing the humic acid magnesium sylvite has the advantages that no byproduct is generated, the operability is high, the production cost can be effectively controlled, and the like.

Description

The production method of Humic acid Magnesium sylvite

technical field:

What the present invention relates to is a kind of production method of chemical chelatropic reaction Humic acid Magnesium sylvite.

technical background:

There is no the precedent that chemical process produces Humic acid Magnesium sylvite at present.

summary of the invention:

The object of the invention is to provide a kind of containing the magnesium elements needed for farm crop and potassium element, effectively can promote farm crop absorbing magnesium elements and potassium element, containing organic, play the production method of the production Humic acid Magnesium sylvite of the effect of improvement soil.

The object of the present invention is achieved like this:

The production method of Humic acid Magnesium sylvite of the present invention, the method is reacted at 5-10% of mass percentage concentration potassium hydroxide aqueous solution and the former powder of humic acids, then add magnesium sulfate, filters and filter cake is dried obtained finished product.

The production method of Humic acid Magnesium sylvite of the present invention, comprises the following steps:

1) humic acid being crushed to 60-100 orders, adding water and be configured to the solution of 30%-60% w/v, is potassium hydroxide aqueous solution and the humic acid solution reaction of 5-10% by mass percentage concentration, adjust pH to 7.0-8.0;

2) above-mentioned solution stirring is forced into 1-2 normal atmosphere, 60-70 DEG C, insulation 5-8 hours;

3) add magnesium sulfate, add-on and humic acid mass ratio are 1:20-5,60-70 DEG C, insulation 2-3 hours;

4) filtration drying obtains finished product.

The present invention produces the method for Humic acid Magnesium sylvite, has no coupling product, strong operability, and the advantages such as effective production control cost.The Humic acid Magnesium sylvite that the inventive method is produced contains magnesium elements needed for farm crop and potassium element, effectively can promote farm crop absorbing magnesium elements and potassium element.And Humic acid Magnesium sylvite contains organic matter, necessarily depth can play the effect of improvement soil.
