Problems solved by technology

[0002] At present, most of the intermediate elements used in agriculture are in the inorganic state, and the utilization rate of inorganic intermediate elements in agriculture has the disadvantage of low utilization rate. The main reason is that they are easily fixed by soil and phosphorus compounds.
And because the inorganic state of calcium and magnesium in the middle elements is positively charged, they cannot move freely in the plant body, and it is easy to cause the problem of enrichment in some places in the plant body and lack in some places, resulting in uneven nutrition of crops

Abstract

The invention relates to a production method of sugar alcohol chelated secondary elements. The production method comprises the following steps: adding secondary elements, sugar alcohol and a solvent in a reaction kettle, wherein the mass ratio of the secondary elements, the sugar alcohol and the solvent is 20-50:10-80:0-50; carrying out chelation reaction at certain temperature until the secondary elements are dissolved completely to obtain the sugar alcohol chelated secondary elements. By the product, the utilization rate of the secondary elements can be increased obviously.

Description

technical field [0001] The invention relates to a production method of sugar alcohol chelated middle element. Background technique [0002] At present, most of the intermediate elements used in agriculture are in inorganic state, and the utilization rate of inorganic intermediate elements in agriculture has the disadvantage of low utilization rate, mainly because they are easily fixed by soil and phosphorus compounds. And because the inorganic state of calcium and magnesium in the middle elements is positively charged, they cannot move freely in the plant body, and it is easy to cause the problem of enrichment in some places in the plant body and lack in some places, resulting in uneven nutrition of crops. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a production method for sugar alcohol chelating medium-weight elements, so as to improve the utilization rate of medium-weight elements. [0004] In order to s...
