Problems solved by technology

[0002] At present, most of the intermediate elements added to fertilizers are in the inorganic state, and the use of inorganic intermediate elements in agriculture has the disadvantage of low utilization rate. The main reason is that they are easily fixed by the 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

Embodiment 1

[0017] Add calcium nitrate tetrahydrate, magnesium nitrate, sorbitol, erythritol, mannitol, water and glycerol into the reaction kettle in a mass ratio of 25:13:34:5:20:2:1, at 80°C Carry out the chelation reaction until the calcium nitrate tetrahydrate and magnesium nitrate are completely dissolved to obtain the sugar alcohol chelated middle element. The sugar alcohol chelated middle element is added to the urea production urea, and the sugar alcohol chelates the middle element. The mass ratio of urea to urea is 0.5:99.5. After spraying, drying, cooling and sieving, the chelated urea containing sugar alcohol is obtained.

Embodiment 2

[0019] Add calcium nitrate tetrahydrate, magnesium nitrate, sorbitol, erythritol, mannitol, water and glycerol into the reaction kettle in a mass ratio of 25:13:34:5:20:2:1, at 80°C Carry out the chelation reaction, until the calcium nitrate tetrahydrate and magnesium nitrate are completely dissolved, the sugar alcohol chelated middle element is obtained, and the sugar alcohol chelated middle element is added to the granulation drum of the compound fertilizer and combined with nitrogen fertilizer, phosphate fertilizer and potassium fertilizer Mixing and granulating, the mass ratio of sugar alcohol chelated middle element, nitrogen fertilizer, phosphate fertilizer and potash fertilizer is 5:20:45:30, after drying, cooling and sieving, the compound containing sugar alcohol chelated middle element is obtained fat.

Embodiment 3

[0021] Add calcium nitrate tetrahydrate, magnesium nitrate, sorbitol, erythritol, mannitol, water and glycerol into the reaction kettle in a mass ratio of 25:13:34:5:20:2:1, at 80°C Carry out the chelation reaction, until the calcium nitrate tetrahydrate and magnesium nitrate are completely dissolved, the sugar alcohol chelated middle element is obtained, and the sugar alcohol chelated middle element is added to the liquid fertilizer, and the sugar alcohol chelates the middle element and the liquid fertilizer. The mass ratio is 45:55, and after mixing evenly, a liquid fertilizer containing sugar alcohol chelated medium elements is obtained.

Abstract

The invention relates to a production method of a fertilizer containing sugar alcohol chelated medium elements. The method comprises the following steps: adding the sugar alcohol chelated medium elements into the fertilizer to obtain the fertilizer containing the sugar alcohol chelated medium elements, wherein the mass ratio of the sugar alcohol chelated medium elements to the fertilizer is (0.4 to 50) to (50 to 99.6). Through the production method of the fertilizer containing the sugar alcohol chelated medium elements, the utilization rate of the medium elements after adding the medium elements into the fertilizer is increased.

Description

Technical field [0001] The invention relates to a production method of a fertilizer containing sugar alcohol chelated middle elements. Background technique [0002] At present, most of the medium elements added in fertilizers are in an inorganic state, and inorganic medium elements have the defect of low utilization rate in agricultural applications, mainly because they are easily fixed by soil and phosphorus compounds. And because the inorganic state of calcium and magnesium in the middle element is positively charged and cannot move freely in the plant body, it is easy to cause the problem of accumulation in some places in the plant body and lack in some places, leading to uneven nutrition of the crop. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a method for producing a fertilizer containing sugar alcohol chelated middle elements, which improves the utilization rate of the middle elements after being added to the f...
