Embodiment 1

[0057] Add 10kg of anhydrous sodium selenite with a purity of 98% and 25kg of potassium fulvic acid (soluble humic acid ≥ potassium humate, peat-sourced fulvic acid) to 60 kg of deionized water, adjust the pH to 2-3,903 with 60% nitric acid After reacting for 2 hours, add 100kg of absolute ethanol, precipitate, filter, and dry to obtain about 20Kg of organic chelated selenium solid powder or granules.

[0058] 15Kg polysuccinimide (PSI, L-aspartic acid technology, purity ≥ aspartic acid I, weight-average molecular weight 3951, molecular weight distribution index 1.12) and 99% potassium bicarbonate of 20Kg purity add 170kg deionized water, 45 sub-reaction 3h, filtered. Filtrate is cooled to 25 to filter constant temperature, adds zinc alditol of 35Kg purity 98% and the above-mentioned organic chelated selenium that 20Kg makes, stirs to dissolving, obtains about 255Kg translucent organic chelated selenium fertilizer synergist solution. The synergist solution does not change its...

Embodiment 2

[0061] With reference to the method of Example 1, selenium-containing synergistic urea was prepared, the weight average molecular weight of PSI was 4063, and the molecular weight distribution index was 1.05.

Embodiment 3

[0063] Referring to the method of Example 1, a selenium-containing synergistic urea was prepared, the weight average molecular weight of PSI was 5397, and the molecular weight distribution index was 1.96.

Abstract

The invention relates to an organic chelate selenium fertilizer synergist which is prepared from poly-aspartate, organic chelate zinc and organic chelate selenium in a weight ratio of (5-1):(5-20):(3-14), preferably (8-12):(10-15):(6-10). The invention also relates to a method for preparing the synergist, and a fertilizer containing the synergist. According to the invention, inorganic selenium isseparated from organic selenium by ethanol, so as to ensure the content of organic selenium in the fertilizer, and effectively prevent the problem that water insoluble matter is produced by slow chelating of inorganic selenium and poly-aspartate at normal temperature. After the organic chelate selenium is added to the fertilizer, the fertilizer can achieve a non-toxic standard, and after the prepared selenium-containing fertilizer is applied to soil, the residual amount is extremely low, and selenium pollution cannot be caused to the soil, and therefore, the synergist disclosed by the invention can be directly used for single fertilizers and compound fertilizes, and is wide in application scope.

Description

technical field [0001] The invention relates to a selenium-containing fertilizer, in particular to a fertilizer synergist containing organic chelated selenium, a preparation method and application thereof. Background technique [0002] Selenium is the component of human glutathione peroxidase and the prosthetic group of the active part of the enzyme family. It participates in various metabolic processes of human tissues and has functions in the human body such as anti-oxidation, cancer prevention, detoxification, strengthening physical strength, and improving immunity. . The survey report of the Chinese Nutrition Society shows that the daily intake of selenium for adults is only 26.63 glutathione, which is far from the recommended daily intake of 50%. Therefore, selenium deficiency is a common phenomenon in our country, and the lack of selenium intake in the diet seriously affects people's health. [0003] As an important trace element, selenium plays an important role in ...
