Problems solved by technology

However, the supplementary effect of the existing selenium-supplementing fertilizers is poor, and the selenium absorption capacity of grapes is poor, and the grapes cannot be utilized, resulting in selenium waste and low selenium content in grapes.
Moreover, the high content of humic acid-containing water-soluble fertilizers currently on the market are prone to agglomeration during storage, which affects the use

Embodiment Construction

[0029] The present invention will be further described below in conjunction with specific examples.

[0030] EDTA chelated iron (EDTA-Fe) and EDTA chelated magnesium (EDTA-Mg) described in the present invention are commercially available known trace element fertilizers, which can be purchased from Shijiazhuang Jack Chemical Co., Ltd. and the like. The EDTA-Fe contains Fe 12.5-13.5%, and the EDTA-Mg contains Mg 5.5-6.5% (both mass fractions). Potassium humate of the present invention, sugar alcohol calcium and magnesium particles, potassium carbonate, sodium lignosulfonate, potassium lignosulfonate, sodium dodecylbenzenesulfonate are respectively commercially available known raw materials, Wherein, the potassium humate contains 10-12% of potassium and 60-70% of humic acid; the sugar alcohol calcium and magnesium granules contain 25-27% of sugar alcohol calcium and 10-12% of sugar alcohol magnesium. % (all mass fractions), the above raw materials can be purchased from Shandong ...

Abstract

The invention discloses humic-acid-containing water-soluble fertilizer capable of increasing selenium content of grapes, and belongs to the technical field of fertilizer. The humic-acid-containing water-soluble fertilizer comprises, by weight, 180-260 parts of urea, 140-200 parts of monoammonium phosphate, 350-430 parts of potassium sulphate, 2-8 parts of EDTA (ethylene diamine tetraacetic acid) chelated iron, 6-12 parts of EDTA chelated magnesium, 0.5-1.5 parts of amino acid chelated selenium, 45-75 parts of potassium humate, 90-140 parts of sugar alcohol calcium magnesium particles and 20-40 parts of lignosulfonate and / or potassium carbonate and / or sodium dodecyl benzene sulfonate. The invention further provides a preparation method and application of the humic-acid-containing water-soluble fertilizer. The humic-acid-containing water-soluble fertilizer is particularly applied to selenium element absorption in growth period of the grapes, and sugar degree and yield are increased.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and relates to water-soluble fertilizers, in particular to a water-soluble fertilizer containing humic acid that increases the content of grape selenium and its preparation method and application. , trace elements and potassium humate as a whole, provide nutrients for grapes in a balanced and continuous manner, and ensure the needs of grapes for different nutrients in each period of growth. After fertilization, the selenium content in grapes can be significantly increased, and the quality of grapes can be improved. The preparation method is simple and the application effect is good. Background technique [0002] Selenium is one of the essential trace elements for the human body. It has the biological functions of anti-oxidation, anti-inflammation, reducing the accumulation of heavy metals in the human body, improving human immunity, and helping to prevent cancer, protect the liver and protect...
