Problems solved by technology

Due to these problems in the chelating process of different chelating agents, humic acid exists as a chelating agent: (1) crops with different molecular weights are not easy to absorb; (2) poor chelating ability, chelated compounds are unstable; (3) Not applicable to international organic agriculture
There are trace elements in amino acid as chelating agent chelation: (1) easy to decompose under visible light, easy to flatulence; (2) different sources of amino acid; the effect is quite different; (3) poor chelating ability, chelate is unstable; ( 4) Single sugar alcohols are used as chelating agents, and sugar alcohols are small molecules, which are similar to amino acid chelation, and the chelated products are unstable; (5) the sources of relevant domestic trace elements are their inorganic salts (sulfate, nitrate, Chloride)

Abstract

The invention relates to the field of organic fertilizer chelating, in particular to a compound sugar alcohol chelated medium trace element chelating solution. The composite sugar alcohol chelated medium and trace element chelating solution comprises sugar alcohol, a medium element mixture and a trace element mixture, wherein the sugar alcohol comprises xylitol, erythritol and at least one selected from sorbitol, mannitol, maltitol and isomaltitol, and the mass percent concentration of the xylitol in the chelating solution is 5-20%. The compound sugar alcohol chelated medium and trace elementchelating solution is low in cost, convenient to prepare, safe, harmless to the environment when applied, comprehensive in nutrition, fully water-soluble and easy to absorb, has the quick-acting property of a traditional fertilizer, and can be used for healthily activating and comprehensively improving soil, promoting the morphological transformation of soil nutrients, improving the soil fertilityand thoroughly improving the soil property.

Description

technical field [0001] The invention relates to the field of organic fertilizer chelation, in particular to a trace element chelation solution in complex sugar alcohol chelation. Background technique [0002] Domestic relevant sugar alcohols have been reported successively as chelating agents, and equally all take the vitriol (chlorate, nitrate) of medium and trace elements as raw materials, and patent CN101050136A adds organic acid, sugar alcohols chelating agents to produce chelated zinc, without Many trace elements are produced, and catalysts need to be added. At the same time, there are strict requirements on the heating rate and temperature difference (heating rate 30°C / 10min, temperature difference ≤ 2°C). [0003] CN103159531A is the application of phytoalcohols and medium and trace element salts (sulphate, chloride salt), phytoalcohols (sugar alcohol, isopropanol, inositol, glycerol, ethylene glycol) as small molecule alcohols, chelating Combined instability; CN1035...
