Method for preparing organic titanium-plant vinegar potassium salt organic fertilizer through salting-out process

Abstract

The invention relates to a method for preparing an organic titanium-plant vinegar potassium salt organic fertilizer through a salting-out process. The method is characterized by comprising the following steps of: preparing a newly precipitated metatitanic acid by neutralizing an iced solution of a titanium salt with an alkali; using the newly precipitated metatitanic acid to substitute chlorides and sulfates of titanium for being used as a raw material for synthesizing citric acid titanium; taking the newly precipitated metatitanic acid as a titanium source, taking citric acid as an acid solvent and a chelating agent, and synthesizing the citric acid titanium through a microwave hot-melting chelating process; and preparing the organic titanium-plant vinegar potassium salt organic fertilizer by performing neutralization and salting-out on a saturated solution of the citric acid titanium through alkaline plant vinegar compound potassium. According to the method disclosed by the invention, the citric acid titanium with excellent stability and water solubility, which is prepared by microwave hot-melting and full chelating, is taken as a synergist of a plant vinegar potassium organic fertilizer and a crop growth promoting agent.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a method for manufacturing an organic titanium-vegetable vinegar potassium salt organic fertilizer. Background technique [0002] Fertilizer is a strategic material to ensure national food security, and the material basis for maintaining and improving soil fertility to achieve sustainable agricultural development. [0003] Chemical fertilizers are still an important means of production in agricultural production at present, and the absorption and utilization rate of chemical fertilizers in the soil by plants is very low. According to the measurement of my country's current comprehensive agricultural science and technology level, the utilization rate of agricultural crop fertilization in my country is only about 30%, causing a large number of Fertilizer loss and waste and environmental pollution. [0004] The research and development of new fertilizers with high ab...
