Embodiment 1

[0063] (1) Preparation of metatitanic acid:

[0064] a. Add 1000ml of ice water at 0℃~5℃ in a 1500ml beaker, and add 10ml hydrochloric acid and 20ml titanium tetrachloride dropwise under the stirring of an electric stirrer to generate a titanium tetrachloride hydrochloric acid solution. Use 10% The sodium hydroxide solution neutralizes the titanium tetrachloride hydrochloric acid solution, and the temperature of the solution is controlled to be ≤5°C and the pH value is 7.0~8.0, so that metatitanic acid precipitates out in cold water ≤5°C;

[0065] b. The newly precipitated metatitanic acid is washed with distilled water to remove chloride ions;

Abstract

The invention relates to a method for preparing organic titanium-plant vinegar ammonium salt organic fertilizer. The method is characterized in that new sediment metatitanic acid is prepared by using alkali to neutralize ice water solution of titanium salt; the metatitanic acid is used to replace titanic chloride and sulfate as raw materials for the synthesis of citricacide-titatnium chelate; the new sediment metatitanic acid is used as a titanium source, the citric acid is used as acid solvent and chelant, and a microwave hot melting chelate technology is used to synthesize the citricacide-titatnium chelate; and then the saturated solution of citricacide-titatnium chelate is subjected to neutralization and salting-out by the alkaline plant vinegar composite ammonium to prepare the organic titanium-plant vinegar ammonium salt organic fertilizer. The citricacide-titatnium chelate prepared by the microwave hot melting chelate technology with excellent stability and water solubility is used as synergist of plant vinegar ammonium organic fertilizer and crop growth promoter.

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 ammonium 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 abs...
