NOVELTY - Preparing an organic titanium-fulvic acid urea by a microwave hot-melting process, comprises: e.g. (a) neutralizing an ice solution of titanium salt with alkali to prepare a new precipitate metatitanic acid that contains no chlorine and sulfur ions and is insoluble in citric acid; (b) replacing the titanium chloride and titanium sulfate with the new precipitate metatitanic acid, which contains no chlorine and sulfur ions and is insoluble in citric acid, as the raw material for synthesizing the titanium citrate without chlorine and sulfur ions.    USE - The method is useful for preparing an organic titanium-fulvic acid urea by a microwave hot-melting process.    ADVANTAGE - The method is capable of peparing the organic titanium-fulvic acid urea in an environmentally friendly manner.    DETAILED DESCRIPTION - Preparing an organic titanium-fulvic acid urea by a microwave hot-melting process, comprises: (a) neutralizing an ice solution of titanium salt with alkali to prepare a new precipitate metatitanic acid that contains no chlorine and sulfur ions and is insoluble in citric acid; (b) replacing the titanium chloride and titanium sulfate with the new precipitate metatitanic acid, which contains no chlorine and sulfur ions and is insoluble in citric acid, as the raw material for synthesizing the titanium citrate without chlorine and sulfur ions; (c) using the new precipitate metatitanic acid, which contains no chlorine and sulfur ions and is insoluble in citric acid, as the titanium source, using the nitric acid as the acid solvent and the chelating agent, synthesizing the titanium citrate without chlorine and sulfur ions by a microwave hot-melting and chelating process; (d) neutralizing and salting out the saturated solution of titanium citrate with ammonium carbonate powder to prepare a titanium citrate-ammonium citrate composite salt; (e) matching the titanium citrate-ammonium citrate composite salt with ammonium fulvate salt, performing hot-melting and chelating reatment in the microwave to prepare an organic titanium-ammonium fulvate composite salt; and (f) mixing urea with the organic titanium-ammonium fulvate composite salt, placing the mixture into the microwave for performing hot-melting and chelating treatment to obtain a fulvic acid urea compound fertilizer containing organic titanium.
