Titanium-containing compound, method for producing titanium-containing compound, and use of titanium-containing compound in plant cultivation

摘要

The present invention is a titanium-containing formulation comprising a titanium salt complex with ascorbic acid and citric acid, a preservative, a water-soluble metal sulfate that can be absorbed by plants, wherein the complex is in the presence of acetic acid, For a titanium-containing formulation that is the product of a titanium complexation reaction comprising a mixture of ascorbic acid and citric acid and titanium sulfate in the following mass ratio in an aqueous environment alkalized with magnesium hydroxide: Magnesium (calculated as MgO) And titanium from 1: 1 to 20: 1; ascorbic acid and citric acid from 5: 1 to 3: 5; ascorbic acid and titanium from 7: 2 to 10: 1; magnesium hydroxide (as MgO) Calculated) and acetic acid (calculated as 100% acetic acid) from 8: 1 to 3: 5. The liquid titanium-containing formulation has a pH of 2.5-5.5. The formulation, in the liquid state, desirably contains 2 to 25 g Ti / l and up to 170 g MgO / l. The powdery composition obtained by drying the liquid form is characterized by containing up to 65 g Ti / kg titanium and up to 200 g MgO / kg magnesium. The specification also describes a method for producing a titanium-containing formulation and the use of a titanium-containing formulation that stimulates plant growth.
