UNE FORMULE RENFERMANT DU TITANE DESTINEE A LA CULTURE DE VEGETAUX, METHODE DE PREPARATION D'UNE FORMULE RENFERMANT DU TITANE DESTINEE A LA CULTURE DE VEGETAUX ET UTILISATION D'UNE FORMULE RENFERMANT DU TITANE POUR LA CULTURE DE VEGETAUX
According to the invention, a titanium-containing formulation comprises the product of titanium complexation from titanyl sulfate with a mixture of ascorbic acid and citric acid in an aqueous environment alkalized with magnesium hydroxide, in the simultaneous presence of acetic acid, at the mass ratio of magnesium (calculated as MgO) to titanium of 1 :1 to 20:1； ascorbic acid to citric acid of 5:1 to 3 5, preferably 2: 1； ascorbic acid to titanium of 7:2 to 10:1, preferably 4:1 to 6: 1； and magnesium hydroxide (calculated as MgO), to acetic acid (calculated as 100 % acetic acid), of 8: 1 to 3:5. The liquid titanium-containing formulation has a pH of 2.5 to 5.5. In the liquid form, the formulation preferably contains between 2 an 25 g Ti/I and magnesium up to 170g MgO/l. The powdery formulation, on the other hand, obtained by drying the liquid form, comprises titanium up to 65 g Ti/kg and magnesium up to 200 g MgO/kg. In the specification of the invention also describes a method of the preparation of the titanium-containing formulation, and the use of the titanium- containing formulation in the cultivation as a plant growth stimulator.
