[0111] Another aspect of the present invention provides a kind of preparation method containing the trace element compound fertilizer of vitamin B, described method comprises the steps:
[0112] (1) immerse chitosan oligosaccharides with a weight average molecular weight of 3000 to 50000 in parts by weight in 2V 2vt% acetic acid solution and 2V 5wt% hydrogen peroxide solution;
[0113] (2) piperazine diketo acid is dissolved in 10V methanol by weight, then added to the chitosan oligosaccharide solution obtained in the step (1), to obtain a reaction solution;
[0114] (3) filter the reaction solution obtained in the step (2) with 10wt% NaOH aqueous solution to adjust the pH to be neutral, soak, wash, filter and dry the retentate;
[0115] (4) disperse the oligomeric chitosan piperazine diketone amide synthesized in the step (3) in acetone, add 20wt% NaOH aqueous solution, carry out alkalization, then add abscisic acid and salicylic acid in batches by weight , carry out the gra...

[0124](1) Piperazine diketo acid grafted on oligochitosan
[0125] In a 1000ml three-necked bottle, add 50g of chitosan oligosaccharides with a weight average molecular weight of 20000, 100ml of 2vt% acetic acid solution, 100ml of 5wt% hydrogen peroxide solution, stir, completely dissolve and then keep warm at 55°C for 5h; the reaction is over Finally, add piperazine diketopic acid (1g) dissolved in 10ml of methanol, stir and react at room temperature for 12h to obtain a reaction solution; adjust the pH of the reaction solution to neutral with 10wt% NaOH aqueous solution, filter, and soak in 200ml of acetone 10h, washed with 50ml of acetone, filtered, and dried under reduced pressure at 40°C for 12h.
[0126] (2) Grafting abscisic acid and salicylic acid on chitosan oligosaccharide modified with piperazinone diacid
[0127] In a 1000ml three-necked bottle, add synthetic oligomeric chitosan piperazine diketone amide, 300ml acetone, 100ml 20wt% NaOH aqueous solution, alkalinize...
