Problems solved by technology

At present, there is some research on compound micronutrient fertilizers containing medium and trace elements needed for plant growth. Chelating agents are used to perform chelation reactions with various trace elements, and the obtained chelated trace element fertilizers can increase the yield of crops, but with only Increased crop yields are not enough to meet real demand for vegetables and fruits

preparation example Construction

[0111] Another aspect of the present invention provides a method for preparing a trace element compound fertilizer containing vitamin B, the method comprising the following steps:

[0112] (1) Immerse oligochitosan with a weight-average molecular weight of 3000 to 50000 parts by weight in 2V2vt% acetic acid solution and 2V5wt% hydrogen peroxide solution;

[0113] (2) Dissolving piperazine diketo acid in 10V methanol in parts by weight and adding it to the oligochitosan solution obtained in step (1) to obtain a reaction liquid;

[0114] (3) The reaction solution obtained in the step (2) is adjusted to neutral pH with 10wt% NaOH aqueous solution and then filtered, and the retentate is soaked, washed, filtered and dried;

[0115] (4) Disperse the oligomeric chitosan piperazine diketoamide synthesized in the step (3) in acetone, add 20wt% NaOH aqueous solution for alkalization, and then add abscisic acid and salicylic acid in parts by weight , Carry out the grafting reaction, and finally ...

Embodiment 1

[0124] (1) Grafting piperazine diketo acid onto oligomeric chitosan

[0125] In a 1000ml three-necked flask, add 50g of oligochitosan with a weight average molecular weight of 20000, 100ml of 2vt% acetic acid solution, 100ml of 5wt% hydrogen peroxide solution, stir, completely dissolve and keep it at 55℃ for 5h; after the reaction is complete , Add piperazine diketo acid (1g) dissolved in 10ml methanol, stir and react for 12h at room temperature to obtain the reaction liquid; adjust the pH of the reaction liquid to neutral with 10wt% NaOH aqueous solution, filter, and soak in 200ml acetone for 10h , Wash with 50ml acetone, filter, and dry under reduced pressure at 40°C for 12h.

[0126] (2) Graft abscisic acid and salicylic acid on the oligomeric chitosan modified with piperazinone diacid

[0127] In a 1000ml three-necked flask, add synthetic oligomeric chitosan piperazine diketoamide, 300ml acetone, 100ml 20wt% NaOH aqueous solution, basify at 50℃ for 3h, then add 1.5g abscisic aci...

Abstract

The invention provides a medium trace element compound fertilizer containing vitamin B.The medium trace element compound fertilizer is characterized by at least being prepared from, by weight, 0.1-2 parts of EDTA chelated copper, 3-10 parts of EDTA chelated zinc, 1-7 parts of EDTA chelated iron, 1-6 parts of EDTA chelated manganese, 1-5 parts of EDTA chelated magnesium, 2-8 parts of sodium borate, 2-10 parts of vitamin B, 1-20 parts of diethylaminoethyl hexanoate DA-6 and 3-12 parts of modified chitooligosaccharide.The medium trace element compound fertilizer containing vitamin B has high cold resisting and disease resisting capability, has a significant effect on etiolation caused by medium trace element deficiency of plants and can increase the nutritional ingredients and yield of crops; besides, according to a preparation method of the fertilizer, operation is easy, and the operation environment is safe.

Description

Technical field [0001] The invention belongs to the field of agricultural planting. More specifically, the invention relates to a vitamin B-containing compound fertilizer with middle and trace elements and a preparation method thereof. Background technique [0002] Middle and trace elements play an extremely important role in plant growth. Trace elements refer to a chemical element with very low content in nature. Some trace elements have biological significance and are necessary for the normal growth and life of plants and animals. The role of plants and animals in the body has a strong specificity, which is indispensable and irreplaceable. When the supply is insufficient, plants often show specific symptoms of deficiency. For example, the lack of middle and trace elements during plant growth will cause plant chlorosis. , The yield of crops is reduced, the quality of crops is reduced, and the production may be cut off in severe cases, and the application of fertilizers with medi...
