Embodiment 1

[0014] Each raw material weight component of the special-purpose chelating fertilizer for celery that the present embodiment involves comprises 19.6 parts of sorbitol, 0.3 part of potassium hydroxide, 21.4 parts of high-purity water, 3 parts of calcium acetate, and 55 parts of calcium nitrate.

[0015] The concrete preparation steps of the celery special-purpose chelating fertilizer that the present invention relates to are as follows:

[0016] (1) Weighing: first take by weight 19.6 parts of sorbitol, 0.3 part of potassium hydroxide, 21.4 parts of high-purity water, 3 parts of calcium acetate, and 55 parts of calcium nitrate for subsequent use;

[0017] (2) Dissolving: Then dissolve 19.6 parts of sorbitol into 21.4 parts of high-purity water and put it into the reactor, set the temperature of the water bath to 65°C, heat at a constant temperature, and keep stirring until the sorbitol is completely dissolved to obtain an aqueous solution of sorbitol;

[0018] (3) Mixing: Then ...

Embodiment 2

[0025] The difference between the present embodiment and Example 1 is: each raw material weight component of celery special-purpose chelating fertilizer is 13 parts of sorbitol, 0.2 part of potassium hydroxide, 14 parts of high-purity water, 2 parts of calcium acetate, 36 parts of calcium nitrate, its preparation and The spraying method is the same as that of Example 1, and only the weight components of the raw materials are replaced. After the application, the yield of celery is increased by 10%, which can significantly promote the growth of celery, promote the quality of celery, and improve the soil structure.

Embodiment 3

[0027] The difference between the present embodiment and Example 1 is: each raw material weight component of celery special-purpose chelated calcium fertilizer is 16 parts in sorbitol, 0.25 part in potassium hydroxide, 17 parts in high-purity water, 2.5 parts in calcium acetate, 45 parts in calcium nitrate, its The preparation and spraying method are the same as in Example 1, only the weight components of the raw materials are replaced. After application, the yield of celery is increased by 13%, the celery is resistant to diseases, the content of nitrate nitrogen is reduced by 18%, and the taste is good.
