Problems solved by technology

The concentration of fertilizers in liquid form is limited, and transportation is not convenient; fertilizers in the form of granules and powders are easy to lose, and there will be agglomeration during storage. When using, they need to be stirred and dissolved according to a certain concentration
Both forms of fertilizers are too inconvenient for farmers to use quantitatively in the field, and the use of fertilizers or nutrient solutions on the foliage requires stricter concentration quantitative requirements than soil use. Therefore, it is necessary to develop a new method that is convenient to use and easy to quantify. foliar fertilizer formulation
[0003] Effervescent tablets are widely used in the pharmaceutical industry, and there are also effervescent tablet pesticides in the pesticide formulation processing industry (patent 00107465.2), but there is no fertilizer patent for effervescent tablet formulations yet

Embodiment 1

[0012] Weigh 300g of tartaric acid, 290g of potassium carbonate, 400g of humic acid, and 5g of sodium lauryl sulfate, dry them separately, grind them finely, pass through a 80-160 mesh sieve, and mix them evenly to obtain a premix. Weigh 5 g of polyethylene glycol 6000, dissolve it with 50-100 ml of absolute ethanol, moisten the premix with the solution, press the wet premix into tablets, and obtain 40% humic acid effervescent tablets.

Embodiment 2

[0014] Weigh 240g of citric acid, 200g of potassium bicarbonate, 500g of zinc sulfate, and 30g of sodium lauryl sulfate, dry them separately, grind them finely, pass through a 80-160 mesh sieve, and mix them evenly to obtain a premix. Weigh 30 g of polyethylene glycol 6000, dissolve it with 100-200 ml of absolute ethanol, moisten the premix with the solution, press the wet premix into tablets, and obtain 50% zinc element effervescent tablets.

Embodiment 3

[0016] Weigh 300g of tartaric acid, 290g of potassium bicarbonate, 400g of polyglutamic acid, and 5g of povidone K30, dry and finely grind them, pass through a 80-160 mesh sieve, and mix uniformly to obtain a premix. Weigh 5 g of polyethylene glycol 6000, dissolve it with 50-100 ml of absolute ethanol, moisten the premix with the solution, press the wet premix into tablets, and obtain 40% polyglutamic acid effervescent tablets.

Abstract

The invention discloses a new fertilizer dosage form-foliar fertilizer effervescent tablet and a method for preparing the same. The foliar fertilizer effervescent tablet of the invention is characterized by drying, grinding and sieving the foliar fertilizer or a plant nutrient solution raw powder, an acid inhibitor, a carbon dioxide agent and a surfactant, mixing uniformly, pressing the mixture in a tabletting machine to get the finished product after wetting the mixture by a wetting adhesive. The foliar fertilizer can automatically disintegrate into the plant nutrient solution for foliar spray after the foliar fertilizer is added into the water, and is tend to quantitative use.

Description

(1) Technical field [0001] The invention relates to a new dosage form of fertilizer ----- foliar fertilizer effervescent tablet and a preparation method thereof, belonging to the field of fertilizer processing. (2) Background technology [0002] At present, foliar fertilizers or plant nutrient solutions are mainly in the form of liquids, granules and powders. The concentration of fertilizers in liquid form is limited, and transportation is inconvenient; fertilizers in the form of granules and powders are easy to lose, and there will be agglomeration during storage. When using, they need to be stirred and dissolved according to a certain concentration. Both forms of fertilizers are too inconvenient for farmers to use quantitatively in the field, and the use of fertilizers or nutrient solutions on the leaves of the soil has stricter concentration quantitative requirements than soil use. Therefore, it is necessary to develop a new method that is convenient to use and easy to qu...
