Embodiment 1

[0050] Example 1 0.1% gibberellin (GA 3 ) preparation of effervescent granules

[0051] The selection and ratio of original drug and auxiliary agent are: 95% gibberellin (GA 3 ) 0.106% of the original drug (0.1%), the dispersant is 2.0% sodium methylene bismethyl naphthalene sulfonate, 4.0% calcium lignosulfonate, 2.0% wetting agent sodium lauryl sulfate, disintegration The agent is sodium bicarbonate 16.0%, sodium carbonate 4.0%, citric acid 15.0%, the binder is dextrin 5.0%, and the filler is attapulgite to make up 100%.

[0052] According to the above proportions, the dosage of each component is calculated, weighed, and mixed evenly; the formula is granulated by ultrafine / jet milling, dried, granulated, and selected. Product testing is carried out according to the quality control indicators of effervescent granules, including the content of active ingredients, wetting time, disintegration rate, foaming property, sieve analysis, shedding rate, pH range and thermal storage ...

Embodiment 2

[0059] Example 2 0.1% gibberellin (GA 3 ) preparation of effervescent tablet

[0060] The selection and ratio of original drug and auxiliary agent are: 95% gibberellin (GA 3 ) original drug 0.106% (0.1%), dispersant is naphthalene sulfonate formaldehyde condensate 3.0%, calcium lignosulfonate 3.0%, wetting agent sodium lauryl sulfate 2.0%, disintegrant is carbonic acid Sodium hydrogen 21.0%, citric acid 17.0%, binding agent is polyvinyl alcohol 5.0%, filler is talcum powder and makes up 100%.

[0061] According to the above proportions, the dosage of each component is calculated, weighed, and mixed evenly; the formula is granulated by ultrafine / jet milling, dried, pressed into tablets, and selected. Product testing is carried out according to the quality control indicators of effervescent tablets, including the content of active ingredients, disintegration time limit, foaming property, sieve analysis, powder and fragment rate, pH range and thermal storage stability, etc. Th...

Embodiment 3

[0069] Example 3 1% gibberellin (GA 3 ) preparation of effervescent granules

[0070] The selection and ratio of original drug and auxiliary agent are: 95% gibberellin (GA 3 ) original drug 1.06% (1.0%), the dispersant is sodium methylene bismethylnaphthalene sulfonate 5.0%, the wetting agent is sodium dodecylbenzene sulfonate 3.0%, and the disintegrating agent is sodium carbonate 8.0% %, sodium bicarbonate 10%, citric acid 18%, binder is sodium carboxymethyl cellulose 3.0%, filler is kaolin to make up 100%. The specific preparation process is the same as in Example 1.

Abstract

The invention discloses gibberellin effervescent granules or tablets and a preparation method thereof. The gibberellin effervescent granules or tablets are prepared from the following raw materials in percentage by mass: 0.01 to 50 percent of gibberellin, 0.5 to 15 percent of dispersing agent, 0.5 to 8 percent of wetting agent, 4 to 60 percent of disintegrating agent, 0 to 10 percent of adhesive and the balance of filler. The preparation method comprises the following steps of: mixing the raw materials for preparing the gibberellin effervescent granules or tablets, performing ultramicro airflow crushing, granulating, drying, finishing grains or tableting, selecting, and detecting to obtain the gibberellin effervescent granules or tablets. The gibberellin effervescent granules or tablets are safe for environment, human, animals and other beneficial organisms, hardly generate phytotoxicity, and are accurate in metering, convenient to use, high in disintegration speed, high in storage stability, simple in preparation process and suitable for industrial production and agricultural large-area promotion and application.

Description

Technical field: [0001] The invention relates to an effervescent granule / or effervescent tablet of a plant growth regulator and a preparation method thereof, in particular to a gibberellin effervescent granule / or effervescent tablet and a preparation method thereof. Background technique: [0002] In 1926, Eiichi Kurosawa of Japan confirmed that gibberellin is the secretion of gibberellin. In 1935, Tejiro Yabuta of Tokyo University in Japan separated and purified gibberellin crystals. So far, more than 70 kinds of gibberellin have been found in plants. The gibberellins produced artificially by Gibberella are mostly GA 3 , GA is also used more in production 4 and GA 7 . Gibberellins are a class of plant hormones that exist widely. Its chemical structure belongs to diterpenoid acids, derived from a tetracyclic skeleton, which stimulates the growth of leaves and buds. Used as a plant growth regulator for potatoes, tomatoes, rice, wheat, cotton, soybeans, tobacco, fruit tree...
