Problems solved by technology

[0006] Among the published patents in my country, the application number 200610042683.2 discloses a method for preparing its powder preparation by immobilizing 1-methylcyclopropene with α-cyclodextrin and its derivatives as the main inclusion material. The registered preparations are 3.3%, 0.14%, and 0.014% microcapsule granules. The disadvantage of this type of product is that it needs to cooperate with generators and other equipment to fully release the active ingredient of 1-methylcyclopropene. If it is directly mixed with water During the effective processing time, the active ingredients are rarely released, resulting in a waste of medicines; meanwhile, because the microcapsules are also powder preparations, it is not convenient to weigh and use

Abstract

The invention relates to the technical field of pharmaceutical preparations, and particularly discloses a plant growth regulator-1-methyl propylene effervescent granule / or effervescent tablet and a preparation method thereof. The 1-methyl propylene effervescent granule / or effervescent tablet is prepared from the following raw materials in percentage by mass: 0.01%-20% of 1-methylcyclopropene, 0.5%-15% of a dispersing agent, 0.5%-8% of a wetting agent, 4%-60% of a disintegrating agent, 0-10% of a binder and a filler; and the preparation method comprises the following steps: mixing various raw materials for forming the 1-methyl propylene effervescent granule / or effervescent tablet; and carrying out superfine / airflow smashing, pelletizing, drying, arranging / tabletting, selecting and detecting, so as to obtain the plant growth regulator-1-methyl propylene effervescent granule / or effervescent tablet. The 1-methyl propylene effervescent granule / or effervescent tablet provided by the invention is safe to environment, people, livestock and other beneficial organisms and accurate to meter; a pesticide hazard is not easy to generate; compared with an ordinary encapsulated granule, the 1-methyl propylene effervescent granule / or effervescent tablet is free of dust, high in granular disintegration speed, convenient to use, good in storage stability, and simple in preparation technology and is suitable for industrialized production and large-area popularization and application in the field of preservation of fruits, vegetables and flowers; and effective components can be fully released within the stipulated time during use.

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 1-methylcyclopropene granule / or effervescent tablet and a preparation method thereof. Background technique [0002] Ethylene plays an important role in the storage, transportation and preservation of horticultural products. It promotes the ripening, senescence and shedding of fruits, flowers and leaves, and is called "ripening hormone". In order to prolong the storage life of horticultural products and keep them fresh, it is very necessary to inhibit the synthesis of endogenous ethylene in these organs or prevent ethylene from playing a role. [0003] 1-Methylcyclopropene is a cyclic hydrocarbon containing double bonds. It exists in a gaseous state, is odorless, and has no physiological toxicity. A lower concentration has obvious physiological effects. It competes with ethylene for the binding site on the et...
