Problems solved by technology

[0010] The existing plant growth regulating composition that inhibits plant growth usually cannot fully exert the effect of each medicinal component in the composition, and cannot achieve synergistic effect
[0011] In addition, when the above-mentioned plant growth regulating composition is prepared into a preparation, usually the polarity difference of the two medicinal ingredients is relatively large, which causes a large difference in the solubility of the two medicinal ingredients in the same solvent.
Therefore, when compounding a composition with a large difference in the polarity of the above-mentioned medicinal ingredients into a preparation, the existing option is to add a large amount of emulsifier and other environmentally unfavorable ingredients when making it into a preparation, otherwise the above-mentioned When the two active ingredients are made into a compound preparation, Ostwald ripening (Ostwald ripening) phenomenon is prone to occur due to the large difference in solubility, which will destroy the suspension system and agglomerate the particles, resulting in the deposition of the active ingredients and the formation of Precipitation, resulting in poor dispersibility of the active ingredient dispersed in the solvent
Thereby affecting the efficacy of the preparations obtained, resulting in a less than ideal effect of inhibiting growth on plants

Embodiment 1

[0056] Embodiment one: Colby's formula method is measured drug efficacy experiment

[0057] Test A:

[0058] 1. Subject: Tobacco

[0059] 2. Experimental method: refer to "Pesticide Indoor Bioassay Test Guidelines NY / T2061.2-2011" Plant Growth Regulator Part 2: Promoting and Inhibiting Plant Growth Test, Pot Planting Method;

[0060] 3. Statistical analysis of data: DPS6.55 (Duncan) statistical software was used for analysis. Calculate the average plant height C1 based on the test data, and the average plant height reduction rate T1 (%) relative to the blank control.

[0061] 4. Evaluation method: use the Colby formula to obtain the average plant height reduction rate E1 after theoretical mixing. Comparing the actually measured evaluation index T1 after mixing with the theoretical index E1 obtained by the Colby formula, the actual value greater than 12% of the theoretical value is a synergistic effect, and the difference between the actual value greater than the theoretical...

Abstract

The invention discloses a plant growth adjusting composition as well as a preparation and an application thereof. The plant growth adjusting composition is composed of following components in parts by weight: A: 1-9 parts of uniconazole and B: 1 part of mepiquat chloride. According to the plant growth adjusting composition, the mepiquat chloride and the uniconazole can be effectively mixed and the growth inhibition effect on plants can also be expressed.

Description

technical field [0001] The invention relates to a plant growth regulating composition, preparation and application thereof. Background technique [0002] Plant growth regulator is an exogenous non-nutritional chemical substance, which can usually be transmitted to the site of action in the plant body, and can promote or inhibit certain links in the plant life process at a low concentration, so that it can It is developed in accordance with the needs of human beings; plant growth regulators are distinguished from general chemical fertilizers or pesticides due to their special functional effects. [0003] Among plant growth regulators, there is a class of compounds that can delay the growth of plants, that is, plant growth retardants, mainly including: chlormequat, methylpiperium, uniconazole, uniconazole, and diethylhydrazide. [0004] Mepiperium, also known as benzylamine, has a chemical name of 1,1-dimethylpiperidinium; its chemical structural formula is as follows: [00...
