In a preferred embodiment, the plant growth regulating composition further comprises 5 to 15 parts by weight of a sulfonic acid derivative containing benzene.

In a more preferred embodiment, the plant growth regulating composition further comprises 10 parts by weight of a sulfonic acid derivative containing benzene.

In one embodiment, the benzene-containing sulfonic acid derivative is one or more selected from sodium alkyl benzene sulfonate with 10 to 14 carbon atoms, 2-amino-5-ethoxy benzene sulfonic acid, 4- (phenylamino) -benzene sulfonic acid, and 4- (3,5, 5-trimethyl hexanoyloxy) benzene sulfonic acid.

In a preferred embodiment, the benzene-containing sulfonic acid derivative is sodium alkylbenzenesulfonate having 10 to 14 carbon atoms or 4- (3,5, 5-trimethylhexanoyloxy) benzenesulfonic acid.

In one embodiment, the weight ratio of the sodium alkyl benzene sulfonate with 10-14 carbon atoms to the 4- (3,5, 5-trimethyl hexanoyloxy) benzene sulfonic acid is 1: (0.8 to 1.2).

In a preferred embodiment, the weight ratio of the sodium alkyl benzene sulfonate with 10-14 carbon atoms to the 4- (3,5, 5-trimethyl hexanoyloxy) benzene sulfonic acid is 1: 1.

The CAS number for the 4- (3,5, 5-trimethylhexanoyloxy) benzenesulfonic acid was 102568-17-2, available from Achemica.

The applicant finds that the compatibility of the composition with water can be improved by jointly preparing the composition by using the sodium alkyl benzene sulfonate with 10-14 carbon atoms and the 4- (3,5, 5-trimethyl hexanoyloxy) benzenesulfonic acid, and the compatibility of the composition with water can be improved because the surface tension of water can be reduced by the sodium alkyl benzene sulfonate with 10-14 carbon atoms and the 4- (3,5, 5-trimethyl hexanoyloxy) benzenesulfonic acid.

The applicant unexpectedly found that when a composition is prepared by using sodium alkyl benzene sulfonate with 10-14 carbon atoms and 4- (3,5, 5-trimethyl hexanoyloxy) benzene sulfonic acid together, and the weight ratio of the sodium alkyl benzene sulfonate with 10-14 carbon atoms to the 4- (3,5, 5-trimethyl hexanoyloxy) benzene sulfonic acid is controlled to be 1: (0.8 to 1.2), the stability of the composition obtained is good, and the applicant speculates that the possible reasons are: the sodium alkyl benzene sulfonate with 10-14 carbon atoms and the 4- (3,5, 5-trimethyl hexanoyloxy) benzenesulfonic acid can generate hydrophilic interaction and hydrophobic interaction with fruamide, brassinolide, gibberellin and the like in a system, and under specific conditions, the prepared composition has good stability due to electrostatic interaction between the sodium alkyl benzene sulfonate with 10-14 carbon atoms and the 4- (3,5, 5-trimethyl hexanoyloxy) benzenesulfonic acid. When the number of carbon atoms of the sodium alkyl benzene sulfonate is too small or too large, the stability of the prepared composition is poor; when the weight ratio of sodium alkyl benzene sulfonate with 10-14 carbon atoms to 4- (3,5, 5-trimethyl hexanoyloxy) benzene sulfonic acid is not 1: when the amount is in the range of (0.8 to 1.2), the stability of the composition obtained is poor and the drug effect is also impaired.

In a preferred embodiment, the plant growth regulating composition further comprises 0.005 to 0.02 parts by weight of an adjuvant.

In a more preferred embodiment, the plant growth regulating composition further comprises 0.01 parts by weight of an adjuvant.

In one embodiment, the adjunct is selected from one or more of maltose cyclodextrin, hydroxypropyl- β -cyclodextrin, hydroxyethyl- β -cyclodextrin, 6-O- (2-hydroxypropyl) - β -cyclodextrin.

In a preferred embodiment, the excipient is hydroxypropyl- β -cyclodextrin.

The CAS number of the hydroxypropyl-beta-cyclodextrin is 128446-35-5, and the hydroxypropyl-beta-cyclodextrin is purchased from Shanghai leaf Biotech limited.

The applicant found that when hydroxypropyl-beta-cyclodextrin is used as an auxiliary material, the compatibility of the composition with water can be improved, which is probably due to the special structure of hydroxypropyl-beta-cyclodextrin, the inner cavity of the ring structure has hydrophobicity, the special structure can enable brassinolide to be dynamically included in the cavity, and the outer part of the ring structure has a plurality of hydroxyl groups and has hydrophilicity, so that the compatibility of the composition with water is improved. In addition, the hydroxypropyl-beta-cyclodextrin has good biodegradability and no pollution to crops and environment.

In a preferred embodiment, the plant growth regulating composition further comprises 20 to 30 parts by weight of an adjuvant.

In a more preferred embodiment, the plant growth regulating composition further comprises 25 parts by weight of an adjuvant.

In one embodiment, the adjuvant is selected from one or more of ethanol, inositol, pinitol, glycerol, 4- (1-hydroxyethyl) -6-methyl-1, 2,3, 5-benzenetetraol, (3R,4S,5S,6R) -6- (hydroxymethyl) -2,3,4, 5-piperidintetraol.

In a preferred embodiment, the adjuvant is ethanol, inositol, glycerol.

In one embodiment, the weight ratio of ethanol, inositol and glycerol is (4-6): (3-5): 1.

in a preferred embodiment, the weight ratio of ethanol, inositol and glycerol is 5: 4: 1.

the applicant finds that when the auxiliary agent consists of ethanol, inositol and glycerol together, and the composition is prepared by using the sodium dodecyl benzene sulfonate and the 4- (3,5, 5-trimethyl hexanoyloxy) benzene sulfonic acid, the compatibility of the prepared composition with water is further improved; the applicant speculates that possible reasons are: under the existence of sodium dodecyl benzene sulfonate and 4- (3,5, 5-trimethyl hexanoyloxy) benzene sulfonic acid, gibberellin in the system can interact with inositol and the like to convert the gibberellin into various states such as a free state, a combined state and the like, so that the compatibility of the composition with water is improved; meanwhile, as gibberellin exists in a system in a bound state, the gibberellin can be stably stored in the bodies of crops during application, can be mutually converted between a free state and a bound state, can exert physiological effects when seeds germinate, and can be stored in a bound state when the seeds mature, so that the prepared composition has good drug effects.

In addition, the applicant unexpectedly finds that when hydroxypropyl-beta-cyclodextrin is used as an auxiliary material, the weight ratio of ethanol to inositol to glycerol is controlled to be (4-6): (3-5): 1, the prepared composition has better drug effect. The applicant speculates that possible reasons are: under specific conditions, non-covalent intermolecular forces such as van der waals force, hydrophobic bond effect, hydrogen bond and the like between hydrophobic cavities of the brassinolide and the hydroxypropyl-beta-cyclodextrin act together to improve the inclusion stability and the inclusion rate of the brassinolide and the hydroxypropyl-beta-cyclodextrin, and because the cavities of hydroxypropyl-beta-cyclodextrin molecules are hydrophobic, the brassinolide is positioned at a position which is favorable for the maximum area contact between a hydrophobic group and the hydrophobic cavities in the cavities, and a hydrophilic group of the brassinolide is far away from the hydrophobic cavities as possible, the hydroxypropyl-beta-cyclodextrin can better include the brassinolide, so that the drug effect of the composition is improved. When the weight ratio of ethanol, inositol and glycerol is not (4-6): (3-5): 1 range, the efficacy of the prepared composition is poor.

The synergistic effect of sodium dodecyl benzene sulfonate, 4- (3,5, 5-trimethyl hexanoyloxy) benzene sulfonic acid, hydroxypropyl-beta-cyclodextrin, inositol, brassinolide, gibberellin and the like can effectively enhance the compatibility of the composition with water and the stability of the composition, increase the absorption of crops to effective components and improve the drug effect of the prepared composition.

In one embodiment, the plant growth regulating composition is prepared by a process comprising at least the steps of: mixing gibberellin, benzene-containing sulfonic acid derivatives and auxiliaries, reacting for 4-6 hours at 40-55 ℃, sequentially adding brassinolide and auxiliary materials at 30-50 ℃, stirring and mixing for 1-3 hours, adding fructosamine and naphthylacetic acid at normal temperature, stirring and mixing to obtain the plant growth regulating composition.

In a preferred embodiment, the plant growth regulating composition is prepared by a process comprising at least the steps of: gibberellin, sulfonic acid derivatives containing benzene and an auxiliary agent are mixed and then react for 5 hours at the temperature of 48 ℃, brassinolide and the auxiliary material are sequentially added at the temperature of 40 ℃, after stirring and mixing for 2 hours, carpronium and naphthylacetic acid are added at the normal temperature, and the plant growth regulating composition is prepared after stirring and mixing.

In a second aspect of the present invention, there is provided a plant growth regulator comprising the plant growth regulating composition described above.

Methods of use of the plant growth regulating compositions: mixing a plant growth regulating composition with water in a ratio of 1: 1000 by weight ratio, and mixing.
