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 selected from one or more of sodium alkylbenzenesulfonate with 10-14 carbon atoms, 2-amino-5-ethoxybenzenesulfonic acid, 4- (phenylamino) -benzenesulfonic acid and 4- (3, 5-trimethylhexanoyloxy) benzenesulfonic acid.
In a preferred embodiment, the benzene-containing sulfonic acid derivative is sodium alkylbenzenesulfonate having 10 to 14 carbon atoms or 4- (3, 5-trimethylhexanoyloxy) benzenesulfonic acid.
In one embodiment, the weight ratio of the sodium alkylbenzenesulfonate with 10-14 carbon atoms to the 4- (3, 5-trimethylhexanoyloxy) benzenesulfonic acid is 1: (0.8-1.2).
In a preferred embodiment, the weight ratio of the sodium alkylbenzenesulfonate with 10-14 carbon atoms to the 4- (3, 5-trimethylhexanoyloxy) benzenesulfonic acid is 1:1.
in a preferred embodiment, the sodium alkylbenzene sulfonate having 10 to 14 carbon atoms is sodium dodecylbenzene sulfonate.
The sodium dodecyl benzene sulfonate has a CAS number of 25155-30-0 and is purchased from Shanghai Michelin Biochemical technology Co.
The 4- (3, 5-trimethylhexanoyloxy) benzenesulfonic acid had a CAS number of 102568-17-2, available from Acchemica.
The applicant found that the use of sodium alkylbenzenesulfonate having 10 to 14 carbon atoms and 4- (3, 5-trimethylhexanoyloxy) benzenesulfonic acid together to prepare a composition can improve the compatibility of the composition with water, since sodium alkylbenzenesulfonate having 10 to 14 carbon atoms and 4- (3, 5-trimethylhexanoyloxy) benzenesulfonic acid can reduce the surface tension of water, thereby improving the compatibility of the composition with water.
The applicant has found unexpectedly that when sodium alkylbenzenesulfonate having 10 to 14 carbon atoms and 4- (3, 5-trimethylhexanoyloxy) benzenesulfonic acid are used together to prepare the composition, the weight ratio of sodium alkylbenzenesulfonate having 10 to 14 carbon atoms and 4- (3, 5-trimethylhexanoyloxy) benzenesulfonic acid is controlled to be 1: (0.8 to 1.2), the stability of the composition obtained is better, the applicant speculates that the possible reasons are: the sodium alkylbenzenesulfonate with 10-14 carbon atoms and 4- (3, 5-trimethyl caproyloxy) benzenesulfonic acid can generate hydrophilic interaction and hydrophobic interaction with fruit amine, brassinolide, gibberellin and the like in a system, and meanwhile, under specific conditions, the stability of the prepared composition is better due to the electrostatic interaction between the sodium alkylbenzenesulfonate with 10-14 carbon atoms and the 4- (3, 5-trimethyl caproyloxy) benzenesulfonic acid. When the number of carbon atoms of the sodium alkylbenzenesulfonate is too small or too large, the stability of the prepared composition is poor; when the weight ratio of the sodium alkylbenzenesulfonate with 10-14 carbon atoms to the 4- (3, 5-trimethyl caproyl oxy) benzenesulfonic acid is not 1: in the range of (0.8 to 1.2), the stability of the composition obtained is also poor and the efficacy is also affected.
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 adjuvant is selected from one or more of maltodextrin, hydroxypropyl-beta-cyclodextrin, hydroxyethyl-beta-cyclodextrin, 6-O- (2-hydroxypropyl) -beta-cyclodextrin.
In a preferred embodiment, the adjuvant is hydroxypropyl- β -cyclodextrin.
The hydroxypropyl-beta-cyclodextrin had a CAS number of 128446-35-5, available from Shanghai Seiyaku Biotechnology Co.
The applicant found that when hydroxypropyl-beta-cyclodextrin is used as an auxiliary material, the compatibility of the composition with water can be improved, probably due to the special structure of the hydroxypropyl-beta-cyclodextrin, the cavity inside the annular structure of the hydroxypropyl-beta-cyclodextrin has hydrophobicity, the special structure can enable brassinolide to be dynamically included into the cavity, and a plurality of hydroxyl groups are arranged outside the annular structure and have hydrophilicity, so that the compatibility of the composition with water is improved. In addition, the hydroxypropyl-beta-cyclodextrin also 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 auxiliary agent.
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-benzene tetrol, (3R, 4S,5S, 6R) -6- (hydroxymethyl) -2,3,4, 5-piperidine tetrol.
In a preferred embodiment, the adjuvant is ethanol, inositol, glycerol.
In one embodiment, the weight ratio of the ethanol, the inositol and the glycerol is (4-6): (3-5): 1.
in a preferred embodiment, the weight ratio of ethanol, inositol, glycerol is 5:4:1.
the applicant found that when the auxiliary agent consists of ethanol, inositol and glycerol together and sodium dodecyl benzene sulfonate and 4- (3, 5-trimethyl hexanoyloxy) benzenesulfonic acid are simultaneously adopted to prepare the composition, the compatibility of the prepared composition with water is further improved; the applicant speculates that the possible reasons are: in the presence of sodium dodecyl benzene sulfonate and 4- (3, 5-trimethyl caproyl oxy) benzenesulfonic acid, gibberellin in the system can interact with inositol and the like to convert gibberellin into various states such as free state, combined state and the like, so that the compatibility of the composition with water is improved; meanwhile, gibberellin exists in a combined state in a system, can be stably stored in a crop body when being applied, can be mutually converted between a free state and a combined state, can exert physiological effects when seeds germinate, and can be stored in the combined state when the seeds are mature, so that the prepared composition has good efficacy.
In addition, the applicant has found unexpectedly that when hydroxypropyl-beta-cyclodextrin is used as an auxiliary material, and the weight ratio of ethanol, inositol and glycerol is controlled to be (4-6): (3-5): 1, the prepared composition has better drug effect. The applicant speculates that the possible reasons are: under specific conditions, the non-covalent intermolecular forces such as Van der Waals force, hydrophobic bond action, hydrogen bond and the like between the brassinolide and the hydrophobic cavity of the hydroxypropyl-beta-cyclodextrin are combined, so that the inclusion stability and the inclusion rate of the brassinolide and the hydroxypropyl-beta-cyclodextrin are improved, and because the cavity of the hydroxypropyl-beta-cyclodextrin molecule is hydrophobic, the brassinolide is positioned in the cavity at a position which is conducive to the largest contact area between the hydrophobic group and the hydrophobic cavity, and the hydrophilic group of the brassinolide is far away from the hydrophobic cavity as far as possible, so that the hydroxypropyl-beta-cyclodextrin can better include the brassinolide, and the drug effect of the composition is improved. When the weight ratio of the ethanol, the inositol and the glycerol is not (4-6): (3-5): in the range of 1, the pharmaceutical effect of the prepared composition is poor.
According to the invention, the compatibility of the composition and water and the stability of the composition can be effectively enhanced through the synergistic effect among sodium dodecyl benzene sulfonate, 4- (3, 5-trimethyl hexanoyloxy) benzenesulfonic acid, hydroxypropyl-beta-cyclodextrin, inositol, brassinolide, gibberellin and the like, the absorption of crops to active ingredients is increased, and the drug effect of the prepared composition is improved.
In one embodiment, the method of preparing the plant growth regulating composition comprises at least the steps of: mixing gibberellin, benzene-containing sulfonic acid derivatives and auxiliary agents, reacting at 40-55 ℃ for 4-6 hours, sequentially adding brassinolide and auxiliary agents at 30-50 ℃, stirring and mixing for 1-3 hours, adding fruit amine and naphthylacetic acid at normal temperature, and stirring and mixing to obtain the plant growth regulating composition.
In a preferred embodiment, the method of preparing the plant growth regulating composition comprises at least the steps of: mixing gibberellin, benzene-containing sulfonic acid derivatives and auxiliary agents, reacting at 48 ℃ for 5 hours, sequentially adding brassinolide and auxiliary agents at 40 ℃, stirring and mixing for 2 hours, adding fruit amine and naphthylacetic acid at normal temperature, and stirring and mixing to obtain the plant growth regulating composition.
