Abstract

The plant growth regulator containing a substd. phenol (or phenate) and methionine is prepared through acidifying, activating, complexing and chelating and serves for making the plant resist cold and drought, promoting surviving, tillering and germination, and increasing yield by 8-15% for grain crops or 15-20% for industrial crops.

Description

Plant growth regulator

The invention relates to

(I) amphyl shown in and methionine are the plant growth regulator that mainly contains effective constituent.(I) X is hydrogen atom or monovalence metal in; R ₁Be hydrogen atom, hydroxy, low alkyl group or lower alkoxy; R ₂Be low alkyl group or lower alkoxy; Methionine is meant D-methionine and L-methionine.

As everyone knows, (I) the represented compound of formula, be widely used in industries such as medicine, agricultural chemicals, spices, dyestuff, day disclosure is speciallyyed permit clear 55-154903 and has been proposed the compound shown in (I) formula as plant growth regulator, can promote the growing of plant significantly, but this method effect is single, and does not activate fully and surface-active-treatment, fails to be absorbed fully by crop.The Japan clear 57-20281 of special permission communique has proposed to be the paddy rice lodging-prevention agent that mainly contains effective constituent, can to prevent the lodging phenomenon that paddy rice causes because of being subjected to typhoon influence, and can promote the growth of crop with methionine.Equally, this method effect is single, and the scope of application is restricted.

China is former vast, and geographical and weather conditions are at a distance of very big, so all presses for and can produce a kind of promotion plant growth, is taking root, germinates, protecting the plant growth regulator that flower, fruit retention, cold-resistant, drought resisting, aspect such as resistant to lodging all have facilitation.The present inventor is through repeatedly research, proposed a kind of with the compound shown in (I) formula and methionine for mainly containing effective constituent, add surface active agent, emulsifier simultaneously, complexing agent and promoting agent are with plant growing nutriment and the micro-plant growth regulator that mixes.

According to the present invention, the compound of said (I) formula be a class have multiple neighbour, to or the compound of meta-isomer, compound as this class has: cresols, orthoresol, metacresol, paracresol, dimethylphenol, 2,4-xylenol, 2,6-two basic phenol, 3,4-xylenol, 3,5-xylenol, paraethyl phenol, carvacrol, Thymol, guaiacol, 2-methoxyl group-4 methylphenol, the 4-ethyl guaiacol, 2,6-syringol, p-t-butyl phenol, p-tert-butyl catechol, butylated hydroxy anisole.This compounds, soluble in water, be a kind of economy, safe, stable compound, also can with insecticide, bactericide, weed killer herbicide, fertilizer together uses, its working concentration is generally 1-1000PPM, according to the difference of crop and difference.In the said plant growth regulator of the present invention, account for 1-5%, be preferably 1-3% (weight, as follows).

According to the present invention, said methionine is two kinds of optical isomers, it is the D-methionine, with the L-methionine, because methionine is the intermediate metabolites in the ethene metabolic processes in the plant corpus, is using under the situation of methionine, has also just improved crop ethene and generated, strengthen the intensity of crop cane, thereby improved crop ability resistant to lodging.Methionine can and liquid carrier, thinner, dispersant is made the aqueous solution or suspension and is used, its consumption is generally 1-1000PPM, is preferably 110-150PPM.The said plant growth regulator according to the present invention, methionine content therein is 5-10%.Be preferably 6-8%.

The said liquid carrier of the present invention is meant liquid organic, and as the vinasse molasses that produced in the wine brewing process, its proportion is 1.13-1.20, and its consumption is preferably 20-25% for the 10-30% of the said conditioning agent of the present invention.

According to the present invention, said surface active agent is meant the glycols compound, as ethylene glycol, and propane diols and butanediol, its consumption is the 20-30% of the said conditioning agent of the present invention, is lower than at 20% o'clock and disperses not exclusively, easily produces precipitation, greater than 30% o'clock, consume excessively, increase cost.

The said complexing agent of the present invention is meant citric acid, EDTA, salicylic acid, sodium potassium tartrate tetrahydrate.This class material not only has good complexing, but also has the cold-resistant short effect of living, and is particularly outstanding in the cold district effect.Its content is the 1-4% of the said plant five long conditioning agent total amounts of invention; According to the present invention, said plant growing nutrients is meant the compound that contains N.P.K and so on, have as this compounds: urea, potassium dihydrogen phosphate, potassium chloride, potassium sulphate, ammonium chloride etc., its content are the 10-20% of plant growth regulator proposed by the invention.Said trace element is Zn, Mn, Fe, Cu, Mo and rare earth element according to the present invention, and its content is the 5-10% of plant growth regulator proposed by the invention, is preferably 7-8%.Because active ingredient and various material proposed by the invention is to coexist with under the pH value, fully mix in order to make them, or form good suspension, emulsifier and integrated agent have also been added, have as this class material: OP-10, Tween 80, peregal, polyoxyethylene and chitin, its content are the 0.01-0.1% of total amount.

According to preparation method proposed by the invention, be that organic matter is carried out acidifying, mixes with acidulant, obtain acidifying solution, the said compound of (I) formula is joined in the activator activate again, add methionine again and just obtain the said activating solution of the present invention; Plant growing nutrients and trace element are joined fully dissolving in the water that boils, add complexing agent again, just obtain the said lysate of the present invention.Lysate is joined in the acidifying solution, fully mix, add activating solution again, after fully mixing, add emulsifier or chelating agent again, after fully mixing, transfer pH value, just obtain the said plant growth regulator of the present invention to 3-4.

Plant growth regulator according to method preparation proposed by the invention, applicable to cereal crops, economic crops, fruit tree, vegetables, flowers, forest etc. after converting water 8000-10000 and doubly diluting, spray the blade face in crops, generally can make the economic volume increase 15-20% that does, cereal crops volume increase 8-15% to promoting the surviving of crop, cold-resistant, drought resisting etc. to have a significant effect, can both play regulating action in each period of plant growing simultaneously.
