Abstract

The present invention relates to a plant growth regulator composition. The present invention is prepared from aryloxy acid ester substances, plant nutrient substances such as modification dextrin, etc. and compound micro fertilizers such as N, P, K, S, B, Mn, Zn, rare earth, humic acid, etc. by mixture according to the proportion by weight, and the proportion of the aryloxy acid ester substances to the plant nutrient substances to the compound micro fertilizers is (1 to 10): (1 to 20): (10 to 100). The synergistic composition of the present invention has the advantages of obviously enhanced infiltration capacity of active substances for plants, enhanced function effect, multiple effect, stable effect, increased amplitude of increasing yields, etc. The present invention can be widely used for various crops such as rice, wheat, fruit trees, vegetables, etc., and the present invention has the function of regulating growth development, protecting flowers and fruit, improving quality, increasing the content of sugar, maturing in advance, resisting disease, protecting consenescence, etc.

Description

A kind of plant-growth promotor composition

The invention belongs to the plant-growth regulator that contains ester class organic compound.

In recent years, fragrant oxygen acids plant-growth regulator such as p-chlorophenoxyacetic acid (popular name drop-proof agent), p-Iodophenoxyacetic acid (popular name production increasing agent) etc. has been used, and certain effect of increasing production is arranged.But this class growth regulator is acid or sodium salt, ammonium salts.Because acid is insoluble in water, preparation is to need to dissolve with alcohol earlier, therefore uses inconvenient; While is improper as preparation, partial concn is higher, and poisoning then very easily takes place.Though sodium, ammonium salt are water-soluble better, they to the seepage force of vegetable cell a little less than, and is very easily dashed and drench, so plant is not high to the specific absorption of effective constituent, the influence effect by rainwater.In addition,, can not provide nutritive substance simultaneously owing to be single growth regulator, so the effect instability, nutrition does not sometimes catch up with, and causes crop failure on the contrary.

Therefore, overcome and replace the problem that fragrant oxygen acids plant-growth regulator exists, provide that a kind of to prepare plant-growth promotor composition easy to use, that effect of increasing production is stable then be purpose of the present invention.

The technical scheme that realizes the foregoing invention purpose is as follows:

Plant-growth promotor composition of the present invention comprises at least a in the formula I compound

R’n-R1-OR2-COOR3 (I)

R ' comprises chlorine, bromine, iodine in the formula, and R1 is a phenyl, and R2 comprises the alkylidene group of 1-2 carbon, and R3 comprises the straight or branched alkyl of 1～3 carbon, and n is 1～3; Add at least a in little fertilizer such as at least a and potassium primary phosphate in the nutrient for plants such as Zulkovsky starch, sucrose, modification dextrin and α, β, γ cyclodextrin, vitriolate of tartar, borax, boric acid, vitriolate of tartar, manganous sulfate, ammonium molybdate, rare earth, humic acids.The weight quota proportioning of above-mentioned three kinds of components is 1～5: 1～15: 80～100.

Growth regulator in the plant hormone of the present invention is lipophilic fragrant oxygen acid esters class, and it is better than hydrophilic acids to the seepage force of plant materials, and sodium salt or ammonium salt enter in the vegetable cell easily, thereby more can bring into play the effect of activating cells; Relevant bibliographical information, cyclodextrin has the inhibition fungi activity, and can reduce the volatility of activeconstituents and improve solvability, therefore cyclodextrin is both as nutritive substance, play the slowly-releasing solublization again, can also prevent and treat the fungal disease of crop: trace element, rare earth or humic acid fertilizer be the nutritive substance of plant-growth needs especially.

Virtue oxygen acid esters class, nutrient for plants and the fertile three kinds of components of micro-leaf are respectively with 1～5: 1～15: 80～100 weight quota adds that than uniform mixing emulsifying agent commonly used, dispersion agent are the plant-growth promotor composition as auxiliary.

Plant-growth promotor composition applied range can promote crop growth, flower and fruit protecting, improves quality, increase sugar part, can also improve that crop is cold-resistant, the ability of drought resisting, disease-resistant, premature senescence resistance.Be used for paddy rice, wheat, can reduce not plump paddy, big, the full seed of fringe; Being used for citrus, orange, lichee, mango etc. can flower and fruit protecting, improves percentage of fertile fruit, and smooth, individual big, the quality better of fruit surface, and can premature ripening; Be used for cotton, watermelon, vegetables etc. tangible volume increase and disease resistance effect are all arranged.Its volume increase sees following each table for details with protection effect.Table 1, fertilizer are to the effect of increasing production of sweet orange
