Description

Composite plant growth regulator and preparation method thereof

Technical field

The present invention relates to plant growth regulator, specifically composite plant growth regulator and preparation method thereof.

Background technology

Plant growth regulator is as promotion increasing crop yield, and the agricultural chemicals of improvement quality, is widely used.But in actual use, also there are some problems.As gibberellin is applied in fruit tree, flower, fruit retention, the volume increase of swollen fruit can be protected, but generation is simultaneously real really, skin is thick, skin depth, acidity are high, glossiness is bad, fruit size is uneven, affect the grade of fruit.Forchlorfenuron price, cost are high, and dispersiveness is not good, poor permeability, and easily produce malformed fruit, application method is improper, also can produce poisoning.Plant growth regulator single dose current is in addition applied separately more, compound less, sometimes effect is met in order to produce, also be that single dose directly mixes use, just there is unreasonable mixed situation in this, not only well can not play effect of each plant growth regulators, also can increase use cost and affect fruit quality.

Summary of the invention

In order to overcome the deficiency used now in plant growth regulator process, reach cost low, be widely used, effective requirement, the invention provides a kind of composite plant growth regulator.

Composite plant growth regulator of the present invention is wetting powder, and constitutive material and formula thereof are as table 1:

Described chelating agent selects iminodisuccinic acid tetrasodium salt or EDTA.

The compound sodium nitrophenolate (comprising 5-nitroguaiacol sodium salt, sodium onitrophenol and Sodium p-nitrophenoxide) that applied cost of the present invention is low, after application, effect is fast, and penetration, extension are strong.

Forchlorfenuron and compound sodium nitrophenolate Application of composite, increase infiltration and the diffusion of forchlorfenuron, can not produce local over-concentration, produce poisoning, considerably increase effect.

CN104186462A discloses the wax coat of DPPA (diphenyl phosphate azide) to plant leaf surface and fruit surface and produces effectively destruction, the wax greatly reducing blade face and fruit surface is to the inhibition of fertilising and other active ingredient, add absorption, improve absorbing of fertilizer and other active ingredient.Therefore add DPPA and can slough crop leaf wax layer, the speed that speeding-up blade absorbs, reduce dosage, cost reduces.

Boric acid, potassium sulfate, zinc sulphate, magnesium sulfate form the trace element of Chelating state with chelating agent together simultaneously, and the trace element that supplementary crop lacks, absorbs fast, effective.CN104098405A discloses magnesium sulfate, boric acid and zinc sulphate while providing trace element, and anti-continuous cropping effect can also occur, and namely avoids the phenomenon that growing way is bad when Second Year repeats to plant same crops to occur.They are carried out chelating, then can produce the loss that slow releasing prevents in use procedure.

Aspirin in the present invention's formula is also acetylsalicylic acid, aspirin can resolve into salicylic acid and acetic acid in water, and salicylic acid has anti-inflammation and corrosion-resistant effect, and acetic acid can suppress the biologically active of glycolate oxidase, improve the photosynthesis of flowers and trees, increase photosynthetic product.Be used in flowers and trees cultivation and not only can improve survival rate, also impel robust growth, improve resistance, improve stub survival rate, extend the flower arrangement life-span etc.Tian Junhua etc. " magical effect of aspirin in flowers and trees cultivation " (" agricultural knowledge " the 14th phase in 2004) record, flowers and trees stem, branches and leaves are sprayed by the aspirin solution of 500 mg/kg, moisture transpiration in plant body can be reduced, improve the ability that flowers and trees resist drought environment.In conjunction with watering, pouring or sprinkling aspirin (1 kg water dissolves 1), can promote the closed of Stoma of Leaves, and the transpiration reducing leaf water is scattered and disappeared, and reduces burn, the drought resisting of raising flowers and trees, cold tolerance.With aspirin process bonsai, stub advance germination can be made, improve survival rate, shorten and support the base time.Method is: dig in the plant dormancy stage and adopt stub, reduce the surface of a wound during excavation as far as possible, retain fibrous root more, old complaint, deadwood, useless branch are removed simultaneously, the surface of a wound saw saw of thicker root system is flat, withe fruit shear cuts flat, the aspirin solution putting into about 5% soaks 3-5 hour, and the native river sand of basin, rural area soil, wood chip press the proportions of 4: 5: 1, after upper basin, soil is steady and sure, aspirin solution with 5%, as the pouring of normal root water, is finally put in sunshade place.Aspirin has to be made Stoma of Leaves close and prevents wound from producing the effect of jasmonic, arranges flowers, can delay fresh flower and wither the withered time, make fresh flower fresh keeping time extend 7-10 days by the aspirin solution of 0.03%.Flowers and trees, in growth and development process, watered root system 1 time by the aspirin solution of 300-500 mg/kg every 7-15 days, and flowers and trees shoot and leaf growth can be impelled healthy and strong, and blade is plump, and fruit increases, and flower is gorgeous, strengthened ornamental.Aspirin and DPPA with the use of, remove or destroy wax coat at DPPA and impel plant to absorb fast, close Stoma of Leaves by aspirin more afterwards and prevent moisture loss, work in coordination with mutually, bring out the best in each other.

It is Powdered that wetting powder of the present invention refers to product, adds water and stir into suspension when use, can be used by the mode of spraying, spray.

In use, wetting powder of the present invention is watered according to mass ratio 1: 600, stirs evenly as early as possible, spray in blade face immediately.Namely needed amount converts i.e. use, preferably at the cloudy day or use at dusk, avoids using when the sun beats down direct sunlight as far as possible.

Composite plant growth regulator of the present invention is applied to melon and fruit class (also comprising underground tubers) and greengrocery crops, as banana, lichee, longan, strawberry, apple, jujube, peach, mango, melon etc., test confirms, effect of increasing production is obvious, greengrocery can increase production 30 ~ 50%, and melon and fruit class can increase production 25 ~ 35%.

Composite plant growth regulator of the present invention makes melon and fruit grow fast, replaces gibberellin, protects flower, fruit retention, fruit greatly, improves the quality of fruit, grade, increase yield.Its beneficial effect is also: cost is low, toxicity is little, be widely used, effective.

The present invention also provides the preparation method of above-mentioned composite plant growth regulator.

This preparation method comprises:

A) get boric acid, potassium sulfate, zinc sulphate, magnesium sulfate, chelating agent in proportion, stir, make the trace element of Chelating state;

B) all the other components in certain proportion mix;

C) by A), B) gained mixes.
