Description
Technical field
The present invention relates to agricultural horticultural field, in particular to a kind of defoliant, for fallen leaves composition and its answer
With.
Background technique
Normally, based on transplanting or other such as carry, the needs of lodging-prevention etc., various plants may be wanted
Ask the removing processing for carrying out branch, blade etc..If blade, tree fork etc. can be made in advance to fall off, make after planting again new
Leave will preferably complete transplanting, the transhipment purpose of plant.
Know according to inventor, the specific organization position of leaf, flower or fruit handle and its own is related from falling off for plant main body.
When the process of falling off starts, the cell wall at the position that falls off becomes soft and makes it possible organ falling off under mechanical action,
Such as in wind-force, or falling off under organ self gravitation effect.However, this be not always occur when needed, or
It is not to occur to required degree.Thus, in a certain time or a certain stage of plant growth, with artificial controllable mode
It is advantageous to reach this process.
Generally, artificial specific purpose removing leaf etc. can be realized using mechanical means or chemical method.Machinery side
Leaf, branch etc. are realized that disleave is handled by various mechanical equipments by method in a manner of pulling out, wipe out etc..Chemical method is mainly
Refer to the processing for the removing blade etc. such as acting on plant, and make leaf by using specific chemical reagent.
In the related technology, the main path of chemical method removing blade, which has using herbicide, carries out disleave.Generally adopted
Herbicide such as paraquat, glyphosate, disleave phosphine etc..After herbicide spraying, plant makes a response to the injury of herbicide
And ethylene is generated, cause leaf abscission.
The multipair plant injury of these herbicides is big.If paraquat effective component is to the chloroplast membranes damage layer power pole of plant
By force, terminate photosynthesis and Chlorophyll synthesis quickly, no conduction can only make medicine position aggrieved.The sweet unicorn of grass is mainly led to
The cauline leaf for crossing weeds absorbs and conducts complete stool, interferes the biosynthetic process of phenylalanine and tyrosine, and makes dye in nucleus
Colour solid is not normal, keep weeds withered etc..Alternatively, can also be killed using fallen leaves acid etc. to plant leaf, to promote to fall leaf.
Therefore, plant is made quickly to fall leaves, and plant can restore just to seem more important within the shorter time.So
And the means of the problem are not well solved in existing technology.

Specific embodiment
Embodiment of the present invention is described in detail below in conjunction with embodiment, but those skilled in the art will
Understand, the following example is merely to illustrate the present invention, and is not construed as limiting the scope of the invention.It is not specified in embodiment specific
Condition person carries out according to conventional conditions or manufacturer's recommended conditions.Reagents or instruments used without specified manufacturer is
The conventional products that can be obtained by commercially available purchase.
A kind of defoliant below for the embodiment of the present invention, the composition for fallen leaves and its application carry out specifically
It is bright:
It is typically based on special demand, the leaf that needs to carry out plant to fall off processing.Such some demands for example may
It is to need to transplant plant.Due to transplanting after plant growth environment change, the moisture and Nutrient Absorption of plant root and
Transporting will weaken, and the presence of leaf will accelerate the consumption of its moisture scattered and disappeared with nutrition.It, can be with by removing leaf
Realize the scattering and the demand of nutritional ingredient for reducing moisture, to a certain extent so as to plant recovery growth.
It is apparent that being a kind of scheme by mechanical removal leaf, still, it is contemplated that its complexity realized, using chemistry
Reagent removing leaf is another optional scheme.For example, selecting classes of herbicides substance in the related technology to remove leaf.
However, inventor thinks its difficulty or ease will be made to be fitted in specific demand using the inherent defect of herbicide removing leaf
With.For example, removing leaf is expected to be unlikely to kill plant, so as to can also be again after plant removes a period of time after leaf
Raw leaf or the normal growth for keeping plant.Based on this, it is different from and fallen leaves processing is carried out using herbicide in the related technology,
Using 2 chloroethyl phosphoric acid as the active constituent of fallen leaves in example of the present invention.
2 chloroethyl phosphoric acid can be as hormone control substance to adjust the intracorporal hormonal balance of plant, and then accelerates thin
Born of the same parents' naturally-aged process, so as to cause disleave.Substantially, 2 chloroethyl phosphoric acid can adjust the production of the endogenous sex ethylene of plant
It gives birth to and itself can also discharge ethylene, and ethylene can accelerate the aging of the various organs of plant.For example, ethylene action in plant from
Floor area such as petiole, carpopodium, petal base portion.It promotes to remove cellulase again in absciss layer by promoting the synthesis of protein to increase
Synthesis, accelerates absciss layer and is formed, organ is caused to fall off.
However, in the related art, inventors have found that 2 chloroethyl phosphoric acid is usually used to the carry out accelerating ripening of fruit, and fruit
For real dematuration significantly due to defoliation effect, defoliation effect is unsatisfactory to be widely used its difficulty or ease.In addition, in order to more
Fastly, more thoroughly leaf is made to fall off, it is often desirable to after plant is processed, can be combined factor of natural environment (such as wind,
Rain) condition promotion fallen leaves.It and for falling leaves not is its ideal Land use systems in view of 2 chloroethyl phosphoric acid, and it is in wind and rain
Under the conditions of can not good ground cover plant utilize.
Therefore, in the present example, improve 2 chloroethyl phosphoric acid applicability using auxiliary agent, carry out disleave using it
When, cooperated jointly with bleeding agent and spreader-sticker to improve defoliation effect.Spreader-sticker can make include 2 chloroethyl phosphoric acid activity
Ingredient more fully can sprawl and be attached to leaf, and make quickly to seep with the well-bound active constituent of leaf by bleeding agent
Thoroughly, it is absorbed by plants.In this way, the composition for fallen leaves is less susceptible to separate with leaf, and can be utilized in a short time,
And it is unlikely to before unutilized to be separated by rainwater or wind-force effect with leaf.
In example of the invention, 2- chloroethyl phosphine, bleeding agent and spreader-sticker are provided in the form of compositions, and its
The composition that can be used in fallen leaves can be applied to blade so that blade falls off from plant.Composition includes active constituent and helps
Agent, active constituent include 2 chloroethyl phosphoric acid, and auxiliary agent includes bleeding agent and spreader-sticker.
In order to balance cost and its defoliation effect, the content of active constituent can be selected as 65~75wt%.For example,
The content of active constituent is 65wt%, and the content of auxiliary agent is 35wt%.Alternatively, the content of active constituent is 68wt%, auxiliary agent
Content is 32wt%.Alternatively, the content of active constituent is 70wt%, the content of auxiliary agent is 30wt%.Alternatively, active constituent contains
Amount is 74wt%, and the content of auxiliary agent is 26wt%.
Active constituent can also add some other disleave ingredients, example other than it can use 2 chloroethyl phosphoric acid
Such as, Benzazole compounds.In the related technology, there is also use chlorate (can be potassium chlorate, magron) to carry out disleave.
But chlorate has chloranion, and because its strong oxidizing property has deleterious effects to the growth of plant, and when continuing longer
Between.Due to having bleeding agent and spreader-sticker in the composition in example of the present invention, thus aggravation chlorate is easier to the wound of plant
Evil, therefore the composition in example of the present invention and chlorate share can enhance disleave, but also plant is caused to be difficult to the short time
The injury of recovery.
In a kind of example, the dosage of active constituent is 70%, and the dosage of bleeding agent is 28%, and the dosage of spreader-sticker is 2%.
Since in some instances, active constituent, bleeding agent, spreader-sticker are provided and are used in the form of non-pure material, therefore, i.e.,
Active constituent is provided using the main component as the first raw material；Bleeding agent is provided using the main component as the second raw material；
Spreader-sticker is provided using the main component as third raw material.In example, purity (the active constituent such as 2- chloroethyl of the first raw material
The content of phosphonic acids is that 40%) dosage is 75%, and purity (content of bleeding agent such as organosilicon is 60%) dosage of the second raw material is
20%, purity (content of spreader-sticker such as Panongchus citri is 15%) dosage of third raw material is 5%.
It further, can also be to the bleeding agent in auxiliary agent other than the dosage to active constituent and auxiliary agent is adjusted
It is selected with spreader-sticker dosage.For example, in auxiliary agent, the content of bleeding agent and content ratio >=1 of spreader-sticker.It is some to replace
In the example in generation, the dosage (weight) of bleeding agent and spreader-sticker is 1:1 or 2:1 or 3:1 etc., or, 12:1.
The optional ingredient having suitable for soaking, permeating and sprawl of bleeding agent, such as bleeding agent can be used by selection in example
Organosilicon, such as silicone oil (such as polyether modified silicon oil), silicone resin, polyoxyalkylene modified polymethyl siloxane (L-77, Silwet
The product of company), dimethicone copolymerization polyol, dimethicone copolymerization polyol etc..Organosilicon can be to
Lower general formula (1) indicates:
R in formula (1)1Expression-CnH2nO(C2H4O)a(C3H6O)bR2.Wherein x=1, n=3, a=6~9, b=0~3, a+b
Performance is more excellent when=6~9；R2=-COCH3Or-CH3Or-H.
Spreader-sticker can use Panongchus citri using including that spreader-sticker is optional in surfactant, such as example.For example,
2 chloroethyl phosphoric acid 35wt%, organosilicon 50wt%, Panongchus citri 15wt%.
Based on the above composition for fallen leaves, a kind of defoliant is additionally provided in example.Defoliant is mainly by for falling
The composition of leaf is constituted.
Optionally, it in order to which aforementioned composition is made as various dosage forms appropriate, can be added on demand not in defoliant
Same auxiliary material.I.e. defoliant includes preparation auxiliary material.In some instances, preparation auxiliary material includes wetting agent, dispersing agent, emulsification
Agent, thickener, solvent, antifreezing agent, preservative, disintegrating agent, stabilizer, film forming agent, encapsulating agent, pH acid-base modifier, defoaming agent,
The combination of one or more of colorant, filler.Two or more combinations may is that wetting agent and dispersing agent；Or, newborn
Agent and thickener；Or, thickener, solvent and antifreezing agent；Alternatively, preservative, disintegrating agent and stabilizer；Alternatively, pH is sour
Alkali regulator, defoaming agent, colorant and filler.
Correspondingly, according to different needs, and auxiliary material the difference used, defoliant can be by with different dosage form quilts
Production.The dosage form of defoliant for example can be missible oil, suspending agent, wettable powder, aqua.Wherein, missible oil appearance transparent, nothing
Grain, impurity, without layering, without precipitating, dispersibility in water is also relatively good.The ratio of suspending agent is great, small in size.
The production method of defoliant can usually be selected as mixing the various components in composition.It such as needs to make spy
Determine the defoliant of dosage form, composition can be mixed with corresponding auxiliary material.
Application is watered in addition, may be selected to use using defoliant for convenience.The amount of being watered for example can choose as defoliant:
Water is 1:150~200 (weight ratio), can also be 1:160~190 or 1:170~180 or 1:150~180 etc..I.e. 1 kilogram
Defoliant and 156 kg of water are mixed into diluent (dispersion liquid).Alternatively, 1 kilogram of defoliant and 185 kg of water are mixed into dilution
Agent.
The method of application of defoliant, which can be, to be sprayed.Such as be uniformly sprayed at diluent such as achieved above on leaf,
Enable leaf sufficiently drenched.After spraying for the first time, if can lower drug effect in case of rained after 4 hours, may be selected to respray.Optionally, it falls
Leaf agent is used in fine day.
Through practical proof, in some optional examples, inventor has found plant can be made to exist using above-mentioned defoliant
Start to fall leaf after 24 hours, and leaf is fallen completely in 36 hours.Plant starts to sprout after fallen leaves after 15 days,
And tree crown restores the growth conditions to fallen leaves in 40 days.The defoliant that example of the present invention provides is to plant and person poultry harmless.Its
Fallen leaves effect is mainly reached by the nutrition transmission interrupted between leaf and branch, it is naturally raw that it is still able to maintain when leaf is fallen
Long status such as color (greenery).
Composition in example and the defoliant based on its production can be adapted for the fallen leaves demand of various plants, such as
Evergreen or half aiphyllium or fallen leaves megaphanerophyte etc..In example, defoliant is employed to that Qiu Feng and leaflet Lan Ren is made to fall leaves, and table
Apparent fallen leaves effect is revealed.
