Abstract
Plant growth regulator composition, it is characterised in that be made up of following raw material and its parts by weight：Polypentenol：4.0 10.0%, ethephon (CEPHA),2-(chloroethyl) phosphonic acid：0.0001 0.0005%, piroctone olamine salt：4.0 4.5%, epoxidized soybean oil：0.01 0.1%；Because polypentenol is the chemical substance of natural botanical source, to the metabolic mechanism for having correlation in human body and plant, nontoxic, environmental sound, therefore have great importance using polypentenol exploitation natural green plant growth regulator, it may have good commercial promise.
Description
Technical field
The present invention relates to crop plants growth regulator composition, more particularly, to plant growth regulator composition and
Its preparation method, belongs to agricultural chemicals development field.
Background technology
Plant growth regulator, is the class agricultural chemicals for coordinate plant growth development, including artificial synthesized with day
The compound of right plant hormone similar action and the natural phytohormone extracted from biology.
Polypentenol is also known as Polyprenol.It is isoprene unit（Isopentene group）Into the chemical combination of the most polymerizations of straight-chain
The general name of thing, is widely present in nature.Plant kingdom exists especially has the 9-23 compound of isopentene group.In animal
It is known to exist with 17-22 dolichol of isopentene group.These compounds are characterized in only have hydroxyl（α）It is different
The saturated structures of pentenyl.The microsome of mouse liver contain can glucose from UDP suction pressure to dolichol phosphate on enzyme,
Thus the polysaccharide biosynthesis system with dolichol phosphate glucose as precursor substance for synthesizing.So the physiology of polypentenol
One of function is relevant with the biosynthesis of polysaccharide.Retinol（Vitamin A）It is also the derivative of pentenol, and known and GDP
Mannose reaction becomes retinol phosphomannose.The biological conjunction that polypentenol participates in polysaccharide is more specifically demonstrated in bacterium
Into.
Plant growth regulator is organic synthesis, micro-analysis, plant physiology and biochemistry and Modern Agriculture wooden land skill
The product of various scientific and technical comprehensive developments such as cultivation.20~thirties of 20th century, find to exist in plant micro natural
Plant hormone such as ethene, 3-indolyl acetic acid and gibberellin etc., with the effect that control is grown.To the forties, start artificial
The research of synthetic analogues, develops 2,4-D, diethyl aminoethyl hexanoate successively（DA-6）, CPPU, compound sodium nitrophenolate, α-polypentenol, suppression bud
Pellet etc., gradually promotes the use of, and forms a classification of agricultural chemicals（It is shown in Table）.Artificial synthesized plant growth regulator is got over over more than 30 years
Come more, but because application technology is more complicated, its development is rapid not as insecticide, bactericide, herbicide, using scale also compared with
It is small.But from the point of view of the need for the agricultural modernization, plant growth regulator has very big development potentiality, hair is accelerated in the eighties
The trend of exhibition.China since the fifties production and appliable plant growth regulator.
For target plant, plant growth regulator is the non-nutritive chemical substance of external source, generally can be in plant
Interior conduction can just promote or suppress some links of its life process to site of action, with very low concentration, be allowed to meeting people
Develop the need for class.There is specific purposes per plant growth regulators, and application technology requirement is quite strict, only exists
Specific application conditions（Including extraneous factor）Under could produce specific effect to target plant.Often changing concentration will obtain
To opposite result, for example, there is facilitation at low concentrations, and then become inhibitory action in higher concentrations.Plant growth regulating
Agent has many purposes, different because of kind and target plant.For example：Control rudiment and dormancy；Hestening rooting；Promote cell elongation
And division；Control lateral bud or tiller；Control plant type（Short strong lodging-prevention）；Control is bloomed or male and female sex, induces s.m.p fruit；Dredge
Flower fruit thinning, controls shedding；Control shape or the maturity period of fruit；Enhancing resistance（It is disease-resistant, drought resisting, salt resistance point, freeze proof）；Enhancing absorbs
Fertilizer ability；Increase sugar or change acidity；Improve fragrance and color and luster；Promote latex or resin secretion；Disleave or urge is estimated（It is easy to
Mechanical harvesting）；It is fresh-keeping etc..Certain plants growth regulator is used with high concentration just turns into herbicide, and some herbicides are low
Also growth regulating acts under concentration.
