Description
Technical field
The present invention relates to technical field of pesticide, and in particular to a kind of plant growth regualting composition, preparation and its application.
Background technique
In the cultivation of gramineous crop such as wheat and rice, the solid tiller that can ear born in early days is known as having
Tiller is imitated, what advanced stage bore cannot ear or ear and acarpous referred to as ineffective tillering.
Chemical Control means are by changing the intracorporal hormonal balance of plant, the growth and development dynamics to change plant
It works, compared with traditional agronomic measures, it directly acts on crop itself, smaller to the dependence of environmental condition.Using
Chemical Control means control ineffective tillering, are comparatively ideal methods.Existing research shows gibberellin, α-naphthylacetic acid, 2,4-D, 2,
4-D propionic acid, 2 first, 4 chlorine etc. have an inhibiting effect to rice tillering, but these substances or because ineffective, or because side effect is big, not
Upper large-area applications can produced.Wherein, only gibberellin has a small amount of application in production at present, and gibberellin, since it can band
Carry out the side effects such as blade and leaf sheath elongation, influences plant type, especially in the case where high fertile and thin planting, spray gibberellin and subtract instead
It produces, the requirement made with high yield rice runs in the opposite direction, thus application area is extremely limited.
Summary of the invention
In view of this, this application provides a kind of plant growth regualting composition, preparation and its application, the composition or

Term " Fen Tiller " refers to the branch that the plants such as grass family occur in below ground or place near the ground.Directly from master
The title level-one tiller issued on basal part of stem tillering node can produce new tiller bud and adventitious root in level-one tiller base portion again, be formed
Secondary level-one tiller.In the good situation of condition, the third level, fourth stage tiller can be formed.What early stage bore can ear solid
Tiller be known as effective tillering, what advanced stage bore cannot ear or ear and acarpous be known as ineffective tillering.Tiller is excessively held
Easily cause group's ventilation and penetrating light bad, the excessively few then Population of tiller is inadequate.Effective tillering determines that final unit area is effective
Spike number is the principal element for constituting yield, and not effective tiller or rate of tillering panicle are The more the better in production, and excessive effectively divides
Tiller causes infertile spikelet number to increase, and grain number per spike, spike weight reduce.And ineffective tillering consumes photoassimilates, is unfavorable for improving production
Amount.
The active components A witchweed lactone plant growth regulator element, controllable lateral bud elongation, plant height, blade-shaped
The growth courses such as shape, aging, seed sprouting, lateral root growth apply witchweed lactone in monocotyledon and dicotyledon
The translocation of auxin can be reduced to reduce the generation of branch.Further, the artificial synthesized analog of witchweed lactone
GR24 can induce suppressing weed seed germination as environmental stimulus model.As allelochemical, growth of mycorrhiza can be promoted, with plant
Object preferably coordinates matter transportation and distribution.The artificial synthesized analog GR24 of witchweed lactone of suitable concentration is applied on plant
The auxins of corresponding site, the level of basic element of cell division parahormone can be reduced.
The active constituent B Prohexadione calcium is a kind of new plant growth regulator.Can by vegetable seeds, root system and
The biosynthesis of Foliage Absorption inhibition gibberellic acid.Prohexadione calcium is poured by seed soaking, is sprayed foliar treatment and is worked, can contract
Stem elongation, the control crop section end growth of much shorter plant, keep stem sturdy, plant is downgraded, and mitigates and prevents from lodging；Adjust ring
Sour calcium can significantly shorten the stem height of the Cereals cultivars such as all rice barleys, wheat, Japanese carpetweed, rye grass；
Prohexadione calcium, which has, promotes Development of ear and grain, improves the effect of crop kernel yield；Meanwhile Prohexadione calcium can also can promote lateral budding
Long and root of hair.In addition, Prohexadione calcium is applied to gramineae plant, the ineffective tillering of gramineae plant increases, and generates to high yield negative
Face effect.
Compared with prior art, detailed description are as follows by the application:
Plant growth regualting composition provided by the invention is by component screening and proportion, using active components A and activity
Ingredient B compounding, the composition or the preparation containing the composition make in gramineous crop, can overcome list using active components A
Promote the side effect of ineffective tillering with active constituent B, reduces gramineae plant ineffective tillering.Active constituent B in composition, can
To downgrade gramineae plant plant, resistant to lodging, the leaf area of increase gramineae plant functional leaf, increase gramineae plant functional leaf
Leaf area chlorophyll content.It is obvious that two active components can increase gramineae plant output results together, and increases for collaboration
Effect effect.
