Description
Technical field
The invention belongs to technical field of crop cultivation, and in particular to a kind of plant for adjusting iris inflorescence types
Growth regulator and its application.
Background technology
Iris（Phalaenopsis aphrodite）Belong to orchid family Phalaenopsis, is that a kind of perennial torrid zone is grown nonparasitically upon another plant
CAM orchids often make potting or cut-flower, are one of International Flowers most popular in the market " four big cattleyas ".Iris is bloomed
Time and Flowering quality are an important factor for influencing its commodity value, and iris also as most of plant, is needed by one
The nutrient growth of section time, ability environment of accepting stimulate and take out stalk and bloom.The bud differentiation of iris is mainly adjusted by temperature, at
Ripe orchid strain is through certain low temperature（18 ~ 25 ℃）Induction could generate bud, and utilize the method for physics and chemistry can apparent shadow
Ring bud differentiation rate and at flower quality.
Under normal circumstances, the inflorescence of iris includes two types, raceme and panicle.Great Hua type irises
Peduncle without branch, show as raceme；The peduncle of small flower pattern iris has branch more, and one is re-formed on each branch
A raceme, shows as compound raceme.For the iris of great Hua types, single inflorescence types not only influences it
Cut-flower effect, and be unfavorable for single basin put it is ornamental（Great Hua type irises are all combined sale）, it is to limit its ornamental pattern
With bloom a piece number the main reason for.
The inflorescence types of plant depends primarily on its inflorescence branching habit and flower raw relative position.Although different
Higher plant has evolved different floral induction approach, but all is converged all at shoot apex meristem at flower promotion approach
Pass through shoot apex meristem Accelerate bloom.In generative growth phase, the mistake from auxotype to gonotype occurs for shoot apex meristem
Cross, be changed into inflorescence meristem, then differentiate floral meristem from the flank of inflorescence meristem, by floral meristem into
One step differentiates floral organ former base.Raceme is that the flank of main inflorescence meristem is ad infinitum divided into floral meristem；It is multiple
Raceme is main inflorescence meristem after generating a series of branch separate living tissues, then flank be ad infinitum divided into spend it is mitogenetic
Tissue.The inflorescence of great Hua type irises is typical raceme, after shoot apex meristem is converted into inflorescence meristem, flower
Sequence separate living tissue ad infinitum breaks up floral meristem, if needing that compound raceme, inflorescence meristem is induced to must be converted to
Branch separate living tissue and floral meristem, to generate compound raceme.
Artificial synthesized plant growth regulator is passed as a kind of exogenous non-nutritive chemical substance in plant
After being directed at site of action, usually it can promote or inhibit certain links of its life process with very low concentration, be allowed to meeting
The direction of human needs is developed.In general, have its specific purposes per plant growth regulators, and application technology is wanted
Ask quite stringent, only in specific application conditions（Including extraneous factor）With could be to target plant under specific conditions of mixture ratios
Generate specific effect.
So being badly in need of being directed to the racemose characteristic of great Hua type irises, in the process of iris low temperature induction bud
In, specific plant growth regulator composition is imposed, in combination with the physiological development period of characteristic, develops a kind of i.e. suitable work
Factory's large-scale production, and the cost-effective new method for cultivating for improving iris inflorescence types.
Invention content
The purpose of the present invention is to provide a kind of plant growth regulator for adjusting iris inflorescence types and its answer
With.The factory culture of iris, production technology letter may be implemented in the plant growth regulator and its application method economical and effective
It is single, it can effectively improve the inflorescence types of iris, improve the ornamental quality of iris.
To achieve the goals above, the present invention uses following technical scheme：
A kind of plant growth regulator for adjusting iris inflorescence types, including A agent and B agent, A agent is aqua, wherein containing
There is the DA-6 of a concentration of 5.0 ~ 25.0 mg/mL；B agent is organic solvent that can be miscible with water, preferably absolute ethyl alcohol, wherein containing
There are the 6-BA of a concentration of 2.0 ~ 10.0 mg/mL, the KT-30 of the NAA of 0.5 ~ 8.0mg/mL and 0.2 ~ 5.0 mg/mL.
Application of the above-mentioned plant growth regulator in adjusting iris inflorescence types carries out low temperature induction flower in iris
Above-mentioned plant growth regulator is sprayed during bud, it specifically can be in low temperature early period of low temperature induction, low temperature mid-term and low temperature
Later stage sprays, and can also individually be sprayed in one or two period of low temperature induction, and the low temperature induction specific time is early period：1-
20 days, mid-term 20-40 days, 40-80 days later stage；When spraying, per in L clear water, A 8 ~ 10mL of agent are added, B 8 ~ 10mL of agent are added, mix
It is used as spray liquid after closing uniformly；The dosage of spray liquid is to spray 180 ~ 200 plants of Phalaenopsis plants per L spray liquids.
Using the method for adjustment of the iris inflorescence types of above-mentioned plant growth regulator, specifically comprise the following steps：
（1）After cultivating iris, low temperature induction flower_bud formation is carried out；The iris is the butterfly with raceme type
Orchid, it is specific to be, for example,：" interior mountain Miss ", " red coral ", " big rich and honour " or " the ox Prince of the Devils "；
（2）In low temperature early period of low temperature induction bud, low temperature mid-term and low temperature later stage spray plant growth regulator, when spraying, A
The ratio of agent and B agent is 0.8 ~ 1：1；Per in L clear water, A 8 ~ 10mL of agent are added, B 8 ~ 10mL of agent are added, after mixing as spray
Apply liquid use；The dosage of spray liquid is to spray 180 ~ 200 plants of Phalaenopsis plants per L spray liquids；Number is sprayed to be no less than 3 times,
Stop spraying after first flower is buddingged on inflorescence, then normal management；It is specific to spray opportunity and be, for example,：
1st time：When low temperature induction bud start 1-5 days；
2nd time：Start 28-35 days of low temperature induction bud, when the rigid eruption leaf sheath of rachis；
3rd time：Start 50-60 days of low temperature induction bud, when inflorescence shaft length is 6-12cm.
When spraying, standard spray appliance can be used, be preferably usually used in day applying the compression pump of fungicide or insecticide, be convenient for
Plant growth regulator water solution is atomized, make the upper and lower surface of blade all with spray solution and contact；In order to preferably
Plant growth regulator solution is absorbed, processing is sprayed and is preferably selected the progress of bright day gas, in the afternoon 16:00-18:When 00 into
Behavior is good.
Plant growth adjustment can be used for the different phase of iris low temperature induction bud in the application, i.e., in iris first
Piece flower can be used before buddingging, and use scope is more wide in range, have preferable adaptability.
Experiments have shown that after method using the present invention and the plant growth regulator provided, iris rachis flower
It is rachis that 2-3 resting bud of lower section, which is all sprouted, can preferably change the inflorescence types of iris, simultaneously for raising
The flowering quality of iris also has positive effect, and can accelerate the eruption and growth of iris rachis.In general,
The method of the invention is suitble to the factory culture of iris, and production cost is low, consistency is good, obtained iris product product
Matter is high, has the advantages that low input, high yield.
