Plant growth regulator composition with synergistic effect
Technical field
It is a kind of plant growth regulator composition, comprising active component thiophene the invention belongs to agricultural plant protection application field
Benzene is grand and triacontanol or derivatives thereof.
Background technology
Thidiazuron (pyraclostrobin) is new and effective plant growth regulator, after Thidiazuron is absorbed by plants, can
Promote the chorista between petiole and stem, so as to promote mature leaf to come off, the generation of ethene can be stimulated under concentration higher,
Promote the activity of pectin and cellulase.Under conditions of low concentration, with cytokinin effect, the callus of plant can be induced
Differentiation sprouts out.Structural formula is as follows:
Triacontanol is a kind of natural Long carbon chain plant growth regulator, chemical name N-triacontanol, structural formula CH3
(CH2) 28CH2OH, is the natural biological product of the purification from honeybee wax also known as melissyl alcohol.To person poultry harmless and secondary work
With environmentally safe.Flourishing agricultural country, triacontanol is sprayed early in the 1970s and 1980s in 20th century comprehensively, as
Agricultural high yield good harvest, optimizes the plant growth regulator of quality structure, China due to technology imperfection, without sufficient rigorous state
Degree, acts with undue haste, and enters into mistaken ideas.It is national spark program that triacontanol is developed again, is completed in 96 years.30 for radiating the vigour of youth
Alkanol is synchronous with world standard, and it will together turn into the reform structure of agricultural production with " WTO ", optimize product, keep ecological balance, return
Natural, raising yield, for pollution-free food provides important technology material.Triacontanol can absorb via the stem of plant, leaf, then
Promote the growth of plant, the accumulation of increase dry, the permeability for improving cell membrane, the content for increasing chlorophyll, raising are photosynthetic strong
Degree, enhancing amylase, polyoxygenated enzyme, peroxidase activity.Triacontanol energy stratification, take root, cauline leaf growth and bloom,
Make crops precocious, improve setting percentage, enhancing cold-resistant, drought-resistant ability, increase yield, improvement product quality.Triacontanol spreads out
Biology generally includes melissyl phosphate or its salt.Melissyl phosphate (salt) is easily accessible plant and generation in vivo
Triacontanol is gently discharged during thanking, simultaneously because melissyl phosphate (salt) is the molecular structure in triacontanol
On add phosphate (salt), the metabolism to plant produces important influence.
The content of the invention

2nd, drug effect checking test
(1) Assays Example
1st, Thidiazuron and triacontanol compounding are tested sorghum growth regulating synthesis measuring
Thidiazuron and triacontanol acetone are diluted according to finite concentration, cauline leaf spraying is carried out to crop, surveyed in field
Fixed influence of each concentration to plant growth, including plant height, strain footpath, root long, disease-resistant situation, fruit quality to crop, and
Output condition etc. carries out overall merit.
Plant height control rate=(plant height after clear water control plant height-treatment)/clear water control plant height * 100%
Stem diameter increase rate=(the plant stem diameter after clear water adjoining tree stem diameter-treatment)/clear water adjoining tree stem diameter *
100%
The disease index * of preventive effect=(disease index after the disease index-treatment of clear water control)/clear water control
100%
Seed mass of 1000 kernel increase rate=(the seed mass of 1000 kernel after the seed mass of 1000 kernel-treatment of clear water control)/clear water control
Seed mass of 1000 kernel * 100%
The per mu yield * 100% of per mu yield increase rate=(per mu yield after the per mu yield-treatment of clear water control)/clear water control
The Thidiazuron of table 1. is compounded to sorghum growth regulating synthesis measuring summary sheet with triacontanol
Note:" thiophene " is " Thidiazuron " abbreviation in form, and " three " are the abbreviation of " triacontanol ".Dispenser period:Sorghum seedling
Phase dispenser, the stage sorghum plant takes place disease, spraying times:2 times, promote sorghum growing process, ahead of time into
Ripe, effect of increasing production is obvious.
Find have between Thidiazuron and triacontanol and cooperate with castering action very well by testing inventor, Thidiazuron and
Triacontanol mixture under different ratio, with respect to Thidiazuron, triacontanol single dose, and clear water control, adjust by the growth to sorghum
Section effect is obvious, is mainly manifested in:Promote the growth of Chinese sorghum nutritive body, the excessive growth of control sorghum plant, promotion stem slightly increase, prevent down
Volt, promotion spikelet differentiation, improve sorghum itself resistance against diseases, increase kernel weight, improve sorghum synthesis yield.
(2) field efficacy checking test
