Description
Technical field
The present invention relates to a kind of plant growth regulating substance, specifically, it is related to a kind of containing chitosan and CPPU
The composition of steady quality and its application.
Background technology
According to estimates, the chitin (chitin, chitin, chitin) for being generated in nature is the reserves for being only second to cellulose
Maximum biopolymer, and it is with the functional character abundanter than fiber rope, it be widely present in fungal cell wall,
In the outer skeleton of nematode microfibre sheath, arthropod and many insect gut inwalls.1811, the scientist of France carried from mushroom
A kind of material of like fibrous element is got, and has been named as chitin, be later put in chitin after being heated in NaOH, obtained
A kind of novel substance chitosan is arrived.Chitosan (chitosan), chemical name (Isosorbide-5-Nitrae) -2- amino -2- deoxidation-β-D- Portugals
Glycan, is water-soluble products that chitin is generated after strong lye deacetylate, and molecular weight is generally more than 5000.Due to several
The poor dissolubility of fourth matter, limits its application, and chitosan is then different, not only dissolubility enhancing, and nontoxic,
And with good biocompatibility, it is degradable, so range of application is wider.
CPPU is a kind of phenylurea class plant growth regulator with cytokine activity, can accelerate cell mitogenic point
Split, promote cell increase and break up, prevent fruit and coming off for flower from accelerating the formation of bud, promote stem, leaf, the growth of root, promote
Expanding for fruit, breaks apical dominance, prevents aging, is widely used in agricultural, gardening and fruit tree.But CPPU concentration mistake
Height, while cell division and increase is promoted, easily reduces soluble solid content, increases acidity, slow down coloring, postpone into
It is ripe.
Inventor has carried out the research of substantial amounts of chitosan and CPPU, it was found that one kind contains chitosan and CPPU

Measure of the chitosan CPPU microemulsion of embodiment 8 4.55% to percentage of fertile fruit
7-10d sprays the aqueous solution of 4.55% chitosan CPPU microemulsion (embodiment 2) after crop full-bloom stage,
7-10d is sprayed the 2nd time after 1st dispenser.If 4.55% chitosan oligosaccharide CPPU microemulsion conduct of technique same as Example 2
Medicament is compareed, and separately sets blank, and blank only sprays the water of phase homogenous quantities, and every kind of crop sprays number of times and is 2 times, sprays
The date all same of same crop.Percentage of fertile fruit is counted after spraying, the statistics of percentage of fertile fruit is that can reach the fruit that can be plucked
Quantity accounts for actual reservation and spends several percentages (crop for repeatedly yielding positive results counts percentage of fertile fruit when that can be plucked without a large amount of fruits).
Measure of the compositions-treated of table 2 to the percentage of fertile fruit of crop
Note：The data of last 1 row represent the difference between the 3rd row and the 4th column data in table；
Contain test of the chitosan with the micro-emulsion composition of CPPU to Different Crop percentage of fertile fruit, knot by spraying 2 times
Fruit is shown in Table 2, and the micro-emulsion composition containing chitosan and CPPU is all significantly improved to the percentage of fertile fruit of Different Crop compared with blank,
The percentage of fertile fruit of Different Crop has obvious difference, and compared with chitosan oligosaccharide and the micro-emulsion composition and chitosan list of CPPU
Agent, CPPU single dose are significantly improved under same concentrations to the percentage of fertile fruit of crop.Relative comparison medicament, percentage of fertile fruit is most obvious
Crop is grape, Kiwi berry and strawberry, next to that mango, lichee, apple, pears and pawpaw.
Effect of composition of the embodiment 9 containing chitosan and CPPU to kyoto grape
Chitosan will be pressed with CPPU with 9 containing chitosan and the micro-emulsion composition of CPPU:1、24:1、90:1、
149:1、199:1 totally 5 proportioning, respectively sprayed 1 time in kyoto grape young fruit period, expanding stage, each proportioning treatment spraying 10 plants (examination
Test tree tree vigo(u)r it is basically identical, fruit setting situation is close), often process spray amount it is identical and micro- with the chitosan of identical preparation technology
Emulsion, CPPU microemulsion and chitosan oligosaccharide are to compare with the micro-emulsion composition of CPPU.Plucked on the same day after maturation, determined everywhere
Reason grape single ear counterpoise and 100-grain weight, determine the content of each treatment titratable acid and total Soluble Sugar after 2 days.Titratable acid is used
NaOH titrations (GB GB/T12293-90 fruit, the measure of vegetable product titrable acidity), soluble sugar is dripped using Fehling
Determine method (GB GB 6194-86 water fruits and vegetables soluble sugars determination method).In addition, after plucking 1 day, by the grape 2Kg of each treatment
Impregnated 3 seconds in each proportioning composition 10ppm solution, airing, bagging is placed in 2-5 DEG C of hutch, and grape decayed fruit is checked after 40d
Rate.Aforementioned measurements are shown in Table 3.
Effect of composition of the table 3 containing chitosan and CPPU to grape
Composition containing chitosan and CPPU is shown in Table 3 to the test result of kyoto grape.It can be found that poly- containing chitin
Sugar and the treatment of the micro-emulsion composition of CPPU are above blank and containing chitosan oligosaccharide and chlorine to the spike weight of kyoto grape, 100-grain weight
Micro-emulsion composition treatment, the treatment of chitosan microemulsion and the treatment of CPPU microemulsion of pyrrole urea, and after treatment, it is poly- containing chitin
Sugar is significantly higher with the content of the micro-emulsion composition processing soluble sugar of CPPU, and titratable acid content is relatively low；In addition, containing
The decayed fruit rate that chitosan is processed with the micro-emulsion composition of CPPU is relatively low.In chitosan and the difference of CPPU
In proportioning, chitosan is 90 with the mass ratio of CPPU:Fringe weight, 100-grain weight, the equal highest of content of soluble sugar when 1, can
Titration acid content, decayed fruit rate are minimum, and blank decayed fruit rate is absolutely proved containing chitosan and CPPU up to more than 86%
Fruit weightening, quality, fresh-keeping have clear improvement effect of the composition to grape.
Effect of composition of the embodiment 10 containing chitosan and CPPU to Actinidia deliciosacv.Qinmei
The preparation of testing example 5 is effect of the 5% chitosan CPPU wettable powder to Kiwi berry, with identical work
The wettable powder and chitin of the chitosan wettable powder of skill, CPPU wettable powder, chitosan oligosaccharide and CPPU with
The wettable powder of CPPU is compared.Impregnated 1 time in Kiwi berry young fruit period, with each chemicals treatment young fruit, dip time 3s, often
Individual 10 plants of proportioning treatment（Test tree tree vigo(u)r is basically identical, and fruit setting situation is close）.On the same day in the different plants of every treatment after maturation
100 Kiwi berrys are plucked, each treatment average substance of Kiwi berry is determined.Place, in edible（After plucking 7d）Vc contents are determined,
Vc contents use KIO3 semimicro titration measurings.In addition, after plucking 1 day, selecting the Kiwi berry 50 of each treatment in each proportioning
10ppm solution in impregnate 3 seconds, airing, bagging normal temperature storage, after 35d determine Vc content.Measurement result is shown in Table 4.
Composition of the table 4 containing chitosan and CPPU is to Actinidia deliciosacv.Qinmei substance and the effect of Vc
Composition containing chitosan and CPPU is shown in Table 4 to the test result of Kiwi berry.It can be found that containing chitosan
Wettable powder, chitosan wettable powder, CPPU wettable powder with CPPU, containing chitosan oligosaccharide and CPPU can
WP and the treatment of the wettable powder containing chitin and CPPU are above blank to the substance of Kiwi berry, and poly- containing chitin
The Kiwi berry substance highest that sugar is processed with the wettable powder of CPPU, and exist with the compositions-treated of CPPU containing chitosan
7d and 35d, Kiwi berry Vc contents are above other treatment.Absolutely prove, the composition containing chitosan and CPPU is to macaque
Peach has weightening, fresh-keeping effect.
