Description
Technical field
The invention belongs to crop planting technical fields, and in particular to a kind of to break wheat seed suspend mode and improve germination percentage
Processing method.
Background technique
Wheat is that one of widest crops are planted in world agriculture, as Three major grain crops, because of its production abundant
" gold " industry is known as with higher use value out.Wheat seed can all be located to improve germination percentage generally
Reason, existing processing method also there are many kinds of, hang well method, refrigeration, mix micromicrofarad etc..Different processing modes corresponds to not
Same effect, these conventional processing methods can improve percentage of seedgermination to a certain extent, shorten germination time, seedling
Full stand, robust seedling.But existing processing method is general to wheat seed dormancy breaking effect, wheat germination rate improves limited, effect
Fruit is unobvious.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of place for breaking wheat seed suspend mode and improving germination percentage is provided
Reason method.
The present invention is achieved by the following technical solutions:
A kind of processing method broken wheat seed suspend mode and improve germination percentage, comprising the following steps:
(1) it by wheat seed exposure 2-3 days under the sun, is then placed at shady and cool ventilation 3 hours；
(2) nano-bentonite is distributed in the zinc citrate solution that mass fraction is 8.5% by the ratio uniform of 20g:200mL,
2 hours are kept the temperature at 80 DEG C, then adjusts the temperature to 30 DEG C, 20min is stirred with 1500r/min revolving speed, obtains suspension, it will be upper
Stating treated, wheat seed is added in suspension in the ratio of 200-220g:300mL, is impregnated 30-40min, is then filtered
Wheat seed out drains naturally；
(1) treated wheat seed 10-15min is impregnated using weak acid solution, weak acid solution and wheat seed ratio are
300-320mL:125g, the weak acid solution pH are 5.2；
(2) it is added drop-wise in the above-mentioned weak acid solution immersed with wheat seed using alkaline solution, until mixed solution pH is 5.7-
When 5.9, stop being added dropwise, stand 1.2-1.6 hour, using first time ultrasonication 4-6s, then proceed to be added dropwise to mix it is molten
Liquid pH to 6.5-6.7 stops being added dropwise, stands 1.2-1.6 hours, using second of ultrasonication 6-10s, then proceed to be added dropwise
When to mixed solution pH to 7.0, stop being added dropwise, stand 2.5-3.5 hours, then filter, use mass fraction for 5% it is anhydrous
Ethyl alcohol impregnates wheat seed 2min, then is filtered, and drains naturally；
(3) treated seed is carried out vernalization 4 hours, can be sowed.
Further, under the sun when exposure, the daily solar irradiation time is not less than 6 hours the wheat seed.
Further, the nano-bentonite granularity is 80nm.
Further, the weak acid solution is 2,3- dyhydrobutanedioic acid solution.
Further, it is 32.5 DEG C that the weak acid solution, which impregnates the soaking temperature of wheat,.
Further, the alkaline solution is the potassium hydroxide solution that pH is 9.5.
Further, the first time ultrasonic power is 400W, frequency 32kHz.
Further, second of ultrasonic power is 320W, frequency 30kHz.
Further, the alkaline solution drop rate is 0.03mL/s.
Further, the germination temperature is 28 DEG C, and relative air humidity 60%, when vernalization is protected from light processing.
The present invention has the advantage that compared with prior art compared with prior art, wheat seed processing method of the present invention,
The present invention carries out immersion treatment to wheat seed by using the suspension that nano-bentonite is mixed with zinc citrate solution, can
Wheat seed cell metabolism is accelerated in the preliminary suspend mode for breaking wheat seed, and wheat seed embryo starts gradually to break up, then by with
Weakly acidic solution is that initial soln impregnates wheat seed, and alkaline solution is then added dropwise again, can constantly change with pH value of solution,
Effective stimulation is constantly generated to Wheat Species chrotoplast, the permeability of the cell membrane of wheat seed can be effectively improved, with place
During reason, the continuous variation of mixed solution intermediate ion concentration, some ions can penetrate into wheat seed cell to a certain extent
It is interior, so as to effectively release the dormant physiology activity of wheat seed, it is embodied in along with the continually changing stimulation of pH,
Then by the continuous variation of mixed solution intermediate ion concentration, in collaboration stimulation wheat seed gluten cell generate amylase and
Accelerate endosperm to decompose, supplies embryo energy, then carry out the ultrasonication of short time twice in intermediate soaking process again, it can
Embryo is reduced in wheat seed to the sensibility of abscisic acid, can influence of the past release abscisic acid to radicle growth, simultaneously, moreover it is possible to
The growth for enough effectively promoting plumule extends, to promote the growth and development of wheat seed, by mixed solution from acyclic acidic
Border tapers to neutral environment, additionally it is possible to directly act on the cell-wall components of wheat seed, can effectively make wheat
Seed cell wall becomes more loose, increases the mobility of film, to promote the extension of cell inside wheat seed, and then promotes
The germination of wheat seed；Processing by the method for the invention can be greatly improved thin in the germination percentage and kind of wheat seed
Born of the same parents' enzymatic activity, significant effect, after the wheat seed germinating that the present invention is handled grows up to plant, the wheat nutrition harvested is richer
Richness, micronutrient levels accumulation ability are greatly enhanced, and especially selenium element content significantly improves, by present invention side
The seedling that the wheat seed that the wheat seed of method processing is handled compared to commonsense method grows up to is neat and much healthy and strong.
