Abstract
The present invention provides a kind of cotton seeds germination accelerating method, and the germination accelerating method includes：Lint, seed selection, medicine process, seed soaking pre-treatment, soak seed, cultivate, looking into bud.The present invention can significantly improve the fresh and alive quality of germination percentage, germinating energy and sprout of cotton seeds.
Description
Technical field
The present invention relates to cotton breeding technical field, and in particular to a kind of cotton seeds germination accelerating method.
Background technology
Cotton seeds occupy very important status as the most basic means of production, in Cotton Production.Cotton seed germinates
Rate is one of important indicator of cotton seed quality, with polish cotton seeds such as the continuous improvement of cotton seed industrialization degree, lint, coatings
It is commonly used in production, increase substantially cotton seed quality, especially germination rate of cotton seed is significantly improved.But due to a variety of originals
Cause, every year because germination rate of cotton seed problem is still very serious to the loss that production is caused, the detection work for carrying out germination percentage is very heavy
Will.
The country is also relatively on the low side for the research of the Germination Technique of cotton seeds at present, in the industry general just adopt or Cotton Gossypii
The Stratification technique of seed, Main is：In the container of cleaning, load 50～55 DEG C of warm water, the water yield is 5 times of seed volume,
Seed is immersed in warm water and is stirred continuously, is stopped stirring when water temperature drop is to 30 DEG C, then is soaked 8～12 hours, make seed
Moisture is suctioned, then water outlet, drained away the water, bound up with gauze, outside wraps the piece of sack or towel for soaking again, puts in basin alms bowl
Row accelerating germination, this method are referred to as hoting water treatment of seeds, and this is germination accelerating method the most frequently used at present, and this method is simple and convenient, but also deposits
In problems：Seed sprouting is slow, and bud gesture is weak, it is irregular to emerge, and big seedling phenomenon is serious, such as seed dormancy, speed of emerging
Degree is slower, and bud rate is low.Cotton Gossypii is a kind of very popular crops, occupies critical role in production, but cotton seeds are sent out
Bud is slow and irregular, and in storage process, easy naturally-aged causes vigor to reduce, therefore how to accelerate seed sprouting and promote to plant
Son is emerged and seems particularly significant.
The content of the invention
It is an object of the invention to provide a kind of cotton seeds germination accelerating method, it can significantly improve cotton seeds germination percentage,
Germinating energy and the fresh and alive quality of sprout.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention comprises the steps：
S1, lint, to the high residual fine hair seed for obtaining, direct lint is processed into light seed；
S2, seed selection, light seed Jing selecting crude drugs with winnower and gravity preparation, select certified seed；
S3, medicine process, take appropriate cotton seeds and are put in the treatment fluid containing 0.2%KCl and 150mg/L gibberellins, 28
Soak seed 8 hours at DEG C, then seed is taken out；
S4, seed soaking pre-treatment, cut off an osculum by the micropylar end of seed, make radicle expose 2～3mm, should not be by radicle
Cut off；
S5, seed soaking, by the seed after clip with 53～56 DEG C of water seed soakings, when water temperature is down to 39～41 DEG C, are placed in 38
Soak seed in～42 DEG C of incubators or incubator；
S6, culture, will be laid in culture vessel after culture paper water-soaked, and the cotton seeds after step S4 is soaked seed are with list
On the culture paper that layer form is placed in, the culture paper for covering one thereon again with water-soaked but not dripping puts 28～32 DEG C of cultures
Cultivate in case；
S7, bud is looked into, carry out looking into bud after culture, choose normal chitting piece.
Preferably, lint method described in step S1 includes：
S11, to the dilution heat of sulfuric acid of high residual fine hair seed spray mass ratio 12%, and add the ten of final concentration mass ratio 5%
Sodium dialkyl sulfate；
S12, stir, increase the acid soak time；
High residual fine hair seed after S13, immersion increases drying roller inlet temperature to 220～245 Jing after centrifuge takes off and does
DEG C, mix the time 75～90 minutes, form light seed by grinding sassafras cylinder, the cylinder rolling of mill sassafras with low speed；
Preferably, described in step S2, seed choosing method is：By the cotton seeds after step S1 lint from eminence downwards with certainly
Thrown down by falling bodies mode, will weight debris, mature seed and immature seed by horizontal wind-force during free-falling
And light debris are separated.
Preferably, the seed soaking time in step S5 is 25～35min.
Preferably, in the incubation of step S6, the filter paper that covers on seed daily water spray, to soak filter paper but not
Drip for standard.
Preferably, normal chitting piece described in step S7 is 2 times of radicle and hypocotyls total length more than seed length,
The seed for having main root and hypocotyls disease-free.
The invention has the advantages that：
(1) with batch cotton seeds, by the seed of this method process, the bud rate of bud rate 5%～8% can be improved；
(2) with batch cotton seeds, by the seed of this method process, germinating energy can emerge 93% for 5 days, improve 4 hundred
Branch；
(3) with batch cotton seeds, by the seed of this method process, sprout quality is significantly improved, fresh and alive strong shape, vigor
By force；
(4) with batch cotton seeds, by the seed of this method process, Phase ofsprouting is improved, and Seedling is uniform in size.
