Description
Technical field
The invention belongs to Rice Cropping technical fields, and in particular to a method of release seed rice dormant period.
Background technique
Seed dormancy is vital seed due to embryo or kind shell, cannot still be sprouted under suitable environmental condition
The phenomenon that hair.Suspend mode is a kind of adaptability for resistance poor environment that plant obtains in long-term system growth course, is to adjust
The effective ways of Best Times and spatial distribution that seed is sprouted.Crop seeds with hibernation feature are in areas of high temperature and rainfall
Spike sprouting can be prevented, the seed of certain desert plants can spend arid season with dormant state, with sprouting condition to be suitble to.
Seed rice by prolonged cold storage can all enter dormant period, and the seed rice stored is directly sowed, is greatly prolonged
The seedling-growing time of seed rice has been grown, while all having been had an impact to germination percentage and survival rate.Therefore, the seed rice stored prior to seeding will
It is handled, releases the dormant period of seed rice, shorten seedling-growing time.
Following several method breaking dormancy is generallyd use in production：1）Low-temperature treatment；2）It is dried；3）Exposure-processed；
4）Flushing processing；5）Mechanical treatment；6）Chemicals treatment.Although the above method can effectively release the suspend mode of seed,
Shorten the seed sprouting time, but also all there are some problems simultaneously.Such as low-temperature treatment and drying process, processing time are general
At one week or so, the time was longer；Exposure-processed rinses processing and mechanical treatment, and not only efficiency is lower, while how in treatment process
It is easy that seed is caused to damage, will lead to seed death when serious；Chemicals treatment, when the chemical agent used is handled, medicine
Concentration, dosage and the processing time of agent do not have specific index, it is not easy to grasp, be easy to appear deviation, cause effect poor.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of method for releasing seed rice dormant period is provided.
The present invention is achieved by the following technical solutions：
A method of seed rice dormant period being released, specific step is as follows：
1）Seed rice by storage is taken out, is laid in indoor ventilation, laying with a thickness of 1-3cm, ventilation process 2-5h, to
The surface of the seed temperature reaches room temperature；
2）Seed rice is put into 25-30 DEG C of warm water and is impregnated, water level did not had seed rice 1-2cm, soaking time 20-40min；
3）It is dried after seed rice after immersion is taken out, is put into container, helium will be passed through after container vacuum-pumping, between container is carried out
Having a rest property infrared radiation, every minor tick 30-50min irradiation is primary, and each irradiation time 10-20s irradiates 3-5 times；
4）After to be illuminated, seed rice is put into container, is added in buffer, liquid level did not had seed rice 5-8cm, then by container
It is put into 40-60 DEG C of water bath with thermostatic control, constant temperature impregnates 10-30min；
5）Seed rice after immersion is put into radiant bottles, argon gas is passed through after air is detached, vacuumize process is carried out, makes radiant bottles
Middle pressure is -50--100Kpa, and radiant bottles are placed in plasma generator, is placed in the centre at radio frequency the two poles of the earth, opens radio frequency electrical
Source, discharge power are set as 300-500kw, and seed rice is made to handle 10-30min under the plasma form that argon gas is formed；
6）Processed seed rice is put by potassium nitrate, calcium nitrate, boric acid, magnesium sulfate, ammonium phosphate according to 1：1：2：2：3-1：3：
3：4：20-50min is impregnated in the nutrient solution of 4 weight proportion preparation.
Preferably, a method of releasing seed rice dormant period, wherein the preparation method of buffer is as follows：
1）Take the NH4NO3 of the NaCl solution of 20-30%, the NaOH solution of 20-40%, the NH4Cl solution of 10-20% and 20-30% molten
Liquid is according to 1：2：2：3-1：3：3：4 weight proportion prepares conductance solution；
2）1-3 parts of catalase are taken, 2-5 parts of superoxide dismutase, is added 1）In conductance solution in, oscillation stirring after i.e.
A kind of buffer solution can be made.
The present invention has the following advantages that compared with prior art：
A kind of method releasing seed rice dormant period provided by the invention, laying is led to indoors after the seed rice after storage is taken out
Wind processing, can go back seed rice temperature and slowly be promoted, avoid the temperature difference is much from causing seed rice cellular damage, surface temperature is restored to room
The seed rice of temperature is put into warm water and is impregnated, and after absorbing moisture, kind skin expansion softens seed, the oxygen being dissolved in water with
Hydrone enters cell, promotes the activation of enzyme in seed, to restore the physiological activity ability of seed rice.Seed rice progress gap is had a rest
Infrared radiation promotes cell tissue temperature to increase under infrared radiation, accelerates cell liquid flowing, enhances newly at metabolic capability, mention
High tissue cell activity and cytothesis ability.After the buffer of seed rice preparation is impregnated, seed rice surface is made to contain a large amount of trips
From zwitterion, seed rice is fitted into radiant bottles, is evacuated to -50--100Kpa after being filled with argon gas, be then placed within etc. from
In electronic generator, the argon gas in bottle is made to form plasma form, under the action of argon plasma, accelerates seed rice surface yin-yang
The movement of ion forms closed circuit, promotes cell flowing, while seed rice surface being made subtle crackle, surface duct number occur
Amount increases, aperture increases, and intercellular space between cells increases, and improves seed rice to the absorbability of nutrient.
Method provided by the invention can accelerate the releasing of seed rice dormant period, shorten germinating time to 1-2d, improve germination
Rate and survival rate greatly improve the yield and quality of rice to 98.5% and 97.2%.
