Description
Technical field
The present invention relates to vegetable seeds Techniques of preserving field, and in particular to a kind of rice paddy seed storage method.
Background technology
Paddy rice originates in Tropical Asian, after China widely plants, gradually travels to all over the world.According to different point-scores,
Paddy rice can be divided into long-grained nonglutinous rice and japonica rice, early rice and middle late rice, glutinous rice and non-glutinous rice.Paddy rice tie after the grain of rice shells claim rice or
Rice, nearly half population, is food all with rice in the world.The eating method of rice is varied, there is rice, congee, rice cake, rice
Cake, rice noodles etc..Paddy rice can also make wine, refine sugar and make the raw material of industry in addition to edible, and rice husk, rice straw also have many use.Therefore
It can be said that paddy rice is the basic staple food of people, the plantation of paddy rice and results are also to weigh the major criterion of Agricultural Level.
For paddy rice, the quality of rice paddy seed will directly affect growth and the yield of paddy rice.After rice paddy seed is harvested,
Into storage stage, if not using appropriate method to be taken care of, seed easily generates heat, goes mouldy, being corroded by worm and mouse sparrow, so that
Lose Seed practical value.Method according to science is in safe keeping, and seed can be made to keep vigorous vitality, even if in bad ring
Under the conditions of border, also can safely reach a standard, germination percentage will not be influenceed.
Conventional seed storage method packs storage practice, suffocating treatment insect prevention, Storage in cold bank technology etc., but
So far, still without a set of effective practical technique code extensive use, percentage of seedgermination also will year by year decline, pass every year
Subtract and then lose the effect of seed, the deposit of seed there is also loss problem so country prepares against natural disasters.Therefore protected by different approaches
Hold and even improve seed vitality, extend seed longeivity, be not only a problem highly inquired into, Er Qie biologically
There is Great significance in agricultural production.
The content of the invention
Germination percentage can be kept not have rice paddy seed longer-term storage in order to solve the above technical problems, the present invention provides one kind
There is significantly reduced rice paddy seed storage method.
The present invention is adopted the following technical scheme that：
A kind of rice paddy seed storage method, comprises the following steps：
S1, in good time harvesting：10~15d after the maturation of rice paddy seed field, when seed moisture content is up to 20~24%, harvests；
It is generally acknowledged that 10~15d after the maturation of rice paddy seed field, the yellowing of setting percentage 95%, the branch stalk on cob top 1/3
Withered, fringe base portion is changed into yellow, and full fringe outward appearance chlorosis, leaf turns yellow, you can harvest.Harvest time can not be too early, in order to avoid cause into
Ripe degree is inadequate；Otherwise embryo does not develop normal size also, and potential germinating capacity does not become normal, and the nutrition of Interior Seed solubility is also
Insoluble nutrients is not fully converted into, the organized enzyme in seed is not being dried fully still not at passivation protection state, seed
In the case of, vigorous respiration is still carried out, nutrition is consumed, so that the viability of seed declines；But, can not
It is undue to postpone harvest time.Due to being maternal hybrid rice seeds particularly with 46A sterile lines without obvious rest period, by
In splitting, clever degree is heavier, is harvested not in time after maturation, if meeting field high-temperature high humidity climate, Seed sprouting is sprouted, so
Seed vigor can be made low on the contrary, germination percentage reduction.
S2, natural drying：The rice paddy seed of results is placed and is dried in the sunlight, every 2~4 hours to rice seed
Son carries out a combing and stirs, 6~8 hours daily Exposure to Sunlight time, continuous Exposure to Sunlight 3~5 days；
Direct deinsectization or artificial drying are avoided after paddy rice just harvesting, is dried again after should being dried under natural environment, this
Infringement of the sample to rice paddy seed is smaller.
S3, first screening：Using the flat grain of mechanical removal, dead leaf and grass-seed impurity；
S4, carbon dioxide treatment：The rice paddy seed processed through step S3 is placed in closed container, is injected in container
Carbon dioxide, and cause container in carbon dioxide concentration be 80%~95%, place 10~15 days；
S5, sterilization and disinfestation：The rice paddy seed spray concentration that will be processed through step S4 be 60% cartap, after shone with ultraviolet
Penetrate 10~12 hours；
Preservation of the insect pest to seed in seed storage is fatal harm, and the present invention is using injecting carbon dioxide, sprinkling
Insecticide and ultraviolet irradiation technical scheme, by seed as oxygen-free environment in, the worm's ovum in seed etc. can be made to lose activity,
Insecticide and ultraviolet irradiation can kill worm or mould in seed etc..
S6, sealing irradiation：The rice paddy seed processed through step S4 is placed in clear glass seal box carries out day illumination
Penetrate 6~8 hours；
S7, postsearch screening：The rice paddy seed processed through step S6 is screened, choose have go mouldy, the water of pityriasis simplex, mildew
Rice, remaining carries out step S8；
S8, artificial drying：Seed is put into baking box, is dried to rice paddy seed moisture content and is reached 11%~12%, stopped
Dry, packed using woven bag, be put into warehouse low temperature storage；
S9, storage：Low temperature is stored during warehouse will be put into by the rice paddy seed of step S8；
S10, inspect periodically：24h monthly is exhausted to warehouse 1 time.
Preferably, warehouse is carried out disinfection before rice paddy seed is put in storage, the measure of use is to use 85% enemy to oppose
Fear missible oil presses 80~120mg/m2Spraying disinfection is carried out, is sealed 48 hours, seed can be put in storage after divulging information 24 hours.
Preferably, the method for artificial drying is in the step S8, seed is put into after baking box and is set 30 DEG C of temperature and is entered
Row drying, is dried less than being warming up to 40 DEG C after 20%, after the moisture content of rice paddy seed until rice paddy seed moisture content is dropped to
15%, continue to reach 11%~12% using 45 DEG C of freeze-day with constant temperature to rice paddy seed moisture content, stop drying, in artificial drying
In sub-processes, usually because temperature adjustment is improper or abnormal high temperature occurs in heating inequality, high-moisture seed is caused to occur secondary
Resting state, therefore the present invention is unique is dried using first natural environment, then the progressively artificial technical scheme for heating up, it is relatively existing
Technology, can more reduce the phenomenon of seed secondary dormancy.
Preferably, the method for being stored in the step S9 is that, by the temperature control in warehouse at 10~12 DEG C, humid control exists
15~20%, stacking mode is wall stacking, and from 30~35cm of wall, heap 5~8m high keeps spacing between pile and pile, every with layer
Ventilating duct, bilevel ventilating duct is stayed to stagger every 3~4 woven bags, seed is lived organic object, there is breathing energy
Power, the too high meeting of humidity is rotten or even mildew and rot in a certain temperature conditions.Temperature is too high, and seed respiration is vigorous, can be excessive
The nutrition of consumption itself storage, reduces germination percentage.Therefore the temperature and humidity in warehouse is most critical factor, temperature mistake in storing
Height, seed breathing is vigorous, and humidity is too high, and seed easily rots, therefore by temperature and humidity control in optimum range.
The packaging of seed is mainly Polywoven Bag 50kg packagings, should not use gunnysack or bulk storage, because of moistureproof, insect prevention and ventilative
Property is poor.Putting should not lean on wall too near, from 30~35cm of wall, should not be too wide oversize, and it is more satisfactory per pile 3m × 5m；Will between pile and pile
Ventilating duct and pavement are stayed, so that air circulation and keeper enter observation, detection, 50~60cm is advisable；With layer every 3~4
Individual woven bag stays ventilating duct, bilevel ventilating duct to stagger；The ventilating duct of 40~50cm should be stayed between pile and ceiling；Per a collection of
It is secondary to hang up properly label, carry out original record.
Beneficial effects of the present invention：
Compared with prior art, this invention ensures that germination percentage is not less than 90% at seeding time, seed management is effectively reduced
Cost, effectively alleviates the autumn harvest season artificial nervous contradiction nervous with harvest time, it is to avoid artificial to ted cause a large amount of artificial
Waste, be prevented effectively from existing threshing ground is not enough and a large amount of seeds cannot be dried caused by weather reason contradiction and harvest time short
The contradiction long with drying time is dried.The storage time of rice paddy seed can reach 4~5 years, meet the production of Seed enterprises
Needs, the reduces cost of maximum possible and the quality of guarantee seed, with good practicality.
