Description
Technical field
The present invention relates to agricultural plant breeding technical field, in particular to a kind of storage method of corn seed.
Background technique
Corn is one of China's Three major grain crops, is occupied an important position in agricultural production, plants and is distributed in China
It is very wide.As the large area of hybrid corn seed uses, the corn seed of part Seed company production is often because storing improper storage
Seed vitality is caused to decline, Seed practical value reduces, and affects Seed enterprises income and agricultural production.
So storing feature according to corn seed, using reasonable stored manner, seed vitality is being kept, kind of an industry is promoted
Company increases business income, it is ensured that plays an important role on agricultural production security
The storage of seed refer to seed harvest after to sow before preservation process.During storage, it is desirable that ensure seed
Life rate and germination percentage, prevent seed mildew, damage by worms, keep viability, high activity, purity and the purity of seed, be
The germplasm resource of agricultural production offer high quality.
The storing mode method of seed has significant impact to its viability, and the outstanding feature of seed vigor is that it is sprouted
Volatility, Germination performance and service life depend mainly on hereditary capacity, seed morphology structure and physiological activity, seed quality and storage
Condition.
It is the most significant with the influence of the water content of seed and reserve temperature, humidity etc..Seed is first carried out before seed storage
It is preferred that dry and disinfection；Ventilation is paid attention to after storage, moisture-proof, insect prevention, keeps constant low temperature.
Corn seed is a kind of caryopsis, and embryo is big, and son is real to be wrapped in by tough and tensile pericarp.These forms of corn seed
Feature determines that it stores feature.Maize At Embryo is big, and breathing is vigorous, is easy heated corn seed in cereal crop seed,
Belong to big semina, Maize At Embryo accounts for the 1/3 of entire seed volume, accounts for the 10%~12% of a weight, tissue looseness, containing more
Protein, fat, soluble sugar, respiratory capacity are big.
Additionally, due to more hydrophilic group is contained in embryo, thus seed embryo is stronger than endosperm water imbibition, under similarity condition,
Much bigger than other Cereal seeds of the respiratory intensity of corn seed, also his more other Cereal seeds are easy during storage
Fever.
Maize At Embryo is subject to entomophthora and causes harm.Maize portion it is full of nutrition, solable matter is more, microorganism adhesion amount compared with
More, after the moisture absorption of embryo portion, at a suitable temperature, mould easy to breed goes mouldy, and mildew is mould and aspergillus mostly.Furthermore
Embryo is also easy to as sitophilus zea-mais, ostomatid, the pest damages such as meal moth He Gu Du.
Maize At Embryo is easy rancid.The corn seed fat content overwhelming majority concentrates in embryo, containing in whole grain seed
77%~89% fat, the fatty acid value of embryo are consistently higher than endosperm, and embryo hygroscopicity is again relatively strong, therefore Maize At Embryo is easy
It is rancid, so as to cause seed vigor reduction.
The original moisture of corn seed is big, and maturity is uneven.Corn seed production is mainly in China northeast and northwest
Gansu Zhangye Prefecture, weather is cold when harvest, has bract outside corn ear in addition, cannot get drying sufficient day on plant
It is dry, so original moisture is generally large.Since corn seed moisture is higher, in China northeast, freeze injury easily occurs for the Northwest.
The maturity of corn seed is often also very uneven, and the top of same fruit ear is different with base portion pollination time, causes
Often maturity is poor for top seed.In addition corn content is high, and when threshing is easy to damage, so prematurity and the broken kernel of corn
More, this kind of seed is easier moisture absorption and the infringement by entomophthora.
In the prior art, the storage method of corn seed is mainly seasoning, and this method is simple and easy, operation side
Just, it but not can effectively prevent insect pest and the plague of rats, will affect germination percentage.Main reason is that excessively reducing respiration, influence
Seed normal viability, causes germination percentage to reduce.
Therefore it provides a kind of storage method of corn seed, simple and easy, mildew, insect pest incidence are low, and germination percentage
Height becomes those skilled in the art's urgent problem to be solved.
Summary of the invention
Technical problem to be solved by the present invention lies in provide a kind of storage method of corn seed, solve existing jade
Insect pest, mildew incidence are high in rice seed storage method, the low problem of germination percentage.
In order to solve the above technical problems, steps are as follows the present invention provides a kind of storage method of corn seed:
Step 1: the preferred label of seed: selection plant rising trend is good, resistant to lodging, germplasm full grains corn mature seeds
It is harvested, and indicates batch；
Step 2: sunning and removal of impurities: the preferred seed of harvest uniformly being tedded, and by soil, weeds, the particle in seed
Not full particle is picked and is cleaned；
Step 3: detection germination percentage: detecting the germination percentage of the corn seed of different batches, eliminates the unqualified batch of germination percentage
Seed；
Step 4: sterilizing: dry corn seed being sterilized；
Step 5: dry: high-grade maize seed being freezed into low temperature drying, and detects water content；
Step 6: seed pelleting: using fungicide thiram and pesticide imidacloprid allotment coating agent for seed to seed into
Row coating；
Step 7: storage: the seed after coating carries out low-temperature storage.
Preferably, the sterilizing in the step 4 is ultraviolet sterilization and ozone sterilization.
Preferably, the frozen drying temperature in the step 5 is -20 DEG C~-30 DEG C.

Method stores 3 months~15 years corn seed products.
In order to solve the above technical problems, invention further provides a kind of if aforementioned corn seed product is in corn planting
Using.
Beneficial effect of the present invention includes: that the method for the present invention is simple, and design rationally, using the method for the present invention saves maize seed
Son can reduce mildew and insect pest, improve germination percentage.The invention is simple and feasible, saves corn seed using the method for the present invention, mould
Variability is low, and germination percentage is high.
The present invention passes through preferred, the impurity elimination of seed, sterilizing, low temperature drying, the stringent control of seed pelleting and condition of storage
System, the sound assurance viability of seed.
The present invention chooses that plant growing way is good, superior corn seeds of full grains, removes impurity, low temperature drying controls water
Divide content, to reduce the respiration of seed.
The present invention removes the harmful microorganism and worm's ovum of the surface of the seed, reduces the generation of insect pest by sterilizing.Using seed
The form of coating plays a crucial role to the reduction of mildew rate, while further reduced the generation of insect pest；The mode of cryo-conservation
The respiration that seed is reduced in the case where guaranteeing normal required water content, keeps its viability.
