Cause the corn underproduction, and disease is excessive.
The content of the invention：
The technical problems to be solved by the invention are to provide a kind of technological process simply, and corn seed can be prevented to go bad
The low-temperature storage method of the corn seed of germination.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of low-temperature storage method of corn seed, it is characterised in that：Comprise the following steps：
1) collect or purchase corn seed and sorted, with full grains, disease-free corn seed is advisable, and goes
Except internal impurity；
2) corn seed after sorting is carried out into preliminary precooling in time, forecooling method is that corn seed is all put into temperature
To be stored 24 hours in 1-2 DEG C of freezer.
3) by the corn seed after preliminary precooling by air-drying or directly drying, and once sorted again, gone
Except useless seed；
4) corn seed after precooling in step 3 is carried out into sterilized sprinkling using using 100mg/L stable chlorine dioxide disinfectants
Disinfect；
5) corn seed after being processed in step 4 is sealed in being put into the high-quality moisture-inhibiting bag that wall thickness is 0.025-0.05mm in batches
Mouthful；
7) storehouse is carried out disinfection and is closed 1-2 days using disinfectant powder, then clear away disinfectant powder, and it is small to open ventilative 3
When；
Described disinfectant powder passes through：Quick lime 20-30 parts, 8-10 parts of solid-state potassium permanganate, 10-20 parts of lemon peel powder,
Chlorine dioxide 2-4 parts, calcium hypochlorite 3-5 parts is ground into after powder to compound and forms.
8) corn seed sealed in step 5 is placed in sterile-processed freezer in step 7；
9) close freezer and adjust to 1-3% oxygen content in freezer, carbon dioxide content is adjusted to 5-7%；
10) temperature of ice house is adjusted to 3 DEG C -4 DEG C by packed corn seed precooling 48 hours again, then storehouse temperature drop to 1 DEG C -
2 DEG C are continued precooling 24 hours, and constant refrigeration 10 hours after being finally down to -1 DEG C -0 DEG C again will be protected during refrigeration every 2-3 hours
Fresh bag opens bag and corn seed is gently stirred and 20 minutes envelopes again are stood；
11) corn seed in step 10 after refrigeration is fitted into incubator and is sternly sealed using adhesive tape；
12) by storehouse temperature control at 0-1 DEG C, constant temperature storage, and it is small that a storehouse ventilation 3-5 was carried out every 2 months
When, until the coming year takes out using.
The beneficial effects of the invention are as follows：Present invention determine that being conducive to the suitable condition of the storage of corn seed, it is ensured that
Rational temperature, humidity, gas componant in storehouse, solve dehydration, aging, yellow, germination, corruption during corn seed storage
Rotten fast problem, improves the storage time of corn seed and will not destroy quality, has promoted the industry development of corn seed, carries
High added value, it is ensured that the high yield of corn seed, improves income.
