Description
Technical field
The present invention relates to corn seed storage technology field, in particular to a kind of store method of corn seed.
Background technique
Corn is to be distributed one of widest cereal crops, growing surface in the world as a kind of important cereal crops
Product is only second to wheat and rice two occupies third position, is even more to have evolved into the first big industrial crops in China.Therefore, pay attention to and
The quality and yield for ensureing corn crop production have very important meaning to grain security and economic development.
One of quality and the key of yield for improving corn crop production are exactly the preservation carried out to corn seed.Maize seed
The quality that son saves directly affects the vitality of corn seed.In the preservation process of seed, can neither shine it is too dry not yet
Can be sealed, solarization it is too dry, the cell in seed, which can be dehydrated, dies；Exhale corn seed can not
It inhales, thus seals seed to cause breath and dead.
In the prior art, general to require to be drying, low temperature, ventilation for the preservation of corn seed.But because of southern humidity
Weather easily makes seed mildew or advance germination, to seriously affect seed quality.Thus, it is not suitable for south and waits flush
The corn in area saves.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of store method of corn seed, the ground that is especially suitable for that there was dampness in the air
Preservation of the area for corn seed.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is as follows:
A kind of store method of corn seed, comprising the following steps:
(1) corn seed for selecting high-quality germ plasm resource carries out sprinkling sterilization treatment with bactericidal agent, is then placed in gibberellin
0.5-3h is impregnated in solution, is drained；
(2) corn seed after above-mentioned drain is coated processing: adds 10wt%- in the seed coat agent of corn seed
The chitosan of 20 wt% is coated processing to corn seed after mixing, then dry under the conditions of 25-50 DEG C of temperature
It is 7%-13% to moisture content；
(3) corn seed after drying is placed in temperature condition is 1 DEG C -18 DEG C, and relative humidity is 60% or less seed bank
Interior preservation.
Preferably, the chitosan of 15wt%-18wt% is added in the seed coat agent of corn seed in step (2).
Preferably, the concentration of the Gibberellins solution is 40-90mg/L.
Preferably, the bactericidal agent is alcohol, carbendazim, thiophanate methyl, 0.5% mercury chloride either gram bacterium
It is red.
Preferably, being also added with dodecyl sodium sulfate in Gibberellins solution described in step (1).Dispersed by addition
Agent dodecyl sodium sulfate can promote absorption of the corn seed to gibberellin, improve the vigor for saving seed.
Preferably, the additive amount of the dodecyl sodium sulfate is the 0.5%-3% of Gibberellins solution weight.
The beneficial effects of the present invention are:
(1) store method of corn seed of the present invention carries out sterilization treatment to corn seed by fungicide first,
Eliminate the influence that microorganism saves corn seed；And by immersion of the corn seed in Gibberellins solution, so that beautiful
Rice seed still has higher vigor after the preservation of long-term storage；Particularly, kind clothing of the present invention in corn seed
The chitosan that 10%-20% is added in agent, is then coated processing to corn seed, by the process, so that corn seed
The long-term preservation of corn seed is realized in southern humidity larger area.Corn seed is saved using this method, can be widely applied to
The higher area of humidity.
(2) simply, conveniently, each raw material is easy to get operation of the present invention, and high treating effect, processing cost is low, and market prospects are good, tool
There is biggish application value.
