Chinese invention patent application prospectus CN102047785A discloses a kind of method for storing corn seeds, comprises the steps: one, and the warehouse is processed; Two, the seed screening; Three, the storage life management.But in the method, step 1 is owing to using 80% dichlorvos to carry out disinfection, so make unavoidably the people worry the health problem of seed.And, in the method, requirement is ventilated in less than 40% situation in air humidity, and south is such as places such as Kweiyang, Wuhan, Guangzhou, and mean annual humidity is much larger than 40%, be in air humidity throughout the year and be higher than 40% even be higher than 50% situation, so must cause seed stuffy for a long time with the party's rule, thereby anoxic affects seed quality, as avoiding the generation of this situation, then need again to spend higher cost to reduce air humidity.
The content of invention
For addressing the above problem, the invention provides a kind of corn simple to operate, with low cost
The seed store method, and can be under the prerequisite that guarantees seed preservation quality, the Effective Raise seed holding time.
The present invention is achieved by following steps.
The store method of a kind of corn seed provided by the invention may further comprise the steps:
A kind of store method of corn seed is characterized in that: 2 ℃～15 ℃ of storehouse precooling temperatures; With ventilative gunnysack corn seed is wrapped; The corn seed of wrapping is positioned in the storehouse, stays one to surpass 0.2 meter wide passage between per two bags, every bag is liftoff to surpass 0.1 meter; Keep the storehouse temperature at 0～8 degree centigrade; Keep storehouse humidity 35%～60%.
Described storehouse precooling temperature is 10 ℃.
Keep the storehouse temperature at 2～6 ℃.
Keep storehouse humidity 45%.
Beneficial effect of the present invention is: simple, convenient, can be under the prerequisite that guarantees seed preservation quality, the Effective Raise seed holding time, and need not especially seed to be carried out special artificial seasoning processes, prevented in dry run the injury that may cause seed, improved the total quality of seed, guaranteed the germination rate of seed, greatly reduce simultaneously the cost of corn seed in the preservation process, and the processing of seed being ventilated when need not to select especially, greatly reduce cost.
Embodiment
The below further describes technical scheme of the present invention, but that claimed scope is not limited to is described.
2 ℃～15 ℃ of storehouse precooling temperatures; With ventilative gunnysack corn seed is wrapped; The corn seed of wrapping is positioned in the storehouse, stays one to surpass 0.2 meter wide passage between per two bags, every bag is liftoff to surpass 0.1 meter; Keep the storehouse temperature at 0～8 degree centigrade; Keep storehouse humidity 35%～60%.
Although the relative prior art of storehouse humidity is higher, and the packaging bag gas permeability of corn seed is better, but because the storehouse temperature is controlled under the lower temperature, so seed can keep good quality for a long time, and the moisture of cereal crop seed can anti--196 ℃ low temperature when 4%-6%, moisture is 14%, the low temperature of ability-20 ℃, when being increased to 17% such as moisture, can only anti--5 ℃ to 8 ℃ low temperature, because temperature is controlled at more than 0 ℃ among the present invention, so can be because of freezing so that seed cell is not impaired.Comparatively speaking, keep the storehouse temperature also lower than keeping storehouse humidity cost,
So in the southern high-humidity area, the method can effectively reduce cost.And the processing of seed being ventilated when need not to select especially, further reduced cost.
When the corn seed of wrapping is placed in the storehouse, owing to overhead certain distance is arranged, directly do not contact with ground, so in the preservation process, can effectively reduce surface temperature to the impact of seed.Simultaneously, owing between per two bag seeds distance is arranged, thus can guarantee well that also seed is kept in the suitable temperature and humidity, and ventilation is good, effectively avoids crossing the seed quality decline that high reason causes because of stuffiness, humidity.
Wherein, storehouse humidity generally can not be higher than 58%, and especially when being higher than 60%, the problem such as very easily occur germinateing, mouldy has a strong impact on holding time and seed quality.
Adopt this mode to preserve corn seed, but the high area of extensive use humidity only need lower cost to keep corresponding storehouse humidity and temperature, just can be implemented in when guaranteeing seed quality, makes the holding time more than 1 year.Simultaneously, because storage temperature is low, thus also can effectively avoid damage by disease and insect to the destruction of seed, thus greatly reduce the extermination of disease and insect pest cost in the seed preservation process.
