As a big country in agricultural production, the quality of seeds will directly affect the production of agriculture and the interests of farmers. The storage technology of seeds is also increasingly important. In recent years, the construction of seed deposits has also become increasingly important. Because the seed's shelf life is the same as that of general agricultural products, its moisture content is inseparable from the temperature and humidity of the storage environment. Therefore, the seeds should be dried before entering the store, and the seeds should be kept at the corresponding temperature and humidity.
The safe storage period for general seeds is:
1. Long-term storage of seed cold storage: The temperature in the storage tank is below -18°C, and the relative humidity in the storage tank should be less than 50%. The storage period is 50 years.
2. Cold storage of seed in mid-term storage: The storage temperature of the reservoir is -4 to 0°C and the relative humidity is less than 50%. The storage period is 15 years.
3. Short-term storage of seed cold storage: The relative humidity of the library at 10°C is less than 75% and the storage period is 3 years.
Based on the above data, it can be seen that the lower the temperature and relative humidity in the seed storage, the longer the safe storage period of the seed. Therefore, the design of seed storage is not only to control the temperature of the reservoir, but also to control the relative humidity. Through a large number of seed storage practices in low-temperature seed storage, the accumulated grain seed storage technologies include: the most common storage technologies, low-temperature and moisture-proof storage, and the seeds that have been selected and dried to a level below the safe moisture content are packed into sealed moisture-proof metal cans. Or aluminum foil composite film bag, and then it is stored under low temperature and dry conditions. Canned, aluminum foil composite film bags can also be evacuated into a vacuum or semi-vacuum state when sealed to reduce the oxygen content in the container, so that the storage effect is better.
