Problems solved by technology

[0005] It has been reported that dry, anaerobic conditions enhanced the viability of primed celery seeds, whereas dryness alone (using drying beads) or anaerobic conditions alone (addition of deoxidizers) did not improve seed viability
The former only under dry conditions, the seeds will still oxidize and age; the latter only under anaerobic conditions, due to the moisturizing agent contained in the deoxidizer, increases the moisture content of the seeds, so that even in an anaerobic environment, the seeds cannot be improved. vitality

Embodiment 1

[0051] Determination of the amount of water released by the deoxidizer in the storage environment: put the known weight of dry silica and deoxidizer in a 194mL airtight glass bottle, and use the same container at the same time, add the same weight of dry silica, but do not add Deoxidizer But as a control container, the deoxidizer is iron powder deoxidizer (wonderkeep RP, Ageless ZPT, Ageless Z). Three days later, open the container and immediately measure the weight of the dry silica in the control container and the treatment container. The weight difference between the two is the amount of water released by the deoxidizer during the deoxidation process in a 194mL sealed glass bottle.

[0052] Place the seeds and silica at the desired water activity and storage temperature (20°C, 30% relative humidity) to equilibrate for a period of time. Silica needs to be equilibrated in flowing air for more than 5 days. The number of days for seed equilibration depends on the size of the see...

[0066] Determination of the amount of water released by the deoxidizer in the storage environment: put the known weight of dry silica and deoxidizer in a 194mL airtight glass bottle, and use the same container at the same time, add the same weight of dry silica, but do not add Deoxidizer But as a control container, the deoxidizer is iron powder deoxidizer (wonderkeep RP, Ageless ZPT, Ageless Z). Three days later, open the container, and immediately measure the weight of the dry silica in the control container and the treatment container. The weight difference between the two is the amount of water released by the deoxidizer during the deoxidation process of the 194mL sealed glass bottle.

[0067] Seeds and silica gel are placed in the desired water activity and storage temperature (20°C, 15% relative humidity) to balance for a period of time. Silica needs to be balanced in flowing air for more than 5 days. The number of days for seed balance depends on the size of the seed. Af...

Abstract

The invention relates to the technical field of seed storage, in particular to a method of keeping low oxygen storage of seeds and invariability of water activity of seeds. The method comprises the following steps: putting treated seeds, a desoxidant and a compound water activity regulator in a storage container; and sealing the container. The method is simple to operate and low in cost. A low-temperature and low-humidity storage storehouse and a storage cabinet are not established, so that the method is energy-saving and good in economical benefit. The seeds can be stored at constant temperature, and in the seed storage process, the water activity is kept unchanged, so that the seed quality is ensured. The method is suitable for storing vegetable seeds, cereal seeds and bean seeds as wellas pelletized seeds and priming seeds.

Description

technical field [0001] The invention relates to the technical field of seed storage, in particular to a method capable of maintaining a low-oxygen storage environment for seeds at room temperature and keeping the water activity of the seeds unchanged during the storage process. Background technique [0002] Seeds are stored for a period of time from harvest to sowing. Seed storage is the use of reasonable storage equipment and advanced storage technology to artificially control storage conditions, minimize the change of seed quality, and most effectively maintain the vigorous germination and vitality of seeds, so as to ensure the seed value of seeds. [0003] Seed storage is one of the important factors affecting seed quality. Seed aging during storage may lead to delayed seed emergence, eventually resulting in abnormal seedlings, or even failure to emerge. Seeds stored in gene banks may lose genetic diversity due to seed aging. The lifespan of seeds changes with the stor...
