Device and method for prolonging seed storage time

Abstract

The invention discloses a device and a method for prolonging seed storage time and belongs to the field of seed storage. The device structurally comprises a bottle body, a bottle plug and separation layers. A bottle opening is arranged in the upper portion of the bottle body, the bottle plug is arranged at the position of the bottle opening, the separation layers are arranged in the bottle body, a middle hole is formed in the middle of each separation layer, a plurality of mesh holes are formed in each separation layer, a vent pipe is arranged on one side of the bottle plug, one end of the vent pipe is communicated with the inner cavity of the bottle body, and the other end of the vent pipe stretches out of the bottle plug. An oxygen sensor is arranged on the vent pipe on the outside of the bottle plug, a vent valve is arranged on the vent pipe between the oxygen sensor and the bottle plug, an air inlet pipe is arranged on the lower portion of the bottle body, and an air inlet valve is arranged on the air inlet pipe. Inert gas is utilized to cover seeds and delay the respiration action of the seeds to prolong the seed storage time accordingly. The device and the method have the advantages of being capable of effectively restraining respiration of the seeds, prolonging the seed storage time, delaying damage caused by oxidation respiration in the storage process of the seeds, effectively prolonging the service life of the seeds and the like.

Description

technical field [0001] The invention relates to the field of seed storage, in particular to a device and method for prolonging the storage time of seeds. Background technique [0002] When storing seeds and preserving germplasm resources, commonly used preservation methods include normal temperature drying method, low temperature drying method, and vacuum packaging method. [0003] The normal temperature drying method can save the seeds for 1-3 years, the low-temperature drying method can save the seeds for 3-5 years, the vacuum bag packaging method combines the normal temperature drying method and the low-temperature drying method, and the original storage time can be extended for another 1-2 years. Vacuum can quickly evaporate the residual moisture of seeds, which will damage the cell membrane system of seeds and even cause the seeds to die, which is especially prominent in seeds with high water content.
