Embodiment 1

[0012] Embodiment 1, a kind of method prolonging the storage time of paddy seed, carries out following steps successively before carrying out storage:

[0013] 1) First, soak the rice seeds in pure water according to the ratio of 20g rice seeds / 100ml purified water, and then put the rice seeds together with the purified water into a sealed polyethylene plastic bag; the polyethylene plastic bag is required to be able to withstand the following High pressure in step 2).

[0014] 2), pressure is applied to the inner chamber of the sealed polyethylene plastic bag, so that the rice seeds positioned in the above-mentioned sealed polyethylene plastic bag are processed for 10 minutes under a high pressure of 200 MPa (that is, the holding time is 10 minutes).

[0015] 3), the paddy seed after the high-pressure treatment of step 2) gained is optionally carried out hot-air drying in any of the following ways:

[0016] Drying at 30°C until the moisture content of the rice seeds is 12%; ...

Embodiment 2

[0019] Embodiment 2, a kind of method prolonging the rice seed storage time, the high pressure of 200MPa in step 2) is changed into the high pressure of 400MPa, and all the other are with embodiment 1.

Embodiment 3

[0020] Embodiment 3, a kind of method prolonging the rice seed storage time, the high pressure of 200MPa in step 2) is changed into the high pressure of 600MPa, and all the other are with embodiment 1.

Abstract

The invention discloses a method for prolonging the storage life of rice seeds, wherein, the following steps are performed in sequence before storage: (1), the rice seeds are soaked in purified water, and then the rice seeds and purified water are put in a sealing container together; (2), the rice seeds in the sealing container are processed for 9 to 11 minutes under the high pressure ranging from 200 to 600 Mpa; and (3), the obtained rice seeds that are processed through high pressure are dried through hot air, and the drying temperature ranges from 30 to 60 DEG C until the water content of the rice seeds ranges from 11.0 to 12.5 percent. The rice seeds that are processed by adopting the method can still achieve higher germination percentage after being stored for a long time.

Description

technical field [0001] The invention relates to a method for prolonging the storage time of rice seeds, which belongs to the post-harvest treatment technology of rice seeds. Background technique [0002] During the storage of rice as seeds, due to physiological reasons, the germination rate of the seeds gradually decreases with the increase of storage time. This makes the paddy as seeds can not be stored for a long time, virtually increases the cost of seeds, which is not conducive to the departments and enterprises engaged in seed sales, nor to farmers who buy and use seeds. Therefore be necessary to develop a kind of post-harvest paddy seed treatment process, can improve the storage capacity of seed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for prolonging the storage time of rice seeds; the rice seeds treated by the method can still have a higher germination rate after long-term storage.
