Problems solved by technology

[0004] Commonly used seed storage methods include sealed packaging storage methods, fumigation treatment to prevent insects, cold storage storage technology, etc., but so far, there is no set of effective practical technical procedures widely used, and the seed germination rate will also decrease year by year. The role of seeds, so there is also a loss problem in the national reserve of seeds for shortage

Embodiment 1

[0029] Wandao 199 is a new two-line hybrid late indica combination bred by the self-fertilized temperature-sensitive genic male sterile line 2301S used by the Rice Institute of Anhui Academy of Agricultural Sciences and the high-quality male parent 3401. On January 22, 2006, it was approved by the Anhui Provincial Crop Variety Approval Committee (approval number: Wanpinshen 06010511).

[0030] S1, timely harvesting: select the Wandao 199 rice seed field sown in 2012 to harvest 10-15 days after the rice seed field matures, and when the seed moisture reaches 20-24%;

[0031] S2. Natural drying: place the harvested rice seeds in the sun for drying, comb and flip the rice seeds every 2 to 4 hours, and expose to the sun for 6 to 8 hours a day for 3 to 5 days in a row;

[0032] S3. Initial screening: mechanically remove impurities such as shriveled grains, dead leaves and grass seeds;

[0033] S4, carbon dioxide treatment: place the rice seeds treated in step S3 in an airtight cont...

Embodiment 2

[0044] Huiliangyou 6 is a new hybrid rice combination bred from the self-fertile two-line male sterile line 1892S used by the Rice Institute of Anhui Academy of Agricultural Sciences and the mating group of Yangdao 6. In 2008, it passed the approval of Anhui Crop Variety Approval Committee (Wandao 2008003), and in 2012 it passed the national inspection.

[0045] S1, timely harvesting: select the Wandao 199 rice seed field sown in 2012 to harvest 10-15 days after the rice seed field matures, and when the seed moisture reaches 20-24%;

[0046] S2. Natural drying: place the harvested rice seeds in the sun for drying, comb and flip the rice seeds every 2 to 4 hours, and expose to the sun for 6 to 8 hours a day for 3 to 5 days in a row;

[0047] S3. Initial screening: mechanically remove impurities such as shriveled grains, dead leaves and grass seeds;

Abstract

The invention provides a storage method of rice seeds, relating to the technical field of storage of plant seeds. The storage method comprises the following steps: timely harvesting, natural drying, primary screening, treatment with carbon dioxide, sterilization and deinsectization, sealing irradiation, secondary screening, artificial drying, storage and periodic inspection. The storage method provided by the invention has the advantages that the storage time of the rice seeds can reach 4-5 years, the production need of seed enterprises is met, the cost is reduced to a greatest extent, the quality of the seeds is guaranteed and the practicability is good.

Description

technical field [0001] The invention relates to the technical field of plant seed preservation, in particular to a rice seed storage method. Background technique [0002] Rice is native to tropical Asia, and after being widely planted in China, it gradually spread to all parts of the world. According to different classification methods, rice can be divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice. Rice or rice is called rice or rice after the rice grains of rice are husked, and nearly half of the population in the world feeds on rice. Rice can be eaten in a variety of ways, including rice, rice porridge, rice cakes, rice cakes, and rice noodles. In addition to being edible, rice can also be used as industrial raw materials for wine making and sugar refining. Rice husks and rice straws also have many uses. Therefore, it can be said that rice is the basic staple food of people, and the planting and harves...
