Embodiment 1

[0021] A kind of corn seed storage method, comprises the steps:

[0022] S1. Natural drying: the corn seeds sown and harvested in 2012 were selected and placed in the sun for drying, and the corn seeds were combed and turned every 2 hours, and the sun exposure time was 4 hours a day for 5 consecutive days;

[0023] S2. Initial screening: use machinery to remove impurities such as broken grains, dead leaves and grass seeds, and select corn seeds that meet the specified standards of quality and maturity;

[0024] S3, carbon dioxide treatment: place the corn seeds treated in step S2 in an airtight container, inject carbon dioxide into the container, and make the concentration of carbon dioxide in the container 80%, and place it for 15 days;

[0025] S4, sterilization and deinsectization: irradiating the corn seeds treated in step S3 with ultraviolet rays for 10 hours;

[0026] S5, secondary screening: screen the corn seeds treated in step S4, pick out corn seeds with mildew, ins...

Embodiment 2

[0035] A kind of corn seed storage method, comprises the steps:

[0036] S1. Natural drying: the corn seeds sown and harvested in 2012 were selected and placed in the sun for drying, and the corn seeds were combed and turned every 4 hours, and the sun exposure time was 6 hours a day for 3 consecutive days;

[0037] S2. Initial screening: use machinery to remove impurities such as broken grains, dead leaves and grass seeds, and select corn seeds that meet the specified standards of quality and maturity;

[0038] S3, carbon dioxide treatment: place the corn seeds treated in step S2 in an airtight container, inject carbon dioxide into the container, and make the concentration of carbon dioxide in the container 95%, and place it for 10 days;

[0039] S4, sterilization and deinsectization: irradiating the corn seeds treated in step S3 with ultraviolet rays for 12 hours;

[0040] S5, secondary screening: screen the corn seeds treated in step S4, pick out corn seeds with mildew, ins...

Abstract

The invention provides a maize seed storing method, and relates to the technical field of storage of plant seeds. The method comprises the following steps: naturally drying; primarily screening; treating with carbon dioxide; sterilizing and disinfesting; secondarily screening; manually drying; treating a warehouse; storing; performing the storing management. The method is simple and convenient to operate; the seed storage time can be effectively prolonged on the premise that the seed storage quality is ensured, so that the overall quality of seeds can be improved, and the seed germination rate can be ensured; meanwhile, the maize seed storing cost can be greatly reduced; in addition, ventilation treatment for the seeds at special time is avoided, and thus the cost can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of plant seed preservation, in particular to a corn seed storage method. Background technique [0002] Corn is one of the important food and industrial raw materials needed by the world's population. It is also one of the most widely distributed food crops in the world. The planting area is second only to wheat and corn, ranking third. And today's world and our country all attach great importance to improving the quality and output of corn seeds, and the preservation method of present corn seeds makes the yield and quality of corn not as good as one generation, and the key factor is the quality of seeds. During the preservation of seeds, neither the sun is too dry nor sealed storage, the cells in the seeds will dehydrate and die if the sun is too dry. In addition, seeds, like plants, also need to breathe, and mainly absorb oxygen, and the seeds will die of asphyxiation if they are sealed. In the prior art,...
