Problems solved by technology

However, freeze-drying or silica gel drying is costly and is only suitable for germplasm resource preservation institutions and some related laboratories when saving a small amount of seeds
Therefore, although the super-dry seeds of Korean pine can greatly prolong the storage time and are of great significance, at present, in forestry production, there is still no production technology for the storage of super-dry seeds of Korean pine. Difficult to master in production

Embodiment 1

[0024] Example 1: The production technology of ultra-low moisture content Korean pine seeds processing and storage, including the following steps in sequence: 1) Seed inspection: the moisture content of Korean pine seeds is 18%. After necessary cleaning and removal of impurities, it was stored in the above-ground warehouse (November to April in Harbin) for five months. After inspection, the viability was 75%.

[0025] 2) Natural drying: On April 17, the weather was fine, the temperature was about 25°C, and the relative humidity was below 65%. Continue artificial drying and blast drying at 40°C-50°C to reduce the water content to 6%. After sampling inspection, the obtained ultra-low water content Korean pine after rewetting treatment has a viability of 76%.

[0026] Packaging: Immediately after drying, pack it into an iron drum and seal it.

[0027] Storage: After one year of storage at room temperature in the above-ground warehouse, after sampling inspection, the ultra-low mo...

Embodiment 2

[0028] Example 2: The production technology of ultra-low water content Korean pine seeds processing and storage, including the following steps in sequence: 1) Seed inspection: the water content of Korean pine seeds is 21%. After necessary cleaning and removal of impurities, it was stored in the above-ground warehouse (November to April in Harbin) for five months. After inspection, the viability was 80%.

[0029] 2) Natural drying: On April 20, the weather was fine, the temperature was about 24°C, and the relative humidity was below 65%. Continue to artificially dry and mix with calcium chloride to reduce the water content to 5%. After sampling inspection, the obtained ultra-low moisture content of Korean pine seeds was 79% viability after re-humidification.

[0030] Packaging: Immediately after drying, pack it into an iron drum and seal it.

[0031] Storage: After one year of storage at room temperature in the above-ground warehouse, after sampling inspection, the viability ...

Embodiment 3

[0032]Example 3: The production technology of ultra-low water content Korean pine seeds processing and storage, including the following steps in sequence: 1) Seed inspection: the water content of Korean pine seeds is 20%. After necessary cleaning and removal of impurities, it was stored in the above-ground warehouse (November to April in Harbin) for five months. After inspection, the viability was 85%.

[0033] 2) Natural drying: On April 20, the weather was fine, the temperature was about 24°C, and the relative humidity was below 65%. Continue to add calcium chloride to mix, the water content is reduced to 6%. After sampling inspection, the obtained ultra-low moisture content of Korean pine seeds was 83% in viability after rewetting treatment.

[0034] Packaging: Immediately after drying, pack it into an iron drum and seal it.

[0035] Storage: Stored at room temperature on the ground floor for 3 years, after sampling inspection, the viability of the ultra-low water content...

Abstract

The invention provides a production method for processing and storing Korean pine seeds. The Korean pine seeds with a water content of 15%-25% are used as materials and dried to obtain Korean pine seeds with ultra-low water content; the Korean pine seeds have ultra-low water content The amount of water is 5%-7%. According to the production method for processing and storing Korean pine seeds of the present invention, the water content of the produced Korean pine seeds is 5%-7% without significantly affecting its viability, and the production cost is low. Stored in airtight conditions at room temperature or in caves for a long time, the viability decreases slowly.

Description

technical field [0001] The invention relates to a production method for processing and storing Korean pine seeds, belonging to the field of forest tree seed production and storage. Background technique [0002] Korean pine seeds have a certain lifespan limit. After harvesting, conventional natural drying of Korean pine seeds under normal storage conditions at room temperature, with the increase of storage time, the viability of Korean pine gradually decreased. Usually stored at room temperature for 1 year, the viability will be less than 60%, and the seeds will not germinate neatly, which is no longer suitable for forestry production. Therefore, Korean pine seeds should not be routinely stored at room temperature for a long time. Korean pine is suitable for 60-100 years of age; the yield is divided into large and small years, no natural disasters, three years of small harvests and five years of large harvests; resources are lacking; therefore, the harvested seeds are very p...
