Embodiment 1

[0020] 1. Seed selection: Pick the fully mature camellia oleifera fruit within 5 days after the frost, store the camellia oleifera fruit until the peel cracks, take out the seeds, and screen out the seeds that are large, plump and free from diseases and insect pests.

[0021] 2. Drying: After the screened Camellia oleifera seeds are spread out for 15 days, they are dried in a low-temperature and low-humidity dryer at a temperature of 5-10°C and a relative humidity of 15-20% to a moisture content of 7%.

[0022] 3. Packaging: Put the seeds into a PA+PE vacuum bag with a thickness of 12 wires, and vacuum seal it.

[0023] 4. Storage: Store Camellia oleifera seeds packed in sealed PA+PE plastic vacuum bags in a cold storage with a temperature of 0-4°C and a relative humidity of 45%.

[0024] The germination rate of Camellia oleifera seeds stored for one year was 96.2%.

Embodiment 2

[0026] 1. Seed selection: pick fully mature camellia oleifera fruits within 10 days after the frost, store the camellia oleifera fruits until the peel cracks, take out the seeds, and screen out the seeds that are large, plump and free from diseases and insect pests.

[0027] 2. Drying: After the screened Camellia oleifera seeds are aired for 15 days, they are dried in a low-temperature and low-humidity dryer at a temperature of 5-10°C and a relative humidity of 20-25% to a water content of 9%.

[0028] 3. Packaging: Put the seeds into a PA+PE vacuum bag with a thickness of 14 silk, and vacuum seal it.

[0029] 4. Storage: Store the Camellia oleifera seeds packed in sealed vacuum bags in a cold storage with a temperature of 0-4°C and a relative humidity of 50%.

[0030] The germination rate of Camellia oleifera seeds stored for 2 years was 94.8%.

Embodiment 3

[0032] 1. Seed selection: Pick fully mature camellia oleifera fruits within 15 days after the frost, store the camellia oleifera fruits until the peel cracks, take out the seeds, and screen out the seeds that are large, plump and free from diseases and insect pests.

[0033] 2. Drying: After the screened Camellia oleifera seeds are aired for 15 days, they are dried in a low-temperature and low-humidity drier at a temperature of 5-10°C and a relative humidity of 20-25% to a water content of 10%.

[0034] 3. Packaging: Put the seeds into a PA+PE vacuum bag with a thickness of 16 wires, and vacuum seal it.

[0035] 4. Storage: Store the camellia oleifera seeds in sealed vacuum bags in a cold storage with a temperature of 0-4°C and a relative humidity of 60%.

[0036] The germination rate of Camellia oleifera seeds stored for 3 years was 91.6%.

Abstract

The invention belongs to the technical field of plant seed storage, and more specifically relates to a camellia oleifera seed vacuum package refrigeration method. The camellia oleifera seed vacuum package refrigeration method comprises following steps: 1, large plump camellia oleifera seeds without diseases or insects harvested in 15 days after First Frost are adopted; 2, the selected camellia oleifera seeds are subjected to airing for 15 days, and are dried at a low temperature and a low humidity; 3, the camellia oleifera seeds are packaged with vacuum bags, and vacuum-pumping sealing is carried out; and 4, the camellia oleifera seeds sealed in the vacuum bags are stored in a refrigeration house. According to the method, the deterioration speed of camellia oleifera seeds is reduced at lowpressure low oxygen low temperature conditions, seed germination rate after storage is increased, and it is beneficial for long term storage of camellia oleifera seeds.

Description

technical field [0001] The invention relates to the technical field of plant seed storage, in particular to a vacuum-packed and refrigerated method for camellia oleifera seeds. Background technique [0002] Camellia oleifera (Camellia oleifera Abel) is an economic forest species with high production value in the family Theaceae, and it is the main woody oil tree species in my country. Planting Camellia oleifera using the natural conditions in mountainous areas is an important means of increasing farmers' economic income. It is also important to store water, conserve soil, and adjust ecological balance. Using Camellia oleifera buds as rootstocks to graft other plants of the Theaceae Camellia genus is widely used in production because of its simple operation, high survival rate and rapid growth after grafting. The grafting of Camellia oleifera sprouts as rootstock can be carried out all year round, but the Camellia oleifera seeds used to cultivate Camellia oleifera sprouts sto...
