Embodiment 1

[0011] A method for pre-germination pre-germination of pecan seeds in winter, comprising the following content: select healthy and plump seeds of pecans with thin shells, dry them until the moisture content is lower than 20%, and then keep them warm for 2.5 hours at a temperature of 4°C , and then put it into the treatment solution with a temperature of 38°C, stir and soak for 18 minutes, drain the water and accelerate germination; the treatment solution contains the following raw materials in weight percentage: 4% lactose, 1.2% L-phenylalanine, 0.6% polyvinylpyrrolidone, 0.2% phenoxyethanol, and the balance is water.

[0012] Wherein, the drying method is to dry under natural conditions or air-flow drying at a temperature of 60°C; when the treatment solution soaks the seeds, the amount of the treatment solution is 8 cm below the seeds; when the treatment solution soaks the seeds The stirring speed is 100 rpm; the seed surface humidity is lower than 30% during the germination;...

Embodiment 2

[0014] A method for pre-germination pre-germination of pecan seeds in winter, comprising the following content: select healthy and plump seeds of pecans with thin shells, dry them until the water content is lower than 20%, and then keep them warm for 3 hours at a temperature of 2°C , and then put it into the treatment solution with a temperature of 35°C, stir and soak for 15 minutes, drain the water and accelerate germination; the treatment solution contains the following raw materials in weight percentage: lactose 4.2%, L-phenylalanine 0.6%, 0.4% polyvinylpyrrolidone, 0.1% phenoxyethanol, and the balance is water.

[0015] Wherein, the drying method is to dry under natural conditions or air-flow drying at a temperature of 65°C; when the seeds are soaked in the treatment solution, the amount of the treatment solution is 10 cm below the seeds; when the seeds are soaked in the treatment solution, The stirring speed is 120 rpm; the seed surface humidity is lower than 30% during t...

Embodiment 3

[0017] A pre-germination treatment method for pecan seeds in winter, comprising the following content: select healthy and plump seeds of pecans with thin shells, dry them until the water content is lower than 20%, and then keep them warm for 2 hours at a temperature of 5°C , and then placed in a treatment solution with a temperature of 40°C, stirred and soaked for 20 minutes, drained and accelerated germination; the treatment solution contains the following raw materials in weight percentages: 3.8% lactose, 1.5% L-phenylalanine, 0.8% polyvinylpyrrolidone, 0.3% phenoxyethanol, and the balance is water.

[0018] Wherein, the drying method is to dry under natural conditions or air-flow drying at a temperature of 55°C; when the treatment solution soaks the seeds, the amount of the treatment solution is 6 cm below the seeds; when the treatment solution soaks the seeds The stirring speed is 80 rpm; the seed surface humidity is lower than 30% during the germination; the germination s...

Abstract

The invention belongs to the technical field of carya illinoensis seed pregermination, and particularly relates to a carya illinoensis seed winter pregermination pretreatment method. The method comprises the following steps of picking healthy and full carya illinoensis seeds; drying the seeds until the water content is lower than 20 percent; performing heat insulation for 2 to 3 hours under the temperature condition of 2 to 5 DEG C next, putting the seeds into a treatment solution with the temperature being 35 to 40 DEG C; performing stirring soaking for 15 to 20 minutes; draining moisture; then, performing pregermination. Compared with the prior art, the method provided by the invention has the following advantages that the pregermination treatment method is used for performing physiological training on the seeds, so that the germinating effects at the low temperature is good; the low-temperature-resistant capability of young seedlings is effectively improved; the operation method issimple; the conditions can be easily controlled; the low production cost is ensured; meanwhile, the emergence rate of the seeds is effectively improved; the seedling regular rate is high; the method is suitable for being popularized and used.

Description

technical field [0001] The invention belongs to the technical field of germination-promoting pecans, and in particular relates to a pre-germination method for pecan seeds in winter. Background technique [0002] Thin-shelled pecans are one of the famous dried fruits in the world. They are rich in protein, plant sterols, especially unsaturated fatty acids. Studies have shown that the edible part of thin-shelled pecans has a moisture content of 2.1%-6.4% and a protein content of 6.0%. -11.3%, lipid content 65.9-78.0%, total soluble sugar is 3.3-5.3%, hickory nuts contain monounsaturated fatty acids and polyunsaturated fatty acids, which can reduce the linoleic acid absorbed by cancer from the blood Quantity, there is obvious anti-cancer effect, is more and more subject to liking of the public as a kind of nutraceutical food, and China carries out research work from many aspects such as real resource investigation, introduction, variety selection, seedling raising, high-yield c...
