Embodiment 1

[0015] A kind of storage method of Magnolia magnolia seed, comprises the following steps:

[0016] (1) Picking and drying: Pick the fruit with cracks, take out the seeds, and dry them at 42°C until the water content is 6%, which is beneficial to speed up the absorption of the treatment solution during post-processing, and dry seeds are obtained;

[0017] (2) Freeze soaking: soak the dried seeds in an alcohol solution with a volume fraction of 66%, and freeze them at -24°C for 7 hours without freezing. Low temperature stimulates the stress resistance of the germ, maintains the activity of the germ, and prolongs the storage period. Take out, filter, wash with water, and get frozen seeds;

[0018] (3) Ultrasonic seed dressing: Soak the frozen seeds in the seed dressing solution with a mass fraction of 3.3%, and ultrasonicate at 32kHz for 40 minutes to promote the soaking of the seed dressing solution in the seeds, provide nutrition, antibacterial and insecticidal, and prolong the...

Embodiment 2

[0023] A kind of storage method of Magnolia magnolia seed, comprises the following steps:

[0024] (1) Picking and drying: Pick the fruit with cracks, take out the seeds, and dry them at 43°C until the water content is 7%, which is beneficial to speed up the absorption of the treatment solution during post-processing, and dry seeds are obtained;

[0025] (2) Freezing soaking: Soak the dried seeds in an alcohol solution with a volume fraction of 67%, and freeze them at -23°C for 8 hours without freezing. The low temperature stimulates the stress resistance of the germ, maintains the activity of the germ, and prolongs the storage period. Take out, filter, wash with water, and get frozen seeds;

[0026] (3) Ultrasonic seed dressing: Soak the frozen seeds in a seed dressing solution with a mass fraction of 3.4%, and ultrasonicate at 33kHz for 43 minutes to promote the soaking of the seed dressing solution in the seeds, provide nutrition, antibacterial and insecticide, and prolong ...

Embodiment 3

[0031] A kind of storage method of Magnolia magnolia seed, comprises the following steps:

[0032] (1) Picking and drying: Pick the fruit with cracks, take out the seeds, and dry them at 44°C until the water content is 8%, which will help to speed up the absorption of the treatment solution during post-processing, and dry the seeds;

[0033] (2) Freeze soaking: Soak the dried seeds in an alcohol solution with a volume fraction of 68%, and freeze them at -22°C for 9 hours without freezing. The low temperature stimulates the stress resistance of the germ, maintains the activity of the germ, and prolongs the storage period. Take out, filter, wash with water, and get frozen seeds;

[0034] (3) Ultrasonic seed dressing: Soak the frozen seeds in the seed dressing solution with a mass fraction of 3.5%, and ultrasonicate at 34kHz for 45 minutes to promote the soaking of the seed dressing solution in the seeds, provide nutrition, antibacterial and insecticidal, and prolong the storage ...

Abstract

The invention mainly relates to the field of planting, and discloses a storage method of magnolia grandiflora seeds. The method comprises the steps: picking, drying, freezing, immersing, ultrasonically stirring the seeds, drying, and storing. The method is simple and easy in operation, the magnolia grandiflora seeds can be stored for 3 years, the germination rate of the seeds after being stored for 3 years is 73 percent, the germination time is 12 to 13 days, the seeds are saved, and the economic income can be increased by 12.6 percent; the seeds are dried after being picked, so that the moisture content is reduced, and the absorption of a treatment solution in later treatment can be accelerated; low-temperature freezing is carried out after an alcohol solution is added, so that icing is prevented, the stress resistance of germs is stimulated at low temperature, the activity of the germs is kept, and the storage period is prolonged; a seed-dressing agent is a pure plant extraction agent and is safe and non-toxic to a human body and the environment, the seeds are ultrasonically stirred in the seed-dressing agent, the immersion of the seed-dressing agent on the seeds is facilitated, nutrition is provided, an antibacterial and insecticidal effect is achieved, and the storage period is prolonged; after the seeds are baked and dried, the activity of the germs in the seeds is kept, the high-temperature stress resistance of the germs is stimulated, and the storage period is prolonged.

Description

technical field [0001] The invention mainly relates to the field of planting technology, in particular to a method for storing Magnolia magnanimum seeds. Background technique [0002] Magnolia magnolia, alias: Magnolia magnolia, has a majestic tree posture, broad leaves and thick shade, flowers like lotus, and fragrant fragrance. It is a beautifying tree species, resistant to smoke and wind, and has strong resistance to toxic gases such as sulfur dioxide. It can be used to purify the air. It protects the environment and has high ornamental value; and the buds of Magnolia Magnolia can lower blood pressure, antibacterial and anti-inflammatory, and treat vomiting, diarrhea and migraine. [0003] The seeds of Magnolia magnolia are picked and stored in sand, and then directly sown. The germination rate can only reach about 75%, and the germination time is long. It takes 30-40 days to germinate after sowing, resulting in extremely low planting efficiency, and the germination rate ...
