Embodiment 1

[0019] A kind of quick germination method of ginkgo seed, comprises the following steps:

[0020] (1) Fermentation: After the ginkgo fruit is picked, keep the outer testa. After the fruit is piled up, add agarose pulp with 16% fruit weight, mix evenly, add mixed bacteria, mix evenly, and ferment at 36°C for 20 hours. Seed proliferation, lower the temperature to 21°C, stir evenly, continue to ferment for 4 days, make full use of the nutrients in the seed coat, produce more small molecule nutrients and fermentation products, then cool down to 2°C, stand for 2 days, stir evenly, and promote The fermentation product enters the seed shell, enhances the water retention capacity of the seed, inhibits the activity of dormant substances, breaks the dormancy of the seed, accumulates more nutrients, promotes seed germination, filters, and obtains fermented seeds and fermented pulp;

[0021] (2) Drying: Freeze-dry the fermented seeds, the freezing temperature is -44°C, the shelf heating t...

Embodiment 2

[0031] A kind of quick germination method of ginkgo seed, comprises the following steps:

[0032] (1) Fermentation: After the ginkgo fruit is picked, the outer testa is kept, and after the fruit is piled up, add agarose pulp with 17% fruit weight, mix well, add mixed bacteria, mix well, and ferment at 37°C for 21 hours, promote bacteria Seed proliferation, lower the temperature to 22°C, stir evenly, continue to ferment for 4 days, make full use of the nutrients in the seed coat, produce more small molecule nutrients and fermentation products, then cool down to 3°C, stand for 2 days, stir evenly, and promote The fermentation product enters the seed shell, enhances the water retention capacity of the seed, inhibits the activity of dormant substances, breaks the dormancy of the seed, accumulates more nutrients, promotes seed germination, filters, and obtains fermented seeds and fermented pulp;

[0033] (2) Drying: Freeze-dry the fermented seeds, the freezing temperature is -43°C,...

Embodiment 3

[0043] A kind of quick germination method of ginkgo seed, comprises the following steps:

[0044] (1) Fermentation: After the ginkgo fruit is picked, keep the outer testa, after piling up the fruit, add agarose pulp with 18% fruit weight, mix evenly, add mixed bacteria, mix evenly, and ferment at 38°C for 22 hours, promote bacteria Seed proliferation, lower the temperature to 23°C, stir evenly, continue to ferment for 5 days, make full use of the nutrients in the seed coat, produce more small molecule nutrients and fermentation products, then cool down to 4°C, let stand for 3 days, stir evenly, and promote The fermentation product enters the seed shell, enhances the water retention capacity of the seed, inhibits the activity of dormant substances, breaks the dormancy of the seed, accumulates more nutrients, promotes seed germination, filters, and obtains fermented seeds and fermented pulp;

[0045] (2) Drying: Freeze-dry the fermented seeds, the freezing temperature is -42°C, ...

Abstract

The invention mainly relates to the field of planting technologies and discloses a quick germination accelerating method for seeds of gingko. The method includes the steps of: fermentation, drying, seed dressing, and germination acceleration. The method is easy and convenient to operate, wherein initial germinating time is reduced to 7.42 days, and germination rate reaches 82.3%; the method significantly increases planting efficiency and increases economic income by 23.7%. When gingko fruits are picked, the gingko fruits are fermented with addition of gelidium amansii slurry, wherein proliferation of a bacterial strain is promoted at high temperature and then the fermentation is carried out at low temperature, so that the nutrients in seed coats are fully utilized to produce a large amount of small-molecular nutrients and fermented products; after fermentation, the seeds stand at low temperature so that the fermented products enter seed shells, thereby enhancing water retention capability of the seeds, inhibiting activity of dormancy substances, breaking seed dormancy, accumulating more nutritional components, and accelerating the germination of the seeds.

Description

technical field [0001] The invention mainly relates to the technical field of planting, in particular to a method for rapid germination of ginkgo seeds. Background technique [0002] Ginkgo biloba is commonly known as ginkgo, so ginkgo tree is also known as ginkgo tree. It is the oldest relict plant among the gymnosperms left over from the Quaternary glacier movement, so ginkgo is also known as a living fossil. Ginkgo biloba not only has high ecological value, but also has strong adaptability, anti-smoke, anti-fire, anti-toxic gas, tall tree, straight trunk, beautiful posture, green in spring and summer, and golden in late autumn. It is one of the four long-lived ornamental tree species (pine, cypress, locust tree, ginkgo) in China. It also has high medicinal value. Cerebrovascular, beauty and skin care, anti-aging. [0003] One of the main propagation methods of ginkgo trees is sowing propagation, which is simple and easy to operate. At present, ginkgo trees need to be ac...
