Embodiment 1

[0025] A method for promoting the germination of Nanjing Tilia seeds by magnetic treatment, the specific steps comprising:

[0026] 1. Shelling the seeds

[0027] Use iron tongs to crush the fruit shell, and take out the seeds. Be careful not to break the seed coat. Some obviously empty or damaged seeds should be removed in time.

[0028] 2. Select full seeds by water

[0029] Put the shelled seeds into a washbasin or a large container, and stir them thoroughly with a glass rod; after 30 minutes, remove the seeds floating on the water surface, and take out the seeds that sink to the bottom and drain the water. These seeds are full seeds; put the full seeds in Put it on 3-5 layers of newspaper or absorbent paper, and use the paper to absorb the moisture on the surface of the seeds.

[0030] 3. Etching seeds with concentrated sulfuric acid

[0031] Put 100-150g of seeds in a 1000ml beaker, add 250-300ml of concentrated sulfuric acid; the acid etching time of concentrated sulf...

Abstract

The invention provides a method for promoting germination of tilia miqueliana seeds by magnetic treatment. Conditions such as the concentrated sulfuric acid etching time of the tilia miqueliana seeds, the seed soaking time of a gibberellin solution and the magnetized water treatment intensity and the frequency in a low-temperature lamination process are strictly controlled; the method is implemented by seed hulling, acid etching by concentrated sulfuric acid, seed soaking by the gibberellin solution, magnetized water treatment, low-temperature lamination and germination environment control; the control on key steps in the dormancy relieving and germination processes of the tilia miqueliana seeds is enhanced, and a magnetic biological effect is applied to the dormancy relieving and germination processes of the seeds, so that the dormancy of the seeds can be quickly relieved, and the seeds are germinated; the effects of high germination speed, tidy germination, high seedling rate and the like are achieved; the technical difficulty in multiplication of the tilia miqueliana seeds is solved; the germination rate of full seeds is over 90 percent, and the seedling rate is over 85 percent; a better sprout foundation is laid for realizing the industrial development of tilia miqueliana seedling cultivation.

Description

technical field [0001] The invention relates to the field of tree seedling propagation, in particular to a method for promoting the germination of Nanjing linden seeds by magnetic treatment. Background technique [0002] Nanjing Tilia (Tilia miqueliana Maxim.), also known as Tilia miqueliana Maxim., is commonly known as "linden tree". Nanjing linden has a strong fragrance, thick leaves, and tall and straight trunks. It is a landscaping, medicinal, timber, and nectar plant. Because of its mysterious religious and cultural color, it has been introduced and cultivated in Japan in large numbers. Nanjing Tilia was once widely distributed as a native tree species in East China, but due to difficult reproduction and habitat destruction, its population and individual numbers have gradually declined. Research on reproductive technology has become a top priority for the protection, development and utilization of Nanjing Tilia resources! [0003] The propagation technology of Nanjing ...
