Embodiment 1

[0029]A method of breaking the seeds of gold cherry seeds and increasing germination rates, as follows:

[0030]A, seed pretreatment

[0031]Choose the fruit peel hosted from Mid October 2020, 2020, ripe, rushing into the fruit skin, peel off the outer fruit skin, then remove the impurities and null seeds, get full of strong gold cherry The seed is 400 capsules (100 grains is a repetition, a total of 4 repetitions), and then washed 5 times with water, and dry off at room temperature.

[0032]B, soaked

[0033]The gold seed seed treated by step A was soaked in a 5 μmol / l Karrikinolide aqueous solution for 24 hours, and each 100 seeds were soaked with a 50 ml karrikinolide anhydrous solution, and 4 repeating groups were soaked separately. After the soaking, the seed was baked.

[0034]C, low temperature lamination

[0035]The seeds of each repeated group treated by step B are mixed with the proportion of weight ratio 1: 5 (100 gold sakiviled seeds is about 1 g), placed in a sealed plastic bag, seeds ...

Embodiment 2

[0042]A method of breaking the seeds of gold cherry seeds and increasing germination rates, as follows:

[0043]A, seed pretreatment

[0044]Choose the fruit peel hosted from Mid October 2020, 2020, ripe, rushing into the fruit skin, peel off the outer fruit skin, then remove the impurities and null seeds, get full of strong gold cherry The seed is 400 capsules (100 grains is a repetition, a total of 4 repetitions), and then washed 3 times with water, and dry off at room temperature.

[0045]B, soaked

[0046]The gold cherry seed treated by step A was soaked in an aqueous solution of 8 μmol / l Karrikinolide aqueous solution for 24 hours, and each 100 seeds were soaked with a 50 ml karrikinolide aqueous solution, and 4 repeating groups were soaked separately. After the soaking, the seed was baked.

[0047]C, low temperature lamination

[0048]The seeds of each repeating group treated by step B are mixed uniform with the proportion of weight ratio 1: 5, placed in a sealing plastic bag, seeds and pearl...

Embodiment 3

[0055]A method of breaking the seeds of gold cherry seeds and increasing germination rates, as follows:

[0056]A, seed pretreatment

[0057]Choose the fruit peel hosted from Mid October 2020, 2020, ripe, rushing into the fruit skin, peel off the outer fruit skin, then remove the impurities and null seeds, get full of strong gold cherry The seed is 400 capsules (100 grains is a repetition, a total of 4 repetitions), and then washed 5 times with water, and dry off at room temperature.

[0058]B, soaked

[0059]The gold cherry seed treated by step A was soaked in a 10 μmol / l karrikinolide aqueous solution for 24 hours, and each 100 seeds were soaked with a 50 ml karrikinolide aqueous solution, and 4 repeating groups were soaked separately. After the soaking, the seed was baked.

[0060]C, low temperature lamination

[0061]The seeds of each repeating group treated by step B are mixed uniform with the proportion of weight ratio 1: 5, placed in a sealing plastic bag, seeds and pearl rock mixtures, 1 / 3 ...

Abstract

The invention discloses a method for breaking dormancy of rosa laevigata michx seeds and increasing germination rate. The method comprises the following steps that (1), seeds are soaked in a Karrikinolide aqueous solution with the concentration of 5-10 [mu]mol / L for 24 hours; (2), the soaked seeds are mixed with perlite, and low-temperature stratification is carried out at 4 DEG C for 30-40 days; (3), the laminated seeds are soaked in an aqueous solution containing 5-15 [mu]mol / L of sodium nitroprusside and 2.5-10 mmol / L of hydrogen peroxide for 24 hours; and (4), sowing is carried out in a sand bed. According to the method for breaking the dormancy of the rosa laevigata michx seeds and increasing germination rate, the dormancy of the rosa laevigata michx seeds is broken and the germination rate of the rosa laevigata michx seeds is increased in a 'seed soaking, lamination and seed soaking' mode, so that the germination rate of the rosa laevigata michx seeds reaches 80% or above, the lamination time in a traditional rosa laevigata michx seed dormancy breaking method is greatly shortened, and the technical bottleneck problem of large-scale production of rosa laevigata seedling plants is solved.

Description

Technical field[0001]The present invention belongs to the cultivation of Chinese herbal medicines, and in particular, the present invention relates to a method of breaking the seeding and improving germination rate of gold cotrane seeds.Background technique[0002]The dried mature fruit of Rosacea Michx is a dry mature fruit of the rosica. It belongs to the traditional medicinal materials in the field of Chinese medicine. It has the function of kidney and insulation and diarrhea. Indicates hypertension, neurasthenia, long cough, night sweat , Spleen deficiency, diarrhea, rheumatoid arthritis and other conditions. Modern Pharmacological Studies have found that Jinchenzi has hematopoietic, blood circulation, softening artery, detoxification antibacterial, and inhibitory effects on flu viruses, and the key components in some Western medicine need to be extracted from Jinchenzi. With the increasing demand in the medical market in recent years, and the current situation of the production o...
