Embodiment 1

[0014] Embodiment 1: carry out according to the following steps:

[0015] Step 1: After the Polygonatum multiflora fruit matures and turns black, harvest and scrub to obtain clean seeds, mix the seeds with wet sand so that the seeds are not connected together, store at low temperature for 110 days, take out the seeds and wash them.

[0016] Step 2: The seeds stored in low-temperature sand and cleaned are soaked in 200ppm gibberellin for 36 hours, soaked in carbendazim for 30 minutes, washed with water, and sown in seedling trays with loose, fertile and moist substrates. After soaking in gibberellin, the germination rate of seeds can reach more than 95%.

[0017] Step 3: 4 months after sowing, the primary rhizomes of Polygonatum polyflora are fully grown, and the primary rhizomes are taken out and soaked in 300ppm of 6-BA for 24 hours.

[0018] Step 4: The primary rhizomes treated with 6-BA are transplanted in the seedling field, covered with mixed farmyard manure and finely c...

Embodiment 2

[0020] Embodiment 2: carry out according to the following steps:

[0021] Step 1: After the Polygonatum multiflora fruit matures and turns black, harvest and scrub to obtain clean seeds, mix the seeds with wet sand so that the seeds are not connected together, store at low temperature for 120 days, take out the seeds and wash them.

[0022] Step 2: The seeds stored in low-temperature sand and cleaned are soaked in 250ppm gibberellin for 32 hours, soaked in carbendazim for 40 minutes, washed with water, and sown in seedling trays with loose, fertile and moist substrates. After soaking in gibberellin, the germination rate of seeds can reach more than 95%.

[0023] Step 3: 4 months after sowing, the primary rhizomes of Polygonatum polyflora are fully grown, and the primary rhizomes are taken out and soaked in 320ppm of 6-BA for 20 hours.

[0024] Step 4: The primary rhizomes treated with 6-BA are transplanted in the seedling field, covered with mixed farmyard manure and finely c...

Embodiment 3

[0026] Embodiment 3: carry out according to the following steps:

[0027] Step 1: After the Polygonatum multiflora fruit matures and turns black, harvest and scrub to obtain clean seeds, mix the seeds with wet sand so that the seeds are not connected together, store at low temperature for 150 days, take out the seeds and wash them.

[0028] Step 2: The seeds stored in low-temperature sand and cleaned were soaked in 180ppm gibberellin for 40 hours, soaked in carbendazim for 30 minutes, washed with water, and sowed in seedling trays equipped with loose, fertile and moist substrates. After soaking in gibberellin, the germination rate of seeds can reach more than 95%.

[0029] Step 3: 4 months after sowing, the primary rhizomes of Polygonatum polyflora are fully grown, and the primary rhizomes are taken out and soaked in 200ppm of 6-BA for 28 hours.

[0030] Step 4: The primary rhizomes treated with 6-BA are transplanted in the seedling field, covered with mixed farmyard manure a...

Abstract

The invention discloses a polygonatum cyrtonema seed rapid emerging method. Polygonatum cyrtonema fruits are harvested and washed after the fruits are mature to obtain clean seeds for cold sand storage immediately, dormancy is removed from hypocotyl after storage treatment of 120 days, the seeds are treated with gibberellin with proper concentration and soaking time and are not sprouted, and emerging doesn't occur in the current year; gibberellin treated seeds are sown in a seedling plate loaded with a loose, fertile and moist substrate, primary roots of polygonatum cyrtonema are grown fully after four months, dormancy is removed from epicotyl after the primary roots are taken out and treated with cytokinin 6-BA with proper concentration and soaking time, the seeds are transplanted in a shading seedling field, emerging starts after about 15 days, the emerging is uniform, and the emergence rate can be as high as 70%. The polygonatum cyrtonema seed rapid emerging method has the advantages that the seed germination rate is high after treatment, the emergence rate is high, and the seedling culture time is reduced by one year.

Description

technical field [0001] The invention relates to the technical field of seedling breeding and breeding of medicinal plant seeds, in particular to the breeding technology of Polygonatum multiflora seeds. Background technique [0002] Polygonatum multiflora is a species of Polygonatum specified in the Pharmacopoeia, which has the effects of invigorating qi and nourishing yin, invigorating the spleen, moistening the lungs and benefiting the kidneys. In recent years, with the in-depth research on the efficacy of sealwort and the advent of sealwort health products and health medicines, the market demand for sealwort is increasing day by day. Polygonatum is a perennial plant with slow growth and a long cycle. In recent years, a large number of excavations have caused the rapid decline of wild resource reserves and the destruction of the environment. The artificial cultivation technology of Polygonatum can solve the contradiction between supply and demand and protect the ecological...
