Problems solved by technology

However, the long-term asexual reproduction has caused the hybridization of Polygonatum plants, resulting in the degeneration of the variety provenance, poor stress resistance, and serious plant virusization, which affects the yield and product quality of planting. Polygonatum is cultivated with rhizomes, which has a large amount of seeds and low reproduction coefficient, which limits Promote planting on a large scale

Embodiment 1

[0026] The invention discloses a method for breeding Polygonatum polyflora seedlings, which comprises the following steps:

[0027] The first step, saving seeds and seed breeding: select high-quality, robust and high-yielding wild Polygonatum multiflora for cultivation and as a seed plant. The fruit balls of Polygonatum multiflora reach the initial ripening stage in mid-August, and the outer skin of the pericarp becomes dark green. When it turns black, it is in the best state of maturity. It is picked in batches, and the seeds of the green skin are not harvested. The Polygonatum multiflora fruit harvested in this example is black Ruan Guo, which is sealed in a plastic bag and fermented for 6 days before use. Manual washing and peeling to obtain clean Polygonatum multiflora seeds;

[0028] The second step, seed low-temperature sand storage treatment: put the clean seeds obtained in the first step in sterilized wet sand, the humidity of the wet sand is 30%, that is, the mass rat...

Embodiment 2

[0035] The first step, saving seeds and seed breeding: select high-quality, robust and high-yielding wild Polygonatum multiflora for cultivation and as a seed plant. The fruit balls of Polygonatum multiflora reach the initial ripening stage in mid-August, and the outer skin of the pericarp becomes dark green. When it turns black, it is in the best state of maturity. It is picked in batches, and the seeds of green skin are not harvested. The picked fruit is sealed in a plastic bag and fermented for 10 days, and then the seeds are washed and peeled manually to obtain clean Polygonatum multiflora seeds ;

[0036] The second step, seed low-temperature sand storage treatment: put the clean seeds obtained in the first step in sterilized wet sand, the humidity of the wet sand is 40%, that is, the mass ratio of sand to water is 100:40, and the wet sand Form into a ball when you hold it, and loosen it when you let go, mix the seeds and wet sand at a ratio of 1:4, store at 4°C, and take...

Embodiment 3

[0043] The first step, saving seeds and seed breeding: select high-quality, robust and high-yielding wild Polygonatum multiflora for cultivation and as a seed plant. The fruit balls of Polygonatum multiflora reach the initial ripening stage in mid-August, and the outer skin of the pericarp becomes dark green. When it turns black, it is the best state of maturity. It is picked in batches, and the seeds of the green skin are not collected. Most of the Polygonatum polyflora fruits collected in this embodiment are dark green hard fruits, and the picked fruits are sealed in plastic bags. After 12 days of fermentation and preparation, the seeds are manually washed and peeled to obtain clean Polygonatum multiflora seeds;

[0044]The second step, seed low-temperature sand storage treatment: put the clean seeds obtained in the first step in sterilized wet sand, the humidity of the wet sand is 35%, that is, the mass ratio of sand to water is 100:35, and the wet sand Form into a ball whe...

Abstract

The invention relates to a method for breeding polygonatum multiflorum seedlings, wherein the method includes the following steps: a first step, selecting wild polygonatum multiflorum, cultivating andretaining as a seed plant, and carrying out sealed fermentation, blending, seed washing and peeling of picked ripe fruit balls as seeds; a second step, putting the clean seeds obtained in the first step into sterilized wet sand, storing and taking out the seeds; a third step, carrying out soaking treatment of the polygonatum multiflorum seeds after sand storage treatment with plant hormones, andsoaking the seeds with a germination accelerating and rooting agent; a fourth step, laying the seeds obtained after being treated in the third step in a constant-temperature incubator padded with wetfilter paper, and accelerating germination to 0.6-1 cm; a fifth step, selecting suitable land or taking a temperature-controlled greenhouse for raising seedlings, preparing a moisture surface as a seedbed, and then applying farm manure or organic fertilizers on the seedbed; a sixth step, sowing the germination-accelerated seeds on the prepared seedbed by a strip sowing method, covering with pine needles or dry withered grass, lapping a shade shed above the seedbed, and keeping moist; and a seventh step, removing the withered grass to keep the seedbed moist and shaded after seedling emergence,and combining weeding with application of the farm manure or organic fertilizers to strengthen the seedlings. The seedling breeding method is simple, is low in cost, and can improve the income of growers.

Description

technical field [0001] The invention relates to the technical field of planting medicinal and edible homologous plants, in particular to a method for breeding Polygonatum polyflora seedlings. Background technique [0002] Polygonatum sibiricum Red. is a plant of the family Liliaceae, the dried rhizome of Polygonatum sibiricum Red. Its rhizome is used as medicine. It is flat in nature and sweet in taste. It is used to treat weakness of the spleen and stomach, fatigue, lack of energy, dry mouth, lack of food, dry cough due to lung deficiency, insufficient essence and blood, internal heat and thirst, etc. It is very effective for diabetes. [0003] Polygonatum multiflora in Jiangxi exhibits the unique characteristics of the southern Polygonatum, and is mainly distributed in Yichun, Ji'an and other counties and cities, among which Tonggu is more representative, and most of them are collected in the wild, and the artificial planting technology is still immature. However, due to...
