Problems solved by technology

In recent years, as the medicinal value and health value of Polygonatum are more and more recognized by people, the demand for raw materials of Polygonatum is also increasing, and the price continues to rise, which leads to the intensification of predatory collection of wild Polygonatum by farmers in mountainous areas. The natural resources of Rhizoma Polygonatum are rapidly exhausted, which brings adverse effects on the development, utilization and sustainable development of Rhizoma Polygonatum plants
At present, rhizome vegetative propagation is mostly used in the artificial cultivation of Polygonatum, which is a waste of resources and is not conducive to large-scale production and promotion. Long-term vegetative propagation not only causes germplasm degradation, but also becomes more and more serious, especially soil-borne diseases become more serious with the increase of reproduction generations
[0003] The application of seed propagation is an effective way to solve soil-borne diseases and reduce production costs. However, Polygonatum multiflora seeds have dormancy characteristics. The natural germination of Polygonatum seeds requires two winter dormancy before they can grow a true leaf. From sowing to harvesting As long as 5 to 6 years, and now the method of winter sand layering is generally used, but there are still shortcomings such as low germination rate and irregular emergence, so the problem of Polygonatum seedlings has become a bottleneck for artificial large-scale planting

Embodiment 1

[0024] 1. Seed collection and storage: Collect mature Polygonatum multiflora fruits in September, and select seeds with strong mother plants, no pests and diseases, and full fruits for harvesting. The standard for harvesting Polygonatum multiflora seeds is: when the berries turn from green to yellow or black and mature. The harvested Polygonatum multiflora fruit is placed in a light-tight sealed plastic bag, and fermented at 25°C for 10 days. It is advisable that the exocarp is rotten, soft and easy to fall off. Put the fermented fruit on a 12-mesh sieve and knead repeatedly, or add about 1 / 3 of the volume of fine sand to knead until the peel and pulp are completely removed, rinse with clean water, remove the fine sand and impurities, filter the water and set aside Store in refrigerator at 4°C.

[0025] 2. Seed germination: Take out the seeds in February of the next year, place them in an ultrasonic instrument (frequency 20kHz), add gibberellin (60mg / L), and adjust the pH val...

Embodiment 2

[0028] 1. Seed collection and storage: Collect mature Polygonatum multiflora fruits in October, and select seeds with strong mother plants, no pests and diseases, and full fruits for harvesting. The standard for harvesting Polygonatum multiflora seeds is: harvest when the berries turn from green to yellow or black and mature. Put the harvested Polygonatum fruit in a light-tight sealed plastic bag, and ferment for 10 days at 18°C. The exocarp is rotten and soft and easy to fall off. Put the fermented fruit on a 12-mesh sieve, add about 1 / 3 of the volume of fine sand, and knead repeatedly until the peel and pulp are completely removed, rinse with clean water, remove the fine sand and impurities, filter the water and put it in a 4°C refrigerator storage.

[0029] 2. Seed germination: Take out the seeds in February of the next year, place them in an ultrasonic instrument (frequency 30kHz), add gibberellin (50mg / L), and adjust the pH value between 6 and 6.5 with 1mol / L hydrochlori...

Embodiment 3

[0032] 1. Seed collection and storage: In October, select seeds with strong mother plants, no pests and diseases, and full fruits for harvesting. The standard for harvesting Polygonatum multiflora seeds is: harvest when the berries turn from green to yellow or black and mature. The harvested Polygonatum multiflora fruit is placed in a light-tight sealed plastic bag, and fermented at 18-25°C for 7-10 days. It is advisable that the exocarp is rotten and soft and easy to fall off. Put the fermented fruit on a 12-mesh sieve and knead it repeatedly until the peel and pulp are completely removed, rinse with clean water to remove fine sand and impurities, filter the water and store in a refrigerator at 4°C.

[0033] 2. Seed germination: Take out the seeds in March of the following year, place them in an ultrasonic instrument (frequency 40kHz), add gibberellin (80mg / L), and adjust the pH value between 6 and 6.5 with 1mol / L hydrochloric acid or sodium hydroxide. Use an oxygen pump to ...

Abstract

The invention provides a germination acceleration and seedling cultivation method for a polygonatum cyrtonema seed and relates to the technical field of polygonatum sibiricum red cultivation. The ultrasound, gibberellins, high dissolved oxygen and weak acid environment are utilized to promote dormancy release of the polygonatum cyrtonema seed, thus the polygonatum cyrtonema seeds can emerge neatlywithin six months, emergence rate can reach 90% or above, entire period of seedling cultivation is effectively reduced, the germination rate and the seedling rate of the polygonatum cyrtonema seed are increased.

Description

technical field [0001] The invention belongs to the technical field of Polygonatum multiflora cultivation, and in particular relates to a method for accelerating germination of Polygonatum multiflora seeds and cultivating seedlings. Background technique [0002] Polygonatum sibiricum Red., Polygonatum cyrtonema Hua. and Polygonatum kingianum Coll. et Hemsl. are perennial herbaceous plants of the Liliaceae. The base plant of Rhizoma Polygonatum is a perennial herb with the same origin of medicine and food, and it is a traditional bulk medicinal material in my country. The rhizome of Polygonatum is a traditional Chinese medicine. Modern pharmacological studies have shown that Polygonatum saponins, sugars, quinones, amino acids and trace elements have the functions of stimulating immunity, enhancing immunity, delaying aging, and antiviral effects. In recent years, as the medicinal value and health value of Polygonatum are more and more recognized by people, the demand for raw m...
