Problems solved by technology

[0004] At present, Polygonatum is propagated by rhizomes or seeds, but the water content of rhizomes is very high, and it takes a long time from implantation in the soil to emergence, and is perishable.
However, Polygonatum seeds generally need to be germinated in the third year, and need to be refrigerated, and the emergence rate is also low.

Embodiment 1

[0031] Select the fresh rhizomes of Polygonatum rhizomes excavated from October to December every year, remove the soil and spread them in the air for 3 days, and wash the discarded rhizomes with 6-10% carbendazim solution after removing the root hairs of the rhizomes of Polygonatum. Each Polygonatum rhizome is cut into 100kg of small section rhizomes of 2 to 4 stem nodes, and after mixing with 10kg of 3 mesh granular activated carbon after sterilization, the relative humidity is maintained at about 50%, and is processed at 18°C ​​for 15 days. The small rhizomes of each sealwort were placed in a relative humidity of 65%, and subjected to low-temperature treatment at 6° C. for 40 minutes. Put the treated small section of rhizome into 6-BA containing 70mg / L, 0.04g / L GA 3 1. Soak in 30g / L carbendazim aqueous solution for 30min, take it out and put it in sterilized sand, maintain the relative humidity at 65%, light intensity 700LX, light 10h every day, temperature at 18°C, and spr...

Abstract

The invention relates to a polygonatum rhizome high-quality seedling quick cultivation method. The polygonatum rhizome high-quality seedling quick cultivation method comprises the steps of pretreatment on polygonatum rhizome, treatment of waste polygonatum rhizome, germination treatment, heat shock treatment, rooting treatment, plantlet transplantation, field management and the like. Through directly air-drying treatment on the dug polygonatum rhizome, the polygonatum rhizome high-quality seedling quick cultivation method reduces the water content in the polygonatum rhizome, retards spoilage of the polygonatum rhizome and provides conditions for subsequent rapid germination, thereby reducing consumption of high-quality polygonatum rhizome, promoting uniformity of polygonatum seedlings and greatly reducing the polygonatum planting management cost.

Description

technical field [0001] The invention specifically relates to a method for quickly cultivating high-quality seedlings from rhizomes of Rhizoma Polygonatum, and belongs to the technical field of medicinal plant cultivation. Background technique [0002] Polygonatum is also known as: Chicken Head Polygonatum, Yellow Chicken Vegetable, Pen Tube Vegetable, Claw Ginseng, Tiger Ginger, Chicken Claw Ginseng. The rhizome is cylindrical, and due to the swelling of the nodules, the "internode" is thick at one end and thin at the other end, and there are short branches at the thick end (Chinese medicine records say that the medicinal material made from this type of rhizome is Chicken Head Polygonatum) , 1 to 2 cm in diameter. Stem height 50-90 cm, or up to 1 m, sometimes climbing. The leaves are whorled, 4 to 6 in each round, strip-lanceolate, 8 to 15 cm long, 6 to 16 mm wide (4 to 16 mm), and the apex is curled or bent into a hook. The inflorescence usually has 2-4 flowers, which se...
