Problems solved by technology

[0006] Aiming at the problems that Polygonatum rhizome itself has high water content and sufficient starch content, the germination rate is not high by directly adopting cut rhizomes to cultivate in sections, and the cultivated sprouts are not strong, and premature aging is prone to occur under strong light, etc., the invention provides a Polygonatum seedling and Polygonum cuspidatum The method of nesting, the sprouts cultivated by this method have the characteristics of robustness, no disease, high germination rate, etc., which are suitable for industrial production, the formula effect is good, the germination rate is high, the buds are strong, the plant growth period is long, and the operability is strong. Advanced merit

Embodiment 1

[0036] Choose the fresh rhizomes of Polygonatum that are excavated from October to December every year, remove the soil and lay them and expose them to wind for 3 days, remove the roots of Polygonatum rhizomes and wash the discarded rhizomes with 6-10% carbendazim solution. Cut each rhizome of Polygonatum into 2-4 small segments of rhizome 100kg, and then mix with 10kg of 3 mesh granular activated carbon after sterilization, the relative humidity is maintained at about 50%, and the treatment is performed at 18°C ​​for 15 days. The rhizomes of each rhizome of Polygonatum are placed at a relative humidity of 65% and subjected to a low temperature treatment at 6°C for 40 minutes. Put the treated rhizomes into 6-BA containing 70mg / L, 0.04g / L GA 3 , 30g / L carbendazim aqueous solution for 30min, take out and put it in sterilized sand, maintain relative humidity at 65%, light intensity 700LX, light for 10h a day, temperature at 18℃, and shoot buds in 30 days. Put the rhizomes of Polyg...

Embodiment 2

[0040] Choose the fresh rhizomes of Polygonatum that are excavated from October to December every year, remove the soil and lay them and expose them to wind for 3 days, remove the roots of Polygonatum rhizomes and wash the discarded rhizomes with 6-10% carbendazim solution. Cut each rhizome of Polygonatum into 2-4 small segments of rhizome 100kg, and then mix with 25kg of sterilized 5-mesh granular activated carbon. The relative humidity is maintained at 55% and treated at 20°C for 25 days. The rhizomes of each rhizome of Polygonatum are placed at a relative humidity of 65% and subjected to low temperature treatment at 3°C ​​for 60 minutes. Put the treated rhizomes into 6-BA containing 90mg / L, 0.05g / L GA 3 , 50g / L carbendazim aqueous solution soaked for 30min, take it out and put it in sterilized sand, maintain relative humidity at 70%, light intensity 600LX, light for 12h every day, temperature at 15℃, and shoot buds in 35 days. Put the rhizomes of Polygonatum sylvestris at 50...

Abstract

The invention relates to a method of rhizoma polygonati seedling rearing and intercropping with polygonum cuspidatum. The method comprises the steps of pretreatment of rhizoma polygonati root, treatment of polygonatum odoratum discarded root, activation treatment, bud inducing treatment, heat exciting treatment, root inducing treatment, seedling transplanting, polygonum cuspidatum cultivation, rhizoma polygonati large field management, ensuing year rhizoma polygonati, polygonum cuspidatum growth period management, and rhizoma polygonati and polygonum cuspidatum harvesting. The method can reduce the use amount of high quality rhizoma polygonati, promotes the neat consistency of the rhizoma polygonati seedlings, and greatly reduces the management cost of rhizoma polygonati culture. The rhizoma polygonati seedlings obtained through the method are artificially cultivated, the seedling rate is higher than the breeding rate of directly buried rhizome, together with polygonum cuspidatum, rhizoma polygonati can adapt to the natural environment more quickly, the planting years of rhizoma polygonati can be shortened, and the content of the polysaccharide of polygonatum is improved.

Description

Technical field [0001] The invention belongs to the technical field of cultivation of medicinal plants, and specifically relates to a method for raising Polygonatum rhizome seedlings and efficiently nesting Polygonum cuspidatum. Background technique [0002] Polygonatum is also called chicken head polygonatum, yellow chicken dish, pen tube dish, claw ginseng, tiger ginger, chicken claw ginseng. The rhizome has a cylindrical shape. Because the nodules are enlarged, the "internodes" are thick at one end and thin at the other end, with short branches at the thick end (Chinese medicine records that the medicinal material made from this rhizome type is called Polygonatum) , 1-2 cm in diameter. The stems are 50 to 90 cm high, or up to 1 meter or more, sometimes in a climbing shape. Impellers are born, 4-6 per round, strip-lanceolate, 8-15 cm long, 6-16 mm wide (4~), and the tip is rolled or bent into a hook. The inflorescence usually has 2 to 4 flowers, resembling an umbrella shape,...
