Embodiment Construction

[0018] The specific technical solutions of the present invention are described in conjunction with the examples.

[0019] (1) Select healthy perennial Polygonatum multiflora plants, cut off all annual white and yellow-white tender parts on the rhizomes, clean them, cut them into sections with a length of 2cm to 4cm, and rhizomes with a diameter of more than 4cm can be cut into sections and then lengthwise Split into two as propagating material;

[0020] (2) Potassium permanganate solution is used to disinfect the Polygonatum polyflora rhizome section obtained in step (1), and dry in the shade;

[0021] (3) Utilize the specific astringent to seal the wound with the sterilized rhizome section of Polygonatum multiflora obtained in step (2), dry it in the shade for one day after sealing, and then dip the wound surface in a mixture of dry plant ash and chlorothalonil powder;

[0022] (4) hide the Polygonatum polyflora rhizome section processed through the closed wound in step (3) ...

Abstract

The invention belongs to the technical field of plant cultivation, and particularly relates to an industrialized breeding method of polygonatum multiflorum seedlings, which comprises the following steps of: cutting all annual white and yellow-white young parts on a rhizome of a polygonatum multiflorum plant into sections, sterilizing and drying in the shade; sealing a wound with an astringent, and dipping the wound surface with mixture dry plant ash and chlorothalonil powder; the young parts are stored in sterilized sandy soil, one layer of river sand and one layer of the rhizome sections ofthe polygonatum multiflorum are subjected to layered germination accelerating, hormone is added into the sandy soil, the rhizome sections with but points and root points are sown into a seedbed, a substrate is used for covering, watering, fertilizing and transplanting are carried out during seedling growing period. According to the invention, the germination time and seedling raising time of thepolygonatum multiflorum are shortened, the propagation times of the polygonatum multiflorum are increased, the diseases of the polygonatum multiflorum are reduced, and the excellent varieties are ensured.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for industrialized breeding of Polygonatum multiflora seedlings. Background technique [0002] Polygonatum cyrtonema (Polygonatum cyrtonema), a perennial herb belonging to Polygonatum cyrtonema in the family Liliaceae, is one of the base plants of Polygonatum cyrtonema, a traditional Chinese medicine. Polygonatum multiflora stems are 50-100 cm high, usually with 10-15 leaves. Leaves alternate, elliptic, ovate-lanceolate to oblong-lanceolate, rarely slightly sickle-shaped, 10-18 cm long, 2-7 cm wide, apex pointed to acuminate. Inflorescence with (1-)2-7(-14) flowers, umbellate, total pedicel 1-4(-6) cm long, pedicel 0.5-1.5(-3) cm long; bracts are tiny, located below the middle of pedicel, Or absent; perianth yellow-green, 18-25 mm long, lobes about 3 mm long; filaments 3-4 mm long, flat or slightly flattened on both sides, with papillae to short h...
