Problems solved by technology

Due to the difficulty in collecting the seeds of Rhizoma Polygonatum, the germination rate is low, and the growth cycle of seedlings is long, which increases the cost of production and planting, which is not conducive to the promotion of planting in large areas.
The method of rhizome propagation has a low reproduction coefficient, and the large amount of rhizomes used is not economical, but also limits the scale of production and planting. The problem of seedlings has become a bottleneck restricting the large-scale artificial planting of Rhizoma Polygonatum.
At present, the field intensive planting technology for Polygonatum yunnanensis is not perfect, and most of them are planted in small quantities by growers, with a low degree of intensification

Embodiment 1

[0065] Embodiment one: tuber seedling field intensive planting

[0066] 1 tuber seedling cultivation

[0067] Choose robust, yellowish color, no pests and diseases, no broken skin, and tubers with terminal buds as seedling tubers. Cut the tender part of the apex of Polygonatum yunnanensis tuber into several sections, each section has 2 nodes and 1 to 3 bud eyes. Soak the cut Rhizoma Polygonatum tubers with 30% metalaxyl water for about 5 minutes to form a protective film on the surface of the tubers, and dry them for later use. The treated Rhizoma Polygonatum tubers were planted on the sand bed, and the sand bed was kept moist. The emergence of the tubers was investigated 30 days after planting, and statistics were made once a week thereafter.

[0068] 2 Intensive Planting of Polygonatum Polygonatum in Field

[0069] 2.1 Environmental condition control

[0070] Altitude: The planting site should be in an area with an altitude of 700-3600m and convenient transportation.

Embodiment 2

[0098] Embodiment two: Tissue cultivation field intensive planting

[0099] 1 Tissue culture of Polygonatum yunnanensis

[0100] 1.1 Extraction of explants

[0101] From September to October every year, the rhizome buds of Rhizoma Polygonatum plants that have been domesticated and cultivated, are good in growth, large in size, and free from diseases and insect pests are selected as explant materials. .

[0102] 1.2 Disinfection of explants

[0103] When in use, the surface of the Rhizoma Polygonatum Rhizome is brushed with 1% washing powder, rinsed under running water, and the pretreated tuber is cut into small pieces with buds on an ultra-clean workbench to obtain the explant material. The explant material disinfection procedure is as follows:

[0104] (1) 75% alcohol for surface disinfection, disinfection time is 20s;

[0105] (2) Wash with sterile water 2 to 3 times;

[0106] (3) 0.1% mercuric chloride is used for deep disinfection, and the disinfection time is 15 min...

Embodiment 3

[0118] Embodiment three: Exploration of the best disinfection program for tuber seedling cultivation

[0119] 1 tuber of choice

[0120] Choose robust, yellowish color, no pests and diseases, no broken skin, and tubers with terminal buds as seedling tubers.

[0121] 2 tuber treatments

[0122] The biggest problem in the tuber cultivation of Polygonatum yunnanensis at present is that the tubers are easy to rot, resulting in low emergence rate and low quality of seedlings. The purpose of this experiment is to disinfect the tubers of Polygonatum yunnanensis and screen out the best treatment plan, so as to reduce the rot rate of tubers and improve the emergence rate and seedling quality.

[0123]Cut the tender part of the apex of Polygonatum yunnanensis tuber into several sections, each section has 2 nodes and 1 to 3 bud eyes. Carry out the following three disinfection treatments on the tubers:

[0124] Treatment 1: Soak the cut Rhizoma Polygonatum tubers in 1:800 carbendazim ...

Abstract

The invention relates to the technical field of medicinal plant planting, in particular to a field intensive planting method capable of realizing rapid propagation and used for polygonatum kingianum.At present, as the planting technology of polygonatum kingianum is immature, most planting methods are summarized by planters according to experience and are not systematic or specialized. According to the method, the disinfection procedure of tuber seedling culture, explant picking time of tissue culture seedling culture, disinfection method, culture medium components and proportion and other culture parameters are optimized through seedling culture tests, a seedling culture method capable of realizing high germination rate and small rotting rate is explored, in combination with the field intensive planting method used for the polygonatum kingianum, the seedling culture time of the polygonatum kingianum is greatly shortened, and mass standardized planting of the polygonatum kingianum is realized.

Description

technical field [0001] The invention relates to the technical field of planting medicinal plants, in particular to a rapid-propagation field intensive planting method of Polygonatum yunnanensis. Background technique [0002] Polygonatum kingianum Coll. et Hemsl is a herbaceous plant of Polygonatum kingianum Coll. et Hemsl, whose rhizome is nearly cylindrical or nearly bead-shaped, and the nodules are sometimes irregularly diamond-shaped and hypertrophic. Berries red, 1-1.5 cm in diameter, with 7-12 seeds. The flowering period is March-May, and the fruiting period is September-October. According to the "Chinese Pharmacopoeia" 2015 edition, the traditional Chinese medicine Polygonatum Polygonatum is the dried rhizome of Polygonatum Polygonatum, Polygonatum Polygonatum or Polygonatum Polyflora. Polygonatum Polygonatum is one of the basic varieties of Polygonatum, its rhizome is relatively thick, and it is one of the best quality varieties of Polygonatum medicinal materials. ...
