Embodiment 1

[0017] Embodiment 1: A kind of breeding method of Polygonatum multiflora, excavating multiple wild Polygonatum multiflora, mixing and cultivating the above-mentioned wild Polygonatum multiflora under the same site conditions, the planting density per mu is 850-1000 plants; then simulate or Create one or more severe environments of drought, waterlogging, weed damage, plant diseases and insect pests to carry out a comprehensive screening; among them, the simulated drought: no sunshade, no watering, no cover on the box surface, so that the water shortage rate of Polygonatum seedlings is 35%. %≦DW≦50%, continuously maintained for 1 to 2 months; simulated waterlogging: do not open moisture ditch, pour water into the field, so that water can be seen in the sub-ditch all year round; create a weed damage environment: let the weeds grow It grows naturally, creating a weedy environment; creating an environment for pests and diseases: no human intervention is made for any pests and diseas...

Embodiment 2

[0019] Embodiment 2, a breeding method of Polygonatum multiflora, excavating a variety of wild Polygonatum multiflora, mixing and cultivating the above-mentioned wild Polygonatum multiflora of multiple alternative varieties under the same site conditions, and then simulating or creating drought, water One or more severe environments in waterlogging, weed damage, disease and insect pests are subjected to a comprehensive screening; among them, simulated drought: no sunshade, no watering, no cover on the side of the car, so that the water shortage rate of Polygonatum seedlings is 35%≦DW≧ 50% for 1 to 2 months; simulated waterlogging: do not open moisture ditches, but pour water into the field, so that water can be seen in the subdivision ditch all year round; create a weed damage environment: let the weeds grow naturally, Create a weedy environment; create an environment for pests and diseases: no human intervention in any pests and diseases that occur.

Embodiment 3

[0021] The difference between Example 3 and Example 1 is that when the rhizomes are sterilized, they are first put in a disinfectant solution for disinfection, then washed twice with deionized water, rinsed with ethanol for half a minute, washed off with water, and finally sterilized with a disinfectant solution. Bacteria for five minutes, and then washed three times with water, the disinfectant used is thiamethoxetine, Zhongshengmycin and Abi-Chlorothalonil soaked in 400 times of liquid for disinfection treatment, and the treatment time is 30 minutes.

Abstract

The invention discloses a breeding method of rhizoma polygonati in the technical field of cultivation of traditional Chinese medicinal materials. Wild rhizoma polygonati is collected and dug, multiplecandidate varieties are mixed and cultivated under the same site condition, and then one or more resistant environments such as drought, waterlogging, weed damage and disease and pest damage are simulated or created for primary resistance screening; the roots and stems of the selected varieties are sterilized first, and then the parts with buds at the ends are selected as a provenance, after seedlings raising, a field comparison test is carried out, after traditional steaming and drying of tubers, in combination with the determination of effective ingredients total saponins and polysaccharidecontent, the rhizomes with the total saponins content of active ingredient indexes of 12 mg/g or above or the polysaccharide content of 14 mg/g or above are selected as mother species and cultivatedcontinuously for 2-4 years, and the total saponins content and polysaccharide content of the cultivated rhizomes are 90% or higher of the effective ingredient indexes; and then a one-year evaluation planting test is carried out to select the variety with the highest total saponin content and polysaccharide content after addition to obtain a breeding variety with the highest effective medicinal ingredients.

Description

technical field [0001] The invention relates to the technical field of cultivation of Chinese medicinal materials, in particular to a breeding method of Polygonatum. Background technique [0002] Polygonatum Polygonatum is a perennial herb of Liliaceae, whose rhizomes are used as medicine. It has the effects of invigorating qi and nourishing yin, moistening lung and strengthening spleen, nourishing kidney and essence, enhancing immune function, delaying aging, etc. It is effective in treating diabetes, hypertension, cardiovascular disease, tuberculosis, chronic hepatitis, etc. , anti-aging and other aspects have good effects, so it is widely used. Along with the depletion of wild sealwort resources, the artificial cultivation of sealwort has gradually emerged. The provenance of the existing sealwort artificial cultivation is mainly collected from the wild, but the wild sealwort resources are mixed and varied in stress resistance. Even in the same planting conditions Under ...
