Embodiment approach

[0019] Implementation method: a breeding method for Polygonatum polygonatum with high stress resistance, which is special in that: dig wild Polygonatum, mix and cultivate multiple candidate varieties under the same site conditions, and then simulate or create drought and waterlogging And one or more harsh environments in weeds, diseases and insect pests are screened for the first resistance, and then the second resistance selection is carried out, and the Polygonatum high stress-resistant varieties are selected.

[0020] The mixed cultivation: including site selection, site preparation, compartment ditching, seed selection, planting,

[0021] Further, the selection: first sort and number the excavated wild sealwort according to the type of rhizomes, then remove the necrotic, insect-pest, and diseased rhizomes respectively, keep the root hairs, select the rhizomes with bud heads, and cut the rhizomes close to the bud heads. The first three sections of the part are dried until t...

Embodiment 1

[0031] Embodiment 1: A kind of breeding method of Rhizoma Polygonatum with high resistance to stress, excavating wild Rhizoma Polygonatum, mixing and cultivating at least 2 candidate varieties under the same site conditions, and then simulating drought, waterlogging, weed damage, plant diseases and insect pests After the first screening of one or more hostile environments, the second screening of resistance is carried out, and the varieties with high stress resistance and high yield of Huang Jing are selected.

Embodiment 2

[0032] Embodiment 2: a kind of breeding method of Rhizoma Polygonatum with high resistance to stress, select the highland sandy loam soil with sufficient light and easy to drain, the area is 1 mu, the land is plowed more than 30cm, the compartment is ditched, and the width of the compartment is 1.2 meters, ditch width 30cm, ditch depth 30cm, and open drainage ditch around, drainage ditch width 40cm, depth 40cm. Wild Polygonatum will be excavated from the summer festival to the beginning of winter festival, and 7 varieties will be selected according to the rhizome shape, numbered 1#, 2#, 3#, 4#, 5#, 6#, 7#, and then respectively Remove the rhizomes that are necrotic, infested with insects, and diseased, keep the root hairs, select the rhizomes with bud heads, cut off the first three nodes near the bud heads, dry them until the cut surface shrinks, put them in boxes according to varieties, and store them for up to 10 days for later use. 7 kinds are sown by compartment cross layo...

Abstract

The invention relates to screening of rhizome medicinal material varieties, in particular to a breeding method of a high-stress-resistance variety of polygonatum sibiricum. The breeding method is characterized by comprising the steps that wild polygonatum sibiricum is dug, mixing cultivation is carried out on multiple alternative varieties under a same site condition, then one or more resistance environments of drought, waterlogging, weed damage and pest and disease damage are simulated or created for first resistance screening, then second resistance screening is carried out to breed the high-stress-resistance variety of polygonatum sibiricum. According to the breeding method of the high-stress-resistance variety of polygonatum sibiricum, various stress resistances of different wild polygonatum sibiricum varieties can be shown, thereby screening the high-stress-resistance variety of polygonatum sibiricum with one or more characteristics of drought resistance, waterlogging resistance,weed damage resistance and pest and disease damage resistance, and the suitable good variety is provided for polygonatum sibiricum cultivation under different site conditions.

Description

technical field [0001] The invention relates to a screening method of varieties of rhizome medicinal materials, in particular to a breeding method of Polygonatum high resistance varieties. technical background [0002] Polygonatum sibiricum (Latin scientific name Polygonatum sibiricum) is a perennial herb of Liliaceae, whose rhizome is used as medicine. It has the functions of invigorating qi and nourishing yin, nourishing the lungs and strengthening the spleen, nourishing the kidney and replenishing essence, enhancing immune function, and delaying aging. Polygonatum is mostly born in shrub forests or barren hills and slopes. It likes dampness and cold resistance, and can grow in both north and south. With the thirst of the wild resources of sealwort, the artificial cultivation of sealwort gradually rises. But the provenance of existing sealwort artificial cultivation, mainly gathers from wild. Due to the variety of wild Polygonatum resources, the stress resistance varies...
