specific Embodiment approach 1

[0067] Specific implementation mode 1: In this implementation mode, four years of breeding of Rhodiola rosea cultivars in low-altitude plain areas is a production cycle, and the border cultivation is completed according to the following steps:

[0068] First year of breeding:

[0069] (1) Land selection: select the land where the last chemical weeding time is corn or soybean before the end of June, and plow the land in autumn;

[0070] (2) Make a furrow: After the ground is leveled, open a footpath to make a furrow to obtain a seed bed. The soil on the furrow surface is as thin as a surface and the ground is as flat as a mirror. The width is 60 cm, and the direction of the furrow is north-south;

[0071] (3) Seed soaking: wash the Rhodiola rosea seeds, put them into a clean cloth bag, soak them in tap water for 5 days, and let them dry;

[0072] (4) Seed dressing: pass the river sand through a sieve with a pore size of 2 mm, wash with water and dry in the sun, then soak in b...

specific Embodiment approach 2

[0097] Specific embodiment two: the difference between this embodiment and specific embodiment one is: field planting is to adopt ridge planting to replace bed planting, and the ridge spacing of ridge planting is 60 centimetres, double row on the ridge, triangular planting method, and plant spacing 30 centimeters. Other steps and parameters are the same as in the first embodiment.

[0098] The ridge of the present embodiment is compared with ck (referring to land sowing, the sowing area without any mulch is compared) the withering number reduces 90.7%; The ridge height increases 33% than ck; The ridge number increases 121% than ck %; the fresh weight of roots in ridges increased by 37.7% compared with ck; the fresh weight of whole plants in ridges increased by 50% compared with ck.

[0099] The mode and method of this implementation The Rhodiola rosea seedling emergence rate reaches 90.5%, the variety purity reaches 100%, and no root rot occurs. The content of sedroside in 4-...

specific Embodiment approach 3

[0100] Specific implementation mode three: this implementation mode is different from specific implementation mode one in that: the selection of plots in the first year of breeding selects the standard high-yield plots that can be irrigated by drought and can be drained by waterlogging, and plow the ground in autumn.

[0101] Other steps and parameters are the same as in the first embodiment.

[0102] The mode and method of this implementation The Rhodiola rosea emergence rate reached 90.9%, the variety purity reached 100%, and no root rot occurred. The content of sedroside in 4-year-old Rhodiola rosea was 0.88%. Compared with the method of not cutting the stems and leaves, the yield of rhizomes was reduced by 28%.

Abstract

The invention belongs to the field of rhodiola sachalinensis cultivation and provides a method for cultivation of an improved variety of rhodiola sachalinensis in a low-altitude plain area. The method aims to solve the technical problems that in the process of cultivation of the rhodiola sachalinensis, root rot is prone to occurrence, the rate of emergence of seeds is low, and the yield is low. According to the method for cultivation of the improved variety of the rhodiola sachalinensis in the low-altitude plain area, a production cycle lasts for four years, a sowing plate is used for sowing, a bed surface is covered with pine needles and a mulching film, a shading net is erected on a bed, and weeding is conducted in time; in the next year, field planting is conducted, and organic compound fertilizer and farmyard manure which is processed through ferment bacteria are applied additionally; in the third year, after the seeds are harvested, stems and leaves above the ground are cut off, and field cultivation, vegetative propagation and other measures are taken; in the fourth year, fertilization is conducted from early May, and other aspects are managed according to the third year. By means of the method, the rate of emergence is over 90.5% which is more than three times that of common seeds which are sown, the morbidity of root rot is below 0.01%, the purity of the seeds is up to 100%, and the content of salidroside is up to 0.88%.

Description

technical field [0001] The invention belongs to the field of rhodiola cultivar breeding, and in particular relates to a breeding method for rhodiola cultivars in low-altitude plain areas. Background technique [0002] Rhodiola sachalinensis (Rhodiola sachalinensis), also known as Rhodiola alpine, was named Rhodiola alpine in the "Northeast Flora" compiled by the Shenyang Forestry Institute of the Chinese Academy of Sciences in 1980. In 1984, the Chinese Academy of Sciences and the Editorial Committee of Flora of China In "Flora of China", the alpine Rhodiola was changed to Sakhalin Rhodiola. It is a perennial herbaceous plant of the genus Rhodiola in the Crassulaceae family. Kuye Rhodiola is a rare Chinese herbal medicine. You can find Chinese herbal medicines that are rarer than ginseng, antler, cordyceps, tiger bone and musk on the Internet. In my country’s first medical classic "Shen Nong’s Materia Medica", you will find that Rhodiola is impressively Listed as "the top g...
