Efficacy and function of rhodiola sachalinensis 1 Two-way regulation of human health depends on the environmental balance in the body, that is, the balance of yin and yang. Rhodiola can mobilize all positive factors in the body, and has a two-way regulation effect of tonifying deficiency and reducing excess. Through self-regulation of metabolic system, circulatory system, nervous system, endocrine system and immune system, the body can reach the best state, and the blood pressure, hemoglobin, hemoglobin, blood sugar and cardiovascular and cerebrovascular functions in the body can be restored to normal levels.
2. Effectively regulating the nervous system can effectively eliminate people's nervousness, balance the central nervous system, improve sleep and irritability or depression, improve energy and enhance memory. Can refresh the brain, improve intelligence, reduce error rate, improve work and study efficiency, and prevent Alzheimer's disease.
3. Anti-fatigue and overall immunity enhancement: Rhodiola can enhance cellular immunity, humoral immunity and nonspecific immunity, and enhance the activity of macrophages and natural killer cells, thus improving the disease resistance and infection resistance of human body. It has cardiotonic effect, can increase the duration of normal activities of brain and body, and prolong the load capacity of brain nerves and body muscles. When tired, it can accelerate the decomposition of fat and protein and increase energy transfer; After overwork, the reserves of muscle glycogen and liver glycogen can be increased. It has obvious effect on preventing and treating fatigue syndrome and keeping human body vigorous for a long time.
5. Enhance cardiovascular and cerebrovascular functions: Rhodiola can reduce the load on the heart, improve the heart function, enhance the pumping function of ischemic heart and accelerate blood flow. Rhodiola has the functions of invigorating qi, promoting blood circulation, removing blood stasis, removing vascular garbage, increasing hemoglobin content, improving blood oxygen content, protecting myocardial hypoxia, repairing damaged myocardial cells, reducing myocardial infarction area and restoring heart vitality, etc., which is superior to compound salvia miltiorrhiza.
6. Effect on human smooth muscle: Asthma is caused by smooth muscle spasm. Rhodiola can effectively relieve smooth muscle spasm, regulate defecation, and has obvious preventive and therapeutic effects on asthma, tracheitis, excessive phlegm, constipation and other diseases.
7. Effect on Rheumatoid Arthritis Rheumatoid arthritis is caused by wind, cold and dampness. A large number of clinical evidences prove that Rhodiola has the effects of expelling wind, keeping out cold and relieving pain, especially for joint swelling.
8. Anti-fatigue, anti-hypoxia and anti-aging: Rhodiola can effectively eliminate fatigue, restore physical strength and make the body full of vitality by removing lactic acid and supplementing blood oxygen. Rhodiola sachalinensis can improve the aerobic metabolism process of the body during hypoxia on the whole level, and has a protective effect on myocardial cells damaged by hypoxia. Rhodiola has a strong antioxidant capacity, which can effectively scavenge free radicals, delay the aging of cerebral cortex, and also have an anti-aging effect on skin.
Cultivation techniques and site selection of Rhodiola sachalinensis
Rhodiola sachalinensis is generally wild in sunny slopes, crevices, alpine meadows, alpine rock crevices, the morphology of Rhodiola sachalinensis in hillside grasslands, scrub edges and alpine dry sand. It has strong adaptability, likes a slightly cool and humid climate, is cold-resistant and drought-tolerant, and has not strict requirements on soil. It is suitable for cultivation in mountainous areas with high altitude, cool climate, short frost-free period in summer and large temperature difference between day and night.
The cultivation land should be loam or sandy loam with rich humus, deep soil layer, sufficient sunshine and good drainage, and forest cutting land or raw wasteland in mountainous areas can be used for cultivation.
It is best to choose plots with fertile and loose soil and close to water sources.
As far as possible, the transplant site should be selected in hillside, barren slope and non-cultivated land with good drainage and slightly more sediment in soil, and it is not suitable for planting in clay, saline-alkali land and low-lying waterlogged land.
Soil preparation and fertilization
After land selection, dig 30~40cm deep, remove impurities in the field, break clods, and make ridges along the slope direction, with a width of 100~ 120cm, a height of 20~25cm, and a working road width of 50~70cm. Combined with cultivated land, manure or pigsty fertilizer is applied to 30,000 ~5 hectares. Ridges can be ridged on the flat land with higher terrain, and can also be ridged on the land with lower terrain. Non-arable land on slopes and hillsides should only be plowed without harrowing or ridging, but drainage ditches should be dug.
grow seedlings
Selecting fresh and mature Rhodiola seeds for spring sowing or autumn sowing, wherein the spring sowing time is from late March to early April, and the autumn sowing time is from mid-September to before freezing. Sowing in autumn, early emergence, complete seedlings, seeds do not need to be treated.
When sowing in spring, the seeds should be soaked in water. The specific method is: put the seeds into a clean cloth bag, soak the cloth bag with normal temperature water for 40-50h, change the water 2-4 times a day, dry the soaked seeds in a cool and ventilated place, remove the surface moisture, and sow immediately when the seeds can disperse naturally. When sowing, the soil on the surface of the seedbed should be leveled with wooden boards, and the ditch should be dug horizontally with a row spacing of 8~ 10cm, and the depth of the ditch should be 3 ~ 5 mm The seeds should be evenly scattered in the ditch, and the sowing amount should be per square meter 1. 5~2。 0g, cover the sieved fine soil for 2~3mm, compact it with hands or wooden boards, and then cover the bed with a layer of straw or pine branches for moisture retention.
transplant
Transplanting rhodiola sachalinensis seedlings after growing 1 year, and the transplanting time is after the overground part withers in autumn of that year or before turning green in spring of the following year. The effect of transplanting in spring is better. Generally, it is carried out from late March to early April when the seedlings have not germinated. First, dig out all the seedlings and transplant them in different grades according to the planting size. The planting row spacing is 20cm, the plant spacing is 10~ 12cm, and the horizontal furrow is dug, and the furrow depth is 10~ 12cm. The terminal bud is planted upward in the ditch and covered.
Harvest processing
After the overground part withers in autumn during the harvest season, the withered stems and leaves of the overground part are removed, the underground part is dug out, the soil is removed, washed with clear water, and dried at 60-70℃, or the washed medicinal materials are steamed in a pot for 7- 10 minutes, and then dried or put in a drying room. When the medicinal materials are 70% to 80% dry, straighten the roots and rhizomes, align the tops and count.
Eliminate pests and diseases
The disease mainly occurs in the incision of rootstock propagation seedlings, which is easy to form root rot, and can be prevented by disinfection and sterilization before planting. The pests are mainly LEPIDOPTERA pests, such as aphids and butterflies, which are controlled by spraying 3% hypertonic fenoxycarb EC0.025%~0.033% solution.
