When will Panax notoginseng be harvested?

Question 1: When will Panax notoginseng be harvested? Panax Notoginseng is also known as Kaihua Panax Notoginseng, Panax Notoginseng, Panax Notoginseng, and Jinbu Huan. Plant form: Perennial herb, up to 60cm tall. The rhizome is short, the stem is upright, smooth and hairless. Palmately compound leaves with long stalks, 3 to 4 whorls on the top of the stem; 3 to 7 leaflets, oval or oblong-ovate, with finely serrated edges. The umbels are terminal, and the peduncle is drawn out from the center of the stem top, 20 to 30cm long. The flowers are small, yellow-green; the calyx is 5-lobed; the petals and stamens are both 5-lobed. The drupe is berry-like, nearly kidney-shaped, and red when ripe. Seeds 1 to 3, oblate spherical. The flowering period is from June to August, and the fruiting period is from August to October. Nowadays, it is mostly cultivated on mountains with an altitude of 1600-1800m. The main place of origin (origin) is Wenshan, Yunnan. Nature and flavor: Warm in nature, sweet and slightly bitter. Efficacy: (1) It has good hemostatic effect and significant hematopoietic function; (2) It can strengthen and improve coronary microcirculation and dilate blood vessels; (3) It has strong analgesic effect, anti-fatigue, and improves learning. and memory ability; (4) Anti-inflammatory effect; (5) It has the effect of immunomodulator, which can restore the immune response that is too high or too low to normal, but does not interfere with the normal immune response of the body; (6) Anti- Tumor effects; (7) Anti-aging and antioxidant effects; (8) Reduce blood lipids and cholesterol; (9) Protect the liver. Panax notoginseng originated in the Tertiary Period and is a relict plant of the ancient tropics. Its distribution range is extremely narrow. This is mainly related to the physiological and ecological adaptability of Panax notoginseng to the environment. Panax notoginseng is a perennial herbaceous plant with an annual growth cycle. Usually, Panax notoginseng that is more than two years old has two growth peaks in one growth cycle, the vegetative growth peak from April to June and the reproductive peak from August to October. The germination temperature of Panax notoginseng seeds is 10-30 degrees, and the optimal temperature is 20 degrees. The dormancy period of the seeds is 45d-60d. During the dormant process, the seedlings need a period of low temperature treatment before they can germinate, and their response to light Very sensitive; it is traditionally believed that 30% of natural light is needed for normal growth and development, so the Panax notoginseng shade shed has a saying of "30% light transmission, 70% shade"; according to the latest research, the most suitable Panax notoginseng shed has a light transmittance of 8 %-12%. If it exceeds 17%, the growth of Panax notoginseng will be adversely affected. It takes more than 3 years from sowing to harvesting of Panax notoginseng; the roots of annual Panax notoginseng are usually used as seedlings, and they can bloom and bear fruit from the second year of the plant. Buds usually appear in July, bloom in August, and bloom in September. Fruity, fruits mature in batches from October to November. The main Panax notoginseng production area in Yunnan Province is located on a low-latitude plateau. The climate is characterized by long summers and warm winters, relatively abundant heat, and relatively small annual temperature differences. The annual average temperature is 15.8-19.3°C (Yunnan Meteorological Bureau Data Room, 1982). Except for the weather with daily low temperature ≥0.0℃ from mid-December to mid-February of the following year, the average minimum temperature for many years is 0-2℃, and the number of days with stable daily average temperature ≥10℃ over the years is 265-307 days, and the annual effective accumulated temperature reaches 4863.7-6436.8℃. In summer, due to concentrated rainfall, solar radiation drops significantly, resulting in an average temperature of 21.5-22.5°C from June to August. Suitable temperature and moisture conditions provide a superior natural environment for the growth and development of Panax notoginseng. The average monthly temperature in winter is 11°C, and the growth of the above-ground parts has stopped. However, at this time, the 5cm ground temperature still remains at 14°C (regional average). This is the reason why the stems and leaves of Panax notoginseng can still maintain vitality in winter. The higher ground temperature, It is beneficial to the accumulation of nutrients in the roots, especially for the post-ripening morphological development of the seed embryos that have been sown into the soil. The post-ripening stage of the seed embryos can be completed naturally during the winter stage. This is beneficial to the seedling raising work of Panax notoginseng and improves the emergence of seeds. rate, providing extremely favorable conditions. Such a unique natural ecological environment is a favorable factor for Wenshan Prefecture to develop Panax notoginseng production. The topography of the Panax notoginseng production area is complex and the terrain is undulating, resulting in significant vertical differences in temperature. Winter and spring (December to April) and late summer and early autumn (August to October) are affected by the invasion of cold air from the atmospheric circulation. , resulting in short-term and local frost and low temperature disasters, especially low temperature damage. Although there was no snowfall or frost, and the temperature did not drop to the 0°C frost value, the temperature suddenly dropped below the critical value for crop growth (weekly Yiren et al., 1980) cause greater harm, and this kind of situation may occur almost every few years. In the production areas with an altitude of less than 500m in Funing County, the temperature is higher in summer. Coupled with the foehn effect and local circulation, the temperature tends to increase. Weather with the daily maximum temperature ≥35℃ may occur, and evaporation will be strengthened, which is likely to cause The plants are wilted. The above two... >>

Question 2: When is the harvest season for Panax notoginseng in Yunnan? The picking season for Panax notoginseng flowers is from July to August. The flowers are picked without leaving seeds. Those excavated around August are called Spring Panax notoginseng, and those plucked around the Spring Festival are called Winter Panax notoginseng.

Question 3: When does Panax notoginseng mature? Panax notoginseng is a perennial herbaceous plant with an annual growth cycle. Usually, Panax notoginseng that is more than two years old has two growth peaks in one growth cycle, the vegetative growth peak from April to June and the reproductive peak from August to October.
