What are the growth and development characteristics of Panax notoginseng
The seeds of Panax notoginseng have post-ripening and must be preserved under moist conditions in order to complete physiological post-ripening and sprout. Seeds lose their vitality as soon as they are dried. The one-year-old seedlings only had one palmate compound leaf, and the stems and leaves withered in winter. In the second year, new seedlings were produced from the aboveground rhizome around the Spring Equinox.
It is dormant in winter and germinates in the spring of the second year and grows stems and leaves. if the buds are destroyed in the same year, they will not be able to germinate into seedlings in the second year. They need to dormant in the ground for one year, wait for the second year to form new buds, and grow new seedlings in the third spring. Annual plants do not bolting and blossom, most biennial plants bolting and flowering, but less fruit, three-year-old plants generally blossom and bear fruit.

Cultivation techniques of Panax Notoginseng
Panax notoginseng was propagated by seeds. The seeds of three-year-old plants were selected and collected when a large number of fruits matured and turned red from November to December. Remove the pericarp and sow the mature and pest-free seeds in winter immediately. If it is too late to sow, the fruit should be spread out in a sieve, about 3 cm thick, and can be stored in a ventilated and cool place for 7 to 10 days. For outward transportation, the pericarp should be removed, cleaned, mixed into 2 times wet sand and stored in wooden boxes.
