How to breed panax notoginseng

Seed propagation: select mature and full seeds from three or four-year-old Panax notoginseng fruits and sow them in winter from 10 to 1 1. After sowing, cover them with a layer of fire mud mixed with fertilizer and then cover them with a layer of turf to promote their seeds to germinate.

The planting spacing is 3×2 inches or 3×3 inches, with 280,000-320,000 seeds per mu, covered with soil for 4-8 minutes, and then covered with a layer of straw after slightly pressing, so as to prevent weeds from growing and moisture evaporation, and prevent rainwater from leaking from the shade shed to damage the border surface and affect the growth of seedlings.

Panax notoginseng must be easy to transplant after growing in seedbed for one year. The transplanted new land must be arranged in the same way as the seedbed, preferably during heavy snow or winter solstice. When planting, cover the soil, the thickness shall be based on not exposing the bud head, not too thick, and then cover with broken grass, the thickness shall be about 0.3-0.5 inch, based on not seeing the soil.

Growth habit

I like warm, cool and humid environment, and I am afraid of cold, heat and water. The soil is loose red soil or brownish red soil, slightly acidic; The annual average temperature is 16.0- 19.3℃.

If the temperature lasts for 3-5 days and the growing period is above 30℃, plants are prone to disease. Dongpo is suitable for farming, with a slope of 5- 15. Planting in low-lying land is prone to root rot.

Farming land should choose sunny hillside. Generally speaking, sandy black loam is the best soil, followed by calcareous soil and red soil. Clay is not suitable for farming. Land selection is one of the important factors for the success or failure of introducing Panax notoginseng. Dongyang should choose a hillside with an altitude of 700- 1500m and a slope of 10-20 degrees.
