What are the propagation methods for Panax notoginseng? Teaching you to grow Panax notoginseng correctly

Propagation is by seed, mainly using seedling raising and transplanting.

1. Seed treatment: generally select seeds produced by 3-year-old plants that are robust and free of pests and diseases. When the fruit matures from November to December, harvest it, wash off the flesh, and sow promptly, because after the seeds are stored for one week, the germination rate drops greatly. Before sowing, disinfect the seeds with 0.2-0.3 degrees Baume lime-sulfur mixture for 10 min, or with 200-300 times zineb for 15 min, then sow.

2. Sowing and seedling raising: 2-3 months before planting, plow the selected land repeatedly so that the soil is fully weathered and finely broken up. Before sowing, harrow once more, then make beds 18-20 cm high and 1 m wide, apply 3000-4000 kg of base fertilizer per 667 sq m, mix it evenly with the soil, level the bed surface, and open holes at a plant and row spacing of 6 cm×6 cm, with a hole depth of 1.5 cm. Place 1 seed in each hole, cover with soil, and then cover with rice straw to prevent the bed soil from crusting. For winter sowing in the south, seedlings emerge in 3 months and are complete in 4 months. About 100,000 seeds can be sown per 667 sq m (weighing 8.5 kg). After one year of cultivation, they are ready to leave the nursery for transplanting.

3. Transplanting: transplanting is carried out from November to December. Dig out the seedlings, being careful not to damage the roots, grade them by size, and transplant them separately. First disinfect the seedlings by the same method as the seeds, then open holes at a row and plant spacing of 15 cm×12 cm, with a hole depth of 3 cm, plant the seedlings diagonally with the buds facing downward, then cover with soil and straw.
