Breeding methods of Panax Notoginseng

Seed propagation, mainly by transplanting seedlings.

1. Seed treatment generally selects the seeds of 3-year-old plants with strong growth and no diseases and insect pests. When the fruits are ripe from 11 to 12 months, they are collected and washed, and sown in time. Because the seeds are stored for one week, the germination rate is greatly reduced. Before sowing, seeds were disinfected with 0.2~0.3 Baume sulfur mixture for 10min, or 200~300 times zinc for 15min, and then sown.

2. Sowing seedlings 2~3 months before planting, the selected land will be plowed many times, so that the soil has been fully weathered and finely divided. Before sowing, plough and harrow once more, then raise the ridge height of 18~ 20cm, the ridge width of 1m, apply 3000~ 4000kg base fertilizer every 667m2, mix well with soil, level the ridge surface, open holes according to the row spacing of 6cm×6cm, the hole depth is 1.5cm, put 1 seed in each hole, cover the soil with straw, avoid hardening of the ridge soil. In winter sowing in south China, seedlings emerge in 3 months and emerge in 4 months. About 100,000 seeds (weighing 8.5kg) can be sown per 667 square meters. After one year of cultivation, they are transplanted.

3. Transplanting was carried out from November to December. The seedlings dug out, do not hurt the roots, according to the size of classification, respectively transplanted. The seedlings are disinfected in the same way as the seeds, then holes are opened according to the row spacing of 15cm×12cm, the hole depth is 3 cm, the bud head of the seedling is planted obliquely downward, and then the soil is covered and the grass is covered.
