Propagation methods of Salvia miltiorrhiza

Seed reproduction:

It is generally used for sowing, and it is best to sow seeds from Grain in Beard to the Summer Solstice and the End of Heat to White Dew in the year of seed collection. The seedbed should choose land with slightly higher topography, loose and fertile soil and convenient watering. In order to raise seedlings in the mountain area, it is best to choose the hillside slope facing east or southeast as a nursery bed to reduce the sun and facilitate seedling emergence. The seedbed was ploughed first, and the retting human feces and urine was used as the base fertilizer. The soil should be fine and make a high border, 1.3 to 1.66 meters wide. Then sow the seeds evenly and shallowly on the border surface, tread lightly with your feet after sowing, make the seeds close to the topsoil (no need to cover the soil), cover with a thin layer of wheat stalk, and often sprinkle water to keep moist. When the seedling has 3-5 true leaves, if it is found that it is too dense, the seedlings should be interspersed. The seedlings can be planted and cultivated separately. During this period, attention should be paid to watering, and rarefied human feces and urine should be applied twice in time to promote the growth of seedlings. The suitable transplanting time is from late October to early November of that year. Before transplanting, the holes were opened with a distance of 25 cm × 25 cm on the surface of the border, which depended on the length of the root of the seedling. Plant 1-2 plants per hole, planting depth to slightly exposed heart buds, not too deep, and do not expose the roots. After planting, cover the soil to the flat point, compact slightly, and water the root in time. Salvia miltiorrhiza transplant early, take root early, already survive when the cold winter comes, turn green early next year, try not to postpone the transplant until the cold season as far as possible.

Split root propagation:

From the Beginning of Spring to the wake of the sting. A new root with a diameter of about 1 cm is selected for planting. Before planting, cut the root into 5-7 cm long root segments. The planting density is 27 cm between rows and 20 cm between plants. Open a groove on the border surface, put the root section directly in the ditch, pay attention to the upper and lower ends are not inverted, and cover the soil after planting. Seedlings usually emerge after Grain Rain. Split root propagation, flowering later, it is difficult to receive seeds, but the root growth is faster.

Ramet propagation:

From the beginning of winter to the second year, when the salvia miltiorrhiza was harvested at home (usually between the Winter Solstice and the Beginning of Spring), the sturdy and disease-free plants were selected, the thick roots were cut off for medicinal use, and the roots with heart leaves which were thinner than cigarettes were used as seedlings for planting. Wild Salvia miltiorrhiza can also be dug and transplanted with roots and seedlings. Large seedlings can be divided into 2-4 plants according to the natural growth of buds and roots, and then planted.

Cutting method:

Before and after the Qingming Festival, choose a sturdy stem, cut it into 2 or 3 segments, cut off some of the leaves, cut them into the whole border, and bury them 6cm into the ground, so that the buds are slightly exposed, the soil is compacted and watered immediately. After that, spray water with a sprayer in the morning and evening to keep the border moist.
