What are the methods for selecting and raising Scutellaria baicalensis seeds?

Scutellaria baicalensis is a perennial herb of the genus Scutellaria in the Lamiaceae family, also known as Shancha root, Tujincha root, etc. Its root is used as medicine and has effects such as clearing heat and drying dampness, purging fire and detoxifying, stopping bleeding, and calming the fetus. Its antibacterial properties are better than those of Coptis chinensis, and it does not produce drug resistance, so market demand is very large and its cultivation value is very high. So how do you select Scutellaria baicalensis seeds? What are the seedling-raising methods? Now let's take a look together with the editor.

1. How do you select Astragalus seeds?

When planting Astragalus, choose seeds with good appearance and quality, and eliminate seeds that are moldy, not plump, or have been stored for too long.

After selecting good Scutellaria baicalensis seeds, soak them in warm water at 40-45°C for 5-6 hours or in tap water at room temperature for 12-24 hours, remove them and let them dry slightly, then keep them moist at about 20°C to promote germination. Once some seeds have cracked and sprouted, they can be sown.

2. What are the seedling-raising methods for Astragalus?

1. Sowing time

Scutellaria baicalensis is generally sown in spring from March to April, or in autumn from September to October. When soil moisture is guaranteed, it is best around mid-April when the soil temperature at 5 cm underground is stable at 15°C. The sowing methods are broadcast sowing, dibbling, and drilling, and it is better to sow shallowly rather than deeply.

2. Seedbed selection

For Scutellaria baicalensis, where direct sowing on dry hillside land makes it difficult to preserve seedlings, the seedling transplanting method can be used. For seedling raising, choose a warm place with sufficient sunlight as the seedbed. Either a sunny bed or a hotbed can be used, with a width of 130-135 cm, and the length depending on need.

3. Seedling stage management

After the Scutellaria baicalensis seedlings emerge completely, ventilate appropriately. When the seedlings are 3 cm tall, remove the film, and weed and thin the seedlings in time. When the seedlings are 5-7 cm tall, transplant them into the field at a row spacing of 40-45 cm and a density of 25-30 plants per meter of length, and water promptly after transplanting.

4. Harvesting and processing

Scutellaria baicalensis is best harvested 2-3 years after sowing. The harvest season is in late autumn or before spring sprouting. When harvesting, dig carefully and never break the roots. After digging them out, shake off the soil, sun-dry until half dry, remove the outer skin, and then quickly sun-dry or oven-dry.

The above is an introduction to Scutellaria baicalensis. After sowing and until emergence, the soil should be kept moist. From emergence to final thinning, loosen the soil and remove weeds in time. There is now relatively high demand for Scutellaria baicalensis on the market, and its planting prospects are broad.
