The propagation methods for the medicinal herb Scutellaria baicalensis can be carried out with reference to the following methods:
1. Cuttage propagation. The most suitable period for cuttage is May and June, when the plants are in a vigorous vegetative growth stage. Cut the semi-lignified young tender part from the upper end of the stem and branch (the survival rate is very low when the middle and lower parts of the stem are used as cuttings), cut it into 6-10 cm lengths, then remove the leaves from the lower 2 nodes and keep the upper leaves. The cutting bed is best made of sand, or relatively loose sandy loam will also do. Generally, cut and insert immediately, placing them in the bed at a row spacing of 10 x 5 cm. After insertion, water promptly and set up a shed for shading. Spray water frequently to keep the soil moist, but it should not be too wet, otherwise the cuttings will turn black and rot. With proper management, the survival rate can reach more than 90%, and they can be transplanted 40 days after cuttage.
2. Root division propagation. At harvest time, pay attention to selecting high-yield and high-quality plants, cut off the roots for medicinal use, and leave the rhizome part as propagation material. If digging and harvesting in winter, bury the rhizomes in a cool place indoors and divide and plant the roots again in the second spring; if harvesting in spring, dig and plant immediately, divide the rhizomes into several pieces, each with several bud eyes, and then plant them in the field at a row spacing of 30 x 20 cm. When this method is used for planting on hillside land, the survival rate is relatively high, and management after planting is the same as usual.
