Breeding methods of Scutellaria baicalensis Georgi

Scutellaria baicalensis Georgi is a common traditional Chinese medicine, which is wild in sunny and dry places such as hilltop, hillside, forest edge and roadside. due to the gradual shortage of wild resources, it is now mostly cultivated in most provinces and regions in northern China. Scutellaria baicalensis Georgi propagation methods are cutting propagation, root propagation and seed reproduction, let's take a look!

Cutting Propagation of Scutellaria baicalensis

The most suitable cutting period of Scutellaria baicalensis Georgi is May and June, and the plant is in a vigorous vegetative growth period. cut the young semi-lignified part of the upper part of the stem branch (the middle and lower part of the stem is used as a cuttage with a very low survival rate), cut it to 10 cm long, then remove the leaves of the lower 2 sections, and retain the upper leaves. It is best to use sand in the cuttage, or relatively loose sandy loam. Generally, it should be cut along with cutting, according to the row spacing of 10 × 5 cm in the bed. Watering in time after insertion, and setting up a shed for shade, often spray water to keep the soil moist, but not too wet, otherwise the cuttings will become black and rotten, properly managed, the survival rate can reach more than 90%, and can be transplanted in 40 days after planting.

Root-splitting Propagation of Scutellaria baicalensis

During harvest, Scutellaria baicalensis Georgi should pay attention to select high-yield and high-quality plants, cut off the roots for medicinal use, and leave part of the rhizome for propagation materials, such as digging in winter, burying the rhizome in the shade indoors, and then planting in the second spring, such as digging and planting in the spring, divide the rhizome into several pieces, each piece with several bud holes, and then plant in the field according to the row spacing of 30 × 20 cm. The survival rate of planting in hillside land is higher, and it is the same as general management.

Seed Propagation of Scutellaria baicalensis

1. Direct seeding method: the seed reproduction of Scutellaria baicalensis Georgi is mainly direct seeding, with straight roots, few root forks, good commercial appearance, labor-saving and more direct seeding than in spring. The seeds are generally sown when the ground temperature of 5 cm is stable at 12 ℃-15 ℃, and most of the northern regions are around the first and middle of April.

2. Seedling transplanting method: the seedling transplanting method of Scutellaria baicalensis can save seeds, prolong the growth time, and ensure the whole seedling, but it is labor-consuming. At the same time, the main root of Scutellaria baicalensis Georgi is shorter, the root fork is more, and the appearance quality of the commodity is poor. It is generally used when the seeds are expensive or when direct seeding in dry land is difficult to emerge and protect seedlings.
