Detailed Explanation of Scutellaria baicalensis Planting Experience and Technical Key Points
Scutellaria baicalensis is a perennial herb of the Lamiaceae family, with medicinal roots and rhizomes. The whole plant is 30-60 cm tall, with a thick main root. It is distributed wild in most parts of the country and has strong adaptability, able to grow in ordinary soil. It has the effects of clearing heat and drying dampness, stopping bleeding and calming the fetus.
I. Site selection and land preparation: For planting, sandy or semi-sandy soil is preferable, and irrigation conditions are needed. Generally, sufficient base fertilizer is applied before planting, mainly barnyard manure, or 30 kg of nitrogen-phosphorus-potassium fertilizer, with more phosphorus and potassium fertilizer applied (according to the usual amount of base fertilizer used for planting wheat). For broadcasting on hillsides after rain, use an iron rake to pull out small furrows, scatter the seeds, and then rake level; seedlings emerge in 6-7 days.
II. Sowing: Scutellaria baicalensis is sown in late autumn and in spring. Seeds sown in late autumn do not emerge that year and emerge in early spring the following year. Spring sowing is at about 18 degrees, with emergence in 6-10 days. Sowing method: open small furrows 1.5-2 cm deep at a row spacing of 20 cm, scatter the seeds, then rake level. If the surface is slightly dry, tread lightly once, then rake out the floating soil. Before sowing, the ground should be watered; after sowing, it should be kept moist. Seed treatment: 3 days before sowing, soak the seeds until swollen. After soaking in water for 8 hours, take them out, mix with sand, and keep moist. When a squeeze with the hand reveals sprouts and split cotyledons, they can be sown.
III. Field management: When seedlings are 8-10 cm tall, remove crowded seedlings and just open up the spacing. Pay attention to weeding during the seedling stage. Water timely when the soil is dry. If there is too much standing water in the field, drain it promptly. There are no pests or diseases.
IV. Harvesting and processing: After growing for 1 or 2 years, dig them out in late autumn or early spring and dry them in the sun to obtain the medicinal material.
