Flowering period It is long, has rich and colorful flowers, and has a large amount of flowers. It is a good plant material for flower beds, flower borders, and ground cover in the sun. It can also be viewed as a potted plant.

Scutellaria barbata is the dry above-ground part of Lamiaceae plant Barbata barbata. It has the functions of clearing heat and detoxifying, promoting blood circulation and removing blood stasis, reducing swelling and pain, and anti-cancer. Jiang Yi's "Yaojing Supplement" records that "half a lotus is a fairy grass that can relieve snake wounds." In addition to treating poisonous snake bites, folk medicine is also used to treat tumors, and it has certain short-term effects. "Corrected Compendium of Materia Medica" records that "this grass has purple-white flowers, purple-red grass, paired leaves, and is used in July and August." The morphology is similar to this species. There are many varieties of folk herbal medicine named Banzhilian or "Banzhi". "Baicao Mirror" records "there are seventy-two kinds of various half branches". Zhao Xuemin recorded in "Compendium of Materia Medica Supplements" that there are half-branch of rat tooth, half-branch of dog-tooth and half-branch of tiger-tooth, etc., which are several plants of the genus Sedum of the family Sedum. The half-branched lotus recorded in the 1985 edition of "The Pharmacopoeia of the People's Republic of China" is this product.

The leaves are opposite, triangular-ovate or oval-shaped, with wavy blunt teeth on the edges. The lower leaves are larger and the petioles are extremely short. The flowers are small, 2 opposite, arranged in lateral racemes, terminal; the pedicel is covered with sticky short hairs; the bracts are leaf-shaped, gradually becoming smaller upwards, and hairy. The calyx is bell-shaped, pubescent outside, bilabial, and the upper lip has a scutellum. Corolla lip-shaped, blue-purple, densely covered with pubescence outside; stamens 4, two strong; ovary 4-lobed, stigma fully inserted at the bottom of the ovary, 2-lobed at the top. Nutlets are oval, brown. The flowering period is from May to June, and the fruiting period is from June to August.

Ecological environment

Commonly found in wet places beside ditches, fields and roadsides. Soil that is too dry is not good for growth. Scutellaria barbata prefers a warm and humid climate and does not have high requirements for soil conditions.

Harvesting and Storage

Those propagated by seeds can be harvested once every year in May, July or September from the second year onwards. If propagated by divisions, the harvest can be done once in September of that year, and can be harvested three times a year thereafter. When harvesting, use a sickle to cut off the entire plant, remove weeds, bundle it into small handfuls, and dry it in the sun or shade.

Storage and care: Store in a dry place.

Nature, flavor and function

Pungent, bitter and cold. Returns to the lung, liver, and kidney meridians. Functions and Indications: Clearing away heat and detoxifying, removing blood stasis and diuresis. It is used for boils, swollen and painful throats, snake bites, pain from falls, edema, and jaundice. Usage and dosage: 15-30g, 30-60g of fresh product; appropriate amount of fresh product for external use, pound and apply to the affected area.

Planting technology

1. Land selection and land preparation

It is better to use loose and fertile sandy loam or loam, plow it, and apply it to farmers every acre. Use 2,000 kilograms of fertilizer as base fertilizer, plow finely and level it, and make a 1.3-meter-wide border.

2. Propagation method

Seed propagation is the main method, but division propagation can also be used. (1) Seed propagation is mostly carried out by direct seeding, from late September to early October, in drills or holes. For drill sowing, the row spacing is 25-30 cm, and the trench depth is about 4 cm; for hole sowing, the hole spacing is about 27 cm. When sowing, first spread the seeds into plant ash mixed with livestock manure water, mix it into seed ash, then spread it evenly into the ditch or hole, and cover it with a layer of fine soil or plant ash, the thickness shall not exceed 0.5 cm. After sowing, the soil should be kept absolutely moist before seedlings emerge. Seedlings can emerge about 20 days after sowing. Use 1.5-2 kilograms of seeds per acre. (2) Division propagation is carried out in spring and summer. Dig up the old roots of the plants, select strong, disease-free and pest-free plants for division. Each plant has 3-4 seedlings. Plant them in holes with a spacing of about 27 cm. Water after cutting.

3. Field management

(1) Thinning and replenishing seedlings. For live broadcast, when the seedlings are 5-7 cm high, the seedlings are thinned out at a spacing of 4-5 cm between plants, and seedlings are replenished at the same time. Transplant in soil and water after planting. (2) Cultivating and weeding should be carried out as soon as the seedlings emerge, and should be carried out in a timely manner after each harvest. (3) Top dressing combined with cultivating and weeding, with 2,000 kilograms of human and animal manure water applied per mu each time.

4. Prevention and control of diseases and insect pests

During the growth process of Scutellaria barbata, almost no diseases occur. During the flowering period, aphids and cabbage blackworms are prone to damage. The former can be controlled by dimethoate, and the latter can be controlled by dimethoate. 50% dichlorvos 1000 times liquid spray control.

5. Seed saving technology: From May to June, when the seeds gradually mature, harvest the fruit branches in batches, dry them in the sun or shade, rub out the seeds, dust off the stems and impurities, put them in cloth bags, and store them in a dry place Storage. There is no need to save seeds in the continuous cropping field of Barbata barbata. Generally, the root seedlings can be renewed once every 3-4 years.
