Scutellaria barbata is the dry ground part of the Lamiaceae scutellrla barbata. It is also known as occlusive grass, rushing mountain whip, and toothbrush grass. With heat detoxification, blood stasis, swelling and pain relief, anti-cancer and other functions. Distributed in various provinces and regions in southern China. (A) Morphological characteristics of perennial herbs, plant height 30 cm to 40 cm. The roots of the lower part of the stem grow upright. Stems are square and green. Leaves opposite, leaf blade triangular-ovate or ovoid, undulate-edged margins, lower leaves larger, petiole extremely short. Flowers small, two opposite, arranged in lateral racemes, terminal; pedicel shortly villous; bracts leaflike, gradually turning upward, hairless. Calyx campanulate, villous outside, 2-lipped, upper lip with scutellum. Corolla lip-shaped, blue-purple, densely pilose outside; stamens 4, 2 strong; ovary 4-lobed, stigma fully inserted at base of ovary, apically 2-lobed. Nutlets oval, tan. Flowering from May to June, fruiting period from June to August. (ii) Growing habits Scutellaria barbatus prefers a warm and humid climate, and it requires less soil conditions. Wild more common in the ditch, the edge of the field and the wet roadside. Too dry soil is unfavorable for growth. The seeds are easy to germinate, and the germination temperature is 25 c. Seed life is 1 year. (III) Cultivation Techniques 1. It is better to choose land and soil preparation for loose, fertile sandy loam or soil, plowing, and apply 3000 kg of farmyard fertilizer per 1,000 square meters as basal fertilizer, plowing and leveling to make a 1.3-meter-wide plutonium. 2. Breeding methods are mainly based on seed propagation, and they can also be propagated on the ramets. (1) Seed breeding: Many live broadcasts, from late September to early October, on-cast or hole sowing. Drilling is carried out by 25 cm to 30 cm of row spacing, and the depth of the ditch is about 4 cm. Holecasting is based on the opening of a hole about 27 cm away from the hole. When sowing, the seeds are first scattered into the ash mixed with livestock manure water, and mixed into seed ash, and then evenly scattered into the ditch or hole, covered with a layer of fine soil or plant ash, about 20 days after sowing can be raised. Seed 500 grams to 600 grams per 1,000 square meters. (2) Breeding: In spring and summer. The old roots of the plants were excavated, and the strong, disease-free pest plants were selected for ramification. Each plant had 3 to 4 shoots, and the hole was planted at a distance of about 27 cm from the hole and watered after planting. 3. Field management (1) seedlings, make-up seedlings: Live seedling height 5 cm to 7 cm when the spacing between 4 cm to 5 cm for the seedlings, while the make-up seedlings, make-up seedlings should be transplanted with soil, watering after planting. (2) Cultivating and weeding: When the seedlings emerge, they will be cultivated and weeded, and they should be carried out in time after each harvest. (3) Top-dressing: Combining cultivating and weeding, top-dressing 2 000 kg to 3 000 kg of livestock and manure water per 1000 m2. After 3 to 4 years of cultivation of Scutellaria barbata, the senescence of plants and the weakening of germination ability must be carried out by cultivating another plant or reseeding. 4. Diseases and insect pest control Scutellaria barbata in the growth process, almost no disease occurred, flowering period susceptible to aphids and vegetable black insect damage, the former can be used dimethoate control, which can be used 50% of dichlorvos 1000 times spray control. (4) For the seeds that are harvested and used for processing, they can be harvested once every year in May, July and September from the second year. If the plants are divided, they will be harvested once in September of that year and then harvested three times each year. At the time of harvest, the whole plant shall be cut with a trowel, and the weeds shall be removed and bundled into small pieces, dried or dried. (V) Seed-keeping techniques From May to June, when the seeds mature gradually, the fruit branches will be harvested in batches, sun dried or dried, the seeds will be picked up, the stems and impurities will be removed, placed in cloth bags and stored in a dry place.
