Scutellaria baicalensis Georgi is mainly distributed in several major production areas with the largest scale, such as central and eastern Inner Mongolia and most of the three northeastern provinces in China, Chengde, Hebei, and Chifeng, Inner Mongolia. It is one of the main production areas of wild Chinese medicinal materials in northern China.
Growth habit
Announce
edit
Root growth:Scutellaria baicalensis Georgi is a straight root. The main root grew normally in the first three years. The length, thickness, fresh weight and dry weight of the main root increased year by year. The content of baicalin in the main root is high.After the fourth year, the growth rate began to slow down, some of the main roots began to wither, and then increased year by year. Almost all the main roots and thicker lateral roots of eight year old family weight scutellaria baicalensis were withered, and the content of baicalin also decreased significantly.[2]
Stem and leaf growth:After emergence, the main stem gradually grows tall, the number of leaves gradually increases, and then forms branches, buds, flowers, and seeds.May to June is the long term of stem and leaf growth. The annual main stem of Scutellaria baicalensis can grow about 30 pairs of leaves, of which the first five pairs of leaves grow one pair every 4-6 days, and the subsequent leaves grow one pair every 2-3 days.[2]
blossom fruit:The annual plants generally begin to bud two months after emergence, and the biennial and later scutellaria baicalensis skullcap begin to bud more than 70 to 80 days after returning to green and emerging. The flowering begins about 10 days after bud emergence, and the fruit begins to mature about 40 days. If the environmental conditions are suitable, the flowering and fruiting of scutellaria baicalensis skullcap can continue to the frost and dry period.[2]
Growth environment
Born on sunny grass slope and fallow land, with an altitude of 60~1300 (1700~2000) meters.[1]
Scutellaria baicalensis is wild in dry places facing the sun, such as mountain tops, mountain slopes, forest edges, and roadsides.It likes warmth and is resistant to severe cold. The underground part of adult plants can survive the winter safely at - 35 ℃, and will not die at 35 ℃, but cannot withstand continuous high temperature weather above 40 ℃.Drought tolerance, fear of waterlogging, excessive water or rain in the ground, poor growth, and even root rotting death.The land with poor drainage should not be planted.The soil is loam and sandy loam, and the pH value is neutral and slightly alkaline, and continuous cropping is forbidden.[2]
Reproductive methods
Announce
edit
Euonymus japonicus is mainly propagated by seeds. It can also be propagated by branches or cuttings.[12]
Seed reproduction:
Live broadcast method
The seed propagation is mainly direct seeding. The direct seeding of Scutellaria baicalensis Georgi has a straight root system, few root forks, good product appearance and labor saving.The direct seeding is carried out more than in spring. Generally, the seeding is carried out when the ground temperature is stable at 12 ℃ - 15 ℃ 5 cm below the ground. In northern areas, it is mainly around the first half of April.[2]
Seedling raising and transplanting method
The seedling raising and transplanting method can save seeds, prolong the growth time, and ensure the whole seedling, but it is laborious. At the same time, the main root of transplanted Scutellaria baicalensis Georgi is short, there are many root forks, and the appearance quality of goods is poor. It is generally used when the seeds are expensive or it is difficult for direct seeding in dry land to emerge and maintain seedlings.[2]
Cutting propagation:Although cuttings can be propagated, they are seldom used in production.The key to the success of cutting is the cutting season and the cuttings.The survival rate of cutting is high from May to June in spring.The young part of semi lignified shoot tip should be selected for cuttings, and the survival rate of cuttings can reach more than 90%.[2]
Rooting propagation:That is, the 3-year-old rhizomes of Scutellaria baicalensis Georgi that have not germinated in the hole are dug, the main roots are cut for medicinal use, and then cut into several pieces according to the natural shape of the rhizome growth. Each piece can be planted with 2-3 bud eyes.[3]Although root splitting propagation grows fast, its propagation coefficient is too low and is rarely used in production.[2]
cultivation techniques
Announce
edit
Thinning and seeding
When direct seeding is adopted, when the seedlings grow to 4 cm high, dense and thin seedlings shall be interspersed, and the seedlings shall be fixed according to the plant spacing of 10 cm.Seedlings need not be thinned in the nursery.[2]
Intertillage weeding
After the seedlings are unearthed, the soil shall be loosened and weeded in time, and the soil shall be properly filled around the seedlings in combination with the loosening soil to keep loose and free of weeds. Weeding is required for 3-4 times a year.[2]
Fertilization irrigation
When the seedling height is 10-15cm, topdressing is once, and the application amount is 1500-2000kg of human and livestock manure water per mu.At the end of June to the beginning of July, 20 kg of superphosphate and 5 kg of urea were applied per mu. Ditching was conducted between rows and watering was conducted after soil covering.After the plants harvested in the next year wither, ditch between rows and apply 2000kg of decomposed manure, 20kg of superphosphate, 5kg of urea and 150kg of plant ash per mu, and then cover with soil.[2]
Scutellaria baicalensis is drought resistant and afraid of waterlogging. Pay attention to drainage in rainy season, and do not pond in the field, or the root will rot easily.In case of severe drought or after topdressing, water properly.[2]
Remove a bud
Before the inflorescence is pulled out, the pedicel is reduced to reduce the nutrient consumption, promote the root growth and increase the yield.[2]
Disease and insect control
Announce
edit
The disease includes leaf blight, which can be cleaned in the countryside. At the initial stage, spray 1:1:200 Bordeaux solution, or use 50% carbendazim 1000 times solution to control it.
Disease and insect control
Root rot, pay attention to drainage and implement rotation;The diseased plants shall be allocated and burned as soon as possible, and the soil at the diseased plants shall be sterilized with lime.
Insect pests include Scutellaria baicalensis Moth, which can be controlled by 90% trichlorfon.[3]

Folklore
Li Shizhen was born in the Jiajing period of the Ming Dynasty. He was smart and eager to learn from an early age.Shine the door.However, something unexpected happened. When Li Shizhen was ten or six years old, he suddenly suffered from an acute disease, coughed and could not recover for a long time.As his condition worsens, he spits more than a bowl every day, gets bored and thirsty, gets drunk, steams the bones and gets tired and hot, and the six channels flow. Although he takes bupleurum root, ophiopogon japonicum, schizonepeta tenuifolia, bamboo juice and other drugs to relieve exterior and fever, moisten the lungs and clear the heart, and clear away heat and phlegm, they have no effect.The famous doctors who lived a hundred miles around were helpless and thought they were beyond remedy.Xiaozhen's life is at stake.
When Li Shizhen's parents were sad and desperate, a Taoist came to the village from afar. The Taoist had white hair and long beard, which was quite like a fairy.Hearing that the Taoist priest specializes in curing difficult and miscellaneous diseases, Xiaozhen's parents hurriedly invited the Taoist priest to his home to see him.After giving her pulse, the Taoist stroked her long beard and said, "Well, well, just take 30g of Scutellaria baicalensis, add two cups of water, fry it to one cup, and take it for half a month to recover." Shizhen's parents were skeptical about the prescription. The miracle occurred. Half a month later, Xiaoshizhen's body heat completely subsided, his phlegm and cough disappeared, and his body gradually recovered.Scutellaria baicalensis has an immediate therapeutic effect.
Li Shizhen was deeply impressed by the magic of Chinese medicine and admired the Taoist with his unique skills. Since then, he has followed the Taoist to study medicine, read medical books through the ages, and traveled all over the mountains and rivers.Li Shizhen finally made great achievements in medicine and became a master of medical science.In his Compendium of Materia Medica, Li Shizhen highly praised the traditional Chinese medicine Huangqin, which had saved his life, and called it "a medicine that can cure the problem like a drum that responds to a beam, and a medicine that is wonderful."![6]
