Experience in cultivation and Management of Scutellaria baicalensis Georgi

I. use and postpartum benefits of Scutellaria baicalensis Georgi

Scutellaria baicalensis Georgi is the root of perennial plant of Labiatae, which has the effect of clearing heat and dryness, purging fire and detoxification, stopping bleeding and calming fetus. It is often used for dampness and temperature, summer temperature, chest tightness, vomiting, damp-heat spleen fullness, diarrhea, jaundice, lung heat cough, high fever, exasperation and thirst, hematemesis, carbuncle, sore poison, fetal movement and other symptoms. No matter in clinic or in the materials of proprietary Chinese medicine, the dosage of this product is increasing year by year, especially in recent years, the extract of Scutellaria baicalensis Georgi is not only in great demand at home, but also more popular in the world. Most of the Scutellaria baicalensis produced in 2006 was acquired by the refinery as the raw material of the extract in the fresh stage, so this year the drug market will rely on the old goods before 2006 to maintain its supply, the supply is less than 50% of the normal year, and its price will rise day by day with digestion. by the time it is born this year, it is reasonable that its price will rise by 2030% at the current price of 8 yuan per kilogram. According to the general yield per mu 200kg, the unit price is calculated at 10 yuan, the benefit per mu can reach more than 2000 yuan. It is much higher than the benefit of growing grain. Therefore, planting Scutellaria baicalensis Georgi this year is the best year for drug farmers to make a profit.

Areas and soils suitable for cultivation of Scutellaria baicalensis Georgi

Scutellaria baicalensis Georgi is resistant to drought and cold, and its roots can withstand a low temperature of minus 30 ℃, but it likes temperature, is afraid of waterlogging and stagnant water, so it is only suitable for planting in the area north of the Yellow River. The soil is highly selective to soil, and the most suitable soil for its growth is the fertile sandy land, which is easy to lose water, but is not afraid of drought. As long as it is watered and fertilized at the right time, its root system will develop quickly and greatly, and the yield will be high. Although viscosity can also grow, but the yield is low. Every living creature has its own specific living environment and growth habits, which is determined by the inherent genetic conditions of the organism. Therefore, we must also follow this principle in the cultivation of medicinal materials, otherwise we will not be able to achieve the goal of high yield.

III. Key points of cultivation techniques

1. To select good plots and land preparation, we should first select fertile and easily drained sandy land according to the above requirements, and then apply sufficient bottom fertilizer, in which farmers' high-quality ring manure should be 2500, 3000 kg per mu, 500 kg of plant ash, 50 kg of superphosphate, and then turn the land 2535 cm deep, then rake the land fine and level it into a 1.5-meter-wide border.

2. Sowing the seeds of Scutellaria baicalensis Georgi at the right time is about 1 kg per mu. The spring sowing time should be completed by mid-April. Before sowing, the seeds of Scutellaria baicalensis Georgi with a germination rate of more than 80% should be soaked in warm water for a week, and the seeds can be sown if they are slightly dry. When sowing, the seeds should be evenly sprinkled into the border, covered with slightly pressed soil, and watered immediately after sowing. When the local temperature reaches 16 ℃ and 17 cm, the seeds can emerge in half a month.

IV. Field management

1. Fixing seedlings and filling gaps when all seedlings are unearthed to 5 cm, seedlings should be thinned, overdense and weak seedlings should be removed, seedlings can be fixed when the height of seedlings reaches 10 cm, plant spacing should be 10 cm, and seedlings can be taken and transplanted to remedy the lack of seedlings in order to keep the whole seedling strong.

2. with the continuous growth and growth of Scutellaria baicalensis Georgi, weeds also grow. Therefore, weeding must be ploughed, which is not only conducive to the growth and development of Scutellaria baicalensis, but also prevent weeds from competing with Scutellaria baicalensis.

3. Topdressing in time when the height of the seedling reaches 15 cm, 25 kg of compound fertilizer and 5 kg of urea should be applied per mu, and 20 kg of superphosphate should be applied from June to July, and when Scutellaria baicalensis Georgi blossoms for the third time, finally, 0.5 kg of potassium dihydrogen phosphate per mu is applied to the leaf surface of Scutellaria baicalensis Georgi, which can be sprayed three times in sunny days.

4. the main enemy of Scutellaria baicalensis Georgi in pest control is leaf blight. Once this disease occurs and spreads quickly, it leads to rapid death of leaves. Especially in the high temperature and rainy season, the incidence is high. The disease is characterized by irregular dark brown spots that spread from the tip or edge of the leaf to the center of the leaf. As soon as the disease is found, 1000 times of carbendazim should be sprayed three times in a row, once every 7 days. In addition, the Scutellaria baicalensis moth encroaches on the leaves of Scutellaria baicalensis, and the harm is also very serious. Once the application of 9% trichlorfon 1000 times liquid spray treatment. If root rot occurs again, the diseased plant should be pulled out in time, burned outside the field, and disinfected with lime at the same time, and then irrigated the disease area with 50% carbendazim 500 times solution, in order to achieve the purpose of complete sterilization.

V. harvesting and processing

The mining time of Scutellaria baicalensis should be when the stems and leaves are withered and yellow after autumn, and it can also be dug in the same year, but the yield is low and the content of baicalin is low. The baicalin content of Scutellaria baicalensis after three years is higher than that of wild Scutellaria baicalensis. After digging, the soil stems and leaves should be removed. Due to the new characteristics of market purchase and sale, fresh products can be listed on the market, so drug farmers sell them while they are fresh in order to save trouble.
