Planting techniques of Scutellaria baicalensis Georgi where is the origin of Scutellaria baicalensis Georgi

Astragalus membranaceus is a common traditional Chinese medicine, its shape is similar to the root, pick it up and smell it, there is a faint smell of traditional Chinese medicine. Astragalus membranaceus has many effects and is very popular in the market at present. So now many people want to grow it, so the first thing is to understand its planting technology.

Planting technique of Scutellaria baicalensis Georgi

First, planting Scutellaria baicalensis Georgi. Sowing can be divided into two ways: seed direct seeding and seedling transplanting.

1. Seed LVB:

Under the condition that the soil moisture is guaranteed during the sowing period of ①, it is appropriate to sow around the middle of April and the soil temperature of 5 cm is stable at 15 ℃, or to cover with plastic film from late March to early April, or to interplant between soybean and corn rows in early autumn.

Before sowing, ② seeds were soaked in 40-45 ℃ warm water for 5-6 hours or tap water at room temperature for 12-24 hours, removed and dried, moisturized and germinated at a temperature of about 20 ℃, and then sowed when some of the seeds sprouted.

③ sowing method: row spacing 40cm, depth 3cm 4cm, width 8cm 10cm shallow trench bottom flat, seed 1kg per mu, seed evenly spread into the ditch, then cover wet soil 2cm 2.5cm, and timely suppress and cover the ground, keep the soil moist until seedling emergence.

2. Seed seedling transplanting:

① sowed seeds in the first ten days of April, first poured enough water in the prepared border, and then sowed the treated seeds evenly in the border according to the sowing rate of 6g / m ~ 2.5g / m ~ 2, then covered with 0.5-1cm thick sifted dung soil or fertile topsoil, and then covered with film or broken grass to keep the border moist.

After the emergence of ② seedlings management, timely ventilation, film removal or cover grass should be removed, seedlings should be thinned according to the seedling spacing of 3-5 cm, weeds should be pulled out, and watering and topdressing should be appropriate according to specific conditions.

③ transplanting planting when the seedling height is 7cm and 10cm, trench planting is carried out according to the row spacing of 40cm and 10cm. After planting, the covering soil is compacted and watered at the right time, or it can be ditched and watered first, and then the seedlings are covered with soil after water infiltration. If there is no irrigation in dry land, it should be planted with rainfall.

Where is the origin of Scutellaria baicalensis?

The artificial cultivation areas of Scutellaria baicalensis are mainly produced in Shandong, Shaanxi, Shanxi and Gansu, among which they are concentrated in Nanfan Town, Jiangxian Town, Yuncheng County, Wanan Town, Wanrong County, Xuedian Town, Wenxi County, and other places. Shangluo, Qiaonan Town, Weinan Linwei District, Shangzhou District, Xiaoyi Town, Shangzhou District, Jingcun Town, Luonan County, Danfeng County, Dihua Town, Shangluo City, Night Village Town, Danfeng County Shandong Yimeng Mountain area, Ju County Kushan Township, Laiwu City Chayekou Town, Fuguanzhuang Township and other places. Gansu mainly produces Longxi, Weiyuan and Zhangxian, while Minxian, Dangchang and Hexi are the main producing areas.

Wild Scutellaria baicalensis Georgi is mainly distributed in most of the east-central and northeast provinces of Inner Mongolia, Chengde, Hebei, Chifeng, Inner Mongolia and other largest producing areas. It is distributed in Russia, East Siberia, Mongolia, Korea and Japan.

Field Management of Radix Astragali

In the emergence period, the soil should always be kept moist, the dry soil should be watered in time, the drought resistance of the adult plant should be enhanced, it can be watered less, and attention should be paid to drainage and waterlogging in the rainy season. At ordinary times, we should also pay attention to loosen the soil and weed at any time. In addition to strengthening general management, attention should also be paid to fertilization. In the first year, fertilization should be carried out for the first time after seedlings are fixed. 500 kg of human feces and urine or 5 kg of urea should be applied per mu, and 30 kg of ammonium phosphate should be applied from June to July. 50kg rotten cake fertilizer was applied after turning green in the second and third year, and 30ml / 40kg ammonium phosphate fertilizer was applied before ridge closure in late June. When applying fertilizer, it should be ditched, covered with soil and watered.

Harvest and processing of Radix Astragali

It is suitable to harvest 2-3 years after sowing Scutellaria baicalensis. Harvest season in late autumn or spring before sprouting, harvest should be carefully dug, do not dig off, dig out after shaking off the soil, sun to half dry, hit the outer skin, and then quickly dry or dry. At the same time to prevent rain and water washing. The method of hitting the skin of Scutellaria baicalensis Georgi is: hit your head when it is 30% dry, hit it twice when it is 50% dry, hit it third time when it is 70% dry, and bump it into yellow and white at noon for the fourth time when it is 100% dry. 150-200 kg of dry medicinal materials can be collected per mu.

At present, Astragalus membranaceus is still widely distributed in China, but there are only four main producing areas. When planting astragalus and purple, we need to understand its growth habits, and then do a good job of site selection, and finally plant. In the later stage, it is necessary to strengthen field management, so that the growth of Astragalus membranaceus will be good.
