Standardized cultivation techniques of Angelica sinensis
1 Land selection and land preparation 1.1 Land selection. Select the sandy loam with deep, loose, good drainage, fertile and rich in organic matter. To raise seedlings, it is best to choose the north gentle slope of half-shade and half-yang, and it is appropriate to transplant in the place of leeward to the sun, avoiding continuous cropping. 1.2 ground preparation. The cultivation land should choose the field with deep soil layer, turn deeply 2 or 3 times before sowing, turn the soil more than 25 cm deep, speed up the soil ripening through the sun, and then combine with soil preparation before planting, apply mature farm manure 23.3 tons / mu, compound fertilizer 30kg / mu, turn into the soil to make the foundation.

Prevention and control of root rot of Angelica sinensis
Angelica root rot, also known as root rot disease, is one of the main diseases in the growth and development period of Angelica sinensis, which has a great impact on its yield and quality. The main results are as follows: 1. harmful symptoms: harmful to roots and stems. The root tissue of the diseased plant was brown at first, and then rotted into water immersion, leaving only a fibrous shell. The stem is brown and watery, the growth of the aboveground part stops, and the plant is short. Oval brown patches appeared on the leaves, and in severe cases, the leaves withered and sagged, even the whole plant died. 2. Pathogenic bacteria: (Fusariumavenaceum (

Angelica sinensis is covered with sunshade net to increase production, quality and benefit.
The shading cultivation technique of Angelica sinensis starts from the three-leaf stage of Angelica sinensis (that is, from mid-May to early August, when high temperature and strong light after summer), and covers the shading net with a shading rate of 50%. It provides a suitable small environment for Angelica sinensis production to grow under the original ecological conditions of medium temperature, weak light and humidity. by cooling, humidifying and reducing light, the bolting rate of Angelica sinensis in dryland cultivation can be reduced to about 30%. Moreover, the sunshade cultivation of Angelica sinensis can prevent and reduce the harm of diseases and insect pests, so it can improve the quality of Angelica sinensis.

Storage of Angelica sinensis
Angelica contains volatile oil and rich sugar, it is very easy to go oil and absorb moisture, the temperature is too high during storage, too long time or long-term contact with the air, the oil content is easy to seep out, resulting in oil stains on the surface of medicinal materials, causing deterioration, corruption and oil; excessive humidity or high water content of the medicine itself is prone to insect pests and mildew, so dried Angelica should be stored in a dry, cool place, and do a good job of disinfection. The stored Angelica sinensis should be clean and dry, the water content is less than 13%, and there is no mildew or moth. Use double

Cultivation techniques of Angelica sinensis
Angelica sinensis is propagated by transplanting with seeds. The harvest in the second year of autumn direct seeding or the harvest of spring direct seeding in the same year were also found in lower altitude areas (1500-1800 m), but the yield and quality were low. Choose cool and moist Yinshan or Eryin Mountain, potholes and small basins that conserve water but do not accumulate water, instead of dry wind beams. Soil quality requires loose and fertile, there is no stone large black soil or black oil sand, generally choose wasteland to raise seedlings. Make a high border 1 meter wide on the leveled plot and plant it in mid-late June while it is wet.
