Distributed in the northeast and north of mainland China, it grows at an altitude of 200 meters to 1500 meters above sea level, and is usually found in the undergrowth, forest edge, beside streams, thickets and valley meadows.
Dahurica dahurica is a perennial tall herb, 1 to 1.5 m. The root is long conical, the upper part is nearly square, the surface is gray-brown, there are most of the larger lenticel-like transverse protrusions, slightly arranged into a number of longitudinal rows, the texture is hard, heavier, the cross-section of the white, the powdery big. Stems and leaf sheaths are mostly yellowish green. The basal leaves are pinnately divided, long-petiolate, with tubular clasping, marginally membranous leaf sheaths in the lower part of the petiole.
The ultimate segments are oblong, ovate or linear-lanceolate, mostly sessile, 2.5 to 6 cm long, 1 to 2.5 cm wide, acute, with irregular white cartilaginous coarsely serrate margins, mucronate, and the basal two are often unequal in size, and decurrently winged along the leaf rachis; leaves below the inflorescences are simplified into unguillose, prominently inflated, saccate leaf sheaths, the outside of which is glabrous.
Compound umbels terminal or axillary, 10 to 30 cm in diameter, peduncles 5 to 20 cm long, peduncles, rays and petioles are hispidulous; rays 18 to 40.
Cultivation techniques:
One, the selection of the land to prepare the ground.
Dahurica dahurica is not very strict on the selection of the former, general cotton land, corn land can be cultivated, with deep tillage, loose and fertile soil, well-drained, warm and sunny relatively humid sandy soil, the general production areas are in the plains of the place for the better.
After the harvest of the previous crop, timely plowing depth of 33 cm is appropriate. After the sun and then turn again, and then rake fine leveling, for the border, 100 to 200 cm wide, 16 to 20 cm high raised beds, the border should be flat, the width of the border ditch 26 to 33 cm (poorly drained places with raised beds), the soil is fine and crumbly. Before plowing, apply about 150 kg of composted grass ash per hectare.
Two, propagation methods.
Propagation by seed, Angelica dahurica should be used in the year the seeds collected, the next year old seeds, germination rate is not high, or even do not germinate, can not be used. Some farmers experience with the main stem in the middle of the seeds, and then sowing, it is easy to pump early, affecting product quality.
Three, intercropping.
In order to economically utilize the land, in Angelica dahurica land can also be intercropped, in principle, short crops as well, after Angelica dahurica sowing, planting vegetables in its rows, such as bamboo shoots, spinach, garlic, etc., between the crops must be harvested in the spring, in order to facilitate the growth of white baffles, spinach, garlic is the most. Spinach is strip-seeded between the rows, and garlic seedlings are planted every 3 centimeters.
