Cultivation and Management of Angelica sinensis
The transplanted seedlings loosen the soil and weed for 3 times in one year, and the first time when the seedling height is 3~5cm. After weeding, topdressing was applied for the first time, 1500kg to 2500kg of sparse human and animal manure per 667m2, and 2500~3000kg for rotten stable manure, compost or fire soil ash per 667m2 for the second and third times. Bolting seedlings should be removed in time and watered during drought, but watering is prohibited in the later stage so as not to cause rotten roots. Early bolting: the key problem of Angelica sinensis in production is early bolting (in the year of transplantation). General early smoking

Management of Angelica sinensis in winter
Direct seeding angelica combined with topdressing before winter, manure soil covered on the seedlings or in the seedlings covered with about 1 cm of fine soil, so that it is free from freezing damage; seedling transplanting angelica winter to do a good job of seedling storage; seed angelica in order to improve seed yield and quality, before harvest must choose high mountains or semi-mountain ground growth robust, uniform seedlings. After that, the aboveground part of the remaining seed plants will be cut off, weeds will be removed, and they will be allowed to winter naturally, and they will be kept under constant supervision to prevent livestock from entering and trampling, resulting in lack of seedlings. Weeds grow in the following spring and can be pulled out by hand; the roots are covered with soil at this time

Seedling transplanting and direct seeding propagation of Angelica sinensis
1. Seedling transplanting (1) fresh seeds bearing fruit in the second year after transplanting should be selected for seed selection. Before and after the Beginning of Autumn, when the seed epidermis is blue or pink and the scape is drooping, cut off the scape together and put it in a ventilated and dry place to dry, threshing and storage. Avoid exposure, baking and rain. (2) sowing seedlings is usually sown with picking around the beginning of autumn, and it is suitable to sow seeds from mid-August to early September in low-altitude areas with slightly higher temperature. Timely sowing can avoid early bolting of Angelica sinensis. Too early, the seedling growth period is long.

Selection, preparation and transplanting of Angelica sinensis
(1) the land selection, land preparation and seedling cultivation should choose cool, fat and wet raw wasteland or mature land, and the loose and fertile sandy loam soil should be better, and the cultivation land should be fallow land or second wasteland with deep soil layer. In the middle of July, shrubs and weeds were cut down, spread on the ground and burned, then the land was turned more than 25 centimeters deep and matured in the sun, and then, before planting, 37500 kg of rotten barnyard manure per hectare was applied and turned into the soil as base fertilizer. Shallow ploughing once before sowing to make a high border 1.3 meters wide, with a width of 30 centimeters and a height of about 25 centimeters.

Artificial cultivation techniques of traditional Chinese Medicine Asarum
Asarum planted in Tieling area, called Liao Asarum, is a kind of traditional Chinese medicine native to Changbai Mountains. It mainly contains essential oil, asarone, palmitic acid, asarine, methyl eugenol and so on. The whole herb can be used as medicine. it is a good medicine for dispelling wind and cold and carrying water steam. it has the effects of analgesia, sedation, sweating, phlegm and so on. It is also used to extract insect repellents. The main results are as follows: (1) the life span of Asarum seeds is short, and the seeds germinated after sowing can take root quickly, but they will not be unearthed in the same year and will not emerge until the spring of the second year. The embryo of a naturally matured seed is not yet fully mature.

Medicinal Flowers: Asarum
1. Asarum heterotropoides Fr. Schm.var.mandchuricum(Ma-xim)Kitag. Alias tobacco bag pot flower, fine ginseng. Use the whole herb as medicine. Mainly produced in Jilin, Liaoning, Heilongjiang and other provinces. This medicine is the most important one among aromatic resuscitation drugs and is commonly used in clinical practice. However, the production area is too small and the output is not high, which cannot meet the market demand. 2. Plant characteristics perennial herbs. Rhizome transverse

How long is the life span of Asarum seeds?
The life span of Asarum seeds is very short, and the germination rate of naturally mature seeds is very high, up to 99%. However, after stored at room temperature and dry for 20 days, the germination rate decreased to 81% for 40 days, to 29% for 40 days, and only 2% for 60 days. As a result, it can be seen that the germination rate of Asarum seeds decreased gradually with the extension of storage period, and the dry storage period was only 60 days. As Asarum seeds can not be dried and stored indoors, they should be sowed or stored in sand immediately after harvest.

What are the main characteristics of Asarum cultivation?
The main characteristics of cultivation are long production cycle and strict technical requirements. Asarum is a perennial shady herb with a long production cycle. It takes 4-6 years from sowing to harvest. In the growth process of 4 ~ 6 years, in order to obtain higher yield, we must apply sufficient base fertilizer, timely topdressing, do a good job in the prevention and control of diseases, pests and rats, and do a good job in every work of field management. If a production link is negligent, it will bring certain losses to Asarum production. In order to increase the output value, it is necessary to save materials, use labor reasonably and refine in the whole growth cycle.

Sexual reproduction of Asarum
Both strip sowing and sowing are possible for sexual reproduction, and sowing is better. When the seeds were first collected, the germination rate reached 96%, dry for 20 days, 81% for 40 days, 29% for 60 days, and only 2% for 60 days. Therefore, after the seeds are ripe and harvested from June to July, they should be sown immediately. For some reason, the seeds could not be sown. After mixing 3 parts of wet sand and 1 part of seeds evenly, they were buried in the shade to maintain proper humidity, but the seeds could not be sowed later than the end of July at the latest, which would affect the long roots. About 5kg of fresh seeds are needed per mu. Seeding is often used to raise seedlings in the forest. Because of its loose soil

Asarum field management
Shading if there is no natural forest shading on the cultivated ground, remove the mulch before emergence, and then build a shading shed with a height of 80-100cm, covered with Artemisia grass, straw curtain or nylon net. Intertillage weeding 3-4 times a year. When ploughing
