The planting cost of Angelica sinensis includes seedling, plastic film, chemical fertilizer, pesticide and artificial management. An acre of land needs about 6-8 kilograms of seeds, and the cost per kilogram is about 120 yuan and 720-960 yuan. Adding plastic film and chemical fertilizer to 300 yuan/mu, the labor management cost is 1.500 yuan/mu, and the total input cost is 2520-2760 yuan/mu.
An acre of land produces an average of 450kg of fresh angelica, and after drying, it produces an average of dry angelica 100kg. According to the current market situation, the average price of Angelica sinensis is 40 yuan/kg, and the income per mu is 4,000 yuan. Excluding the cost, the income per mu varies from 1480- 1240 yuan.

Second, the favorable conditions for planting Angelica sinensis
1, height
Angelica sinensis is suitable for growing at high altitude. Low altitude will affect the output and poor quality.
2. Temperature
Angelica sinensis is sensitive to temperature, and the optimum growth temperature is between 20 and 24 degrees. Maintaining this temperature range at seedling stage can make it emerge quickly.
3. Land
Angelica likes fertile and loose humus soil with good drainage, which can provide nutrients for the growth of Angelica sinensis.
4. Lighting equipment
Angelica sinensis is a light-loving plant, which grows fast and strongly in an environment with sufficient sunlight, and it is also easy to bolting (chüutáI). Insufficient light will affect the yield of angelica sinensis. Therefore, choosing sunny slope and properly adjusting planting density are beneficial to root growth.
Third, planting techniques and management of Angelica sinensis
1, land selection and land preparation
Choose a gentle slope from south to north, semi-cloudy and semi-sunny, which requires loose soil and good structure. Before Xiaoman, it was a deep turn 1 time, and the clods were broken to make seedbeds. The width of the bed is 1 m, and the length varies with the terrain. The drainage ditch between beds is 30cm wide and 15-20cm deep. The planting area should be deeply plowed and raked, and the base fertilizer should be 2500-5000 kg per mu, and the soil should be ploughed evenly to make the border high and wide, 1.2- 1.5 m. The gutter between beds is 30cm wide and 20cm deep.
2. Breeding mode
Seedling raising and transplanting are often used in production. The sowing date should be determined according to the altitude and temperature in different places, such as around July in Gansu, Sichuan and Yunnan, and around August in Shaanxi. The sowing method is sowing. The seeds of Angelica sinensis are mixed with ash and scattered on the border, slightly suppressed, covered with a small amount of fine wet soil and covered with grass, and the seedling age is no more than 1 10 days. The sowing amount per mu is 4-5 kg. Transplanting is divided into winter planting and spring planting, and the plant spacing is 25cm×25cm. Spring seeds should be planted around Tomb-Sweeping Day, and winter seeds should be transplanted after cold dew and before the first frost. Direct seeding can be used in winter, spring and autumn, which can control the early bolting of angelica sinensis. Direct seeding in winter is better, but the yield is not high.
3. Cultivation management
① Seedling management: The soil must be kept moist after sowing to facilitate seed germination. About 40 days, pick the straw loose. When the seedling height is about 3 cm, loosen the soil 1 time, and immediately pull out the weeds. After the cloudy day, pull out all the covered grass. Pay attention to drought prevention and drainage at seedling stage.
② Seedling storage: when the temperature drops to about 5℃ in the first frost, when the seedlings begin to wither, dig up the seedlings, tie them into sticks with a little soil, dry them in the sun to remove water, and store them in the cellar. If the seedlings are too old, they are not suitable for storage. When storing, pay attention to the head facing outward and the root facing inward.
(3) Replanting and interplanting: In general, after all the seedlings are planted about 20 days after transplanting, replanting is carried out, and seedlings with soil are replanted in rainy days. Seedlings are fixed about 3 months after planting, and the weak seedlings are pulled out, leaving 1 plant in each hole.
④ intertillage weeding: in mid-May, weeding was done for the first time, shallow hoeing was carried out, and seedlings were not buried. In mid-June, the second weeding can be done deeply to promote root development.
⑤ Bolting: After transplanting, the plants that blossom and bear fruit in that year are called early bolting, and the roots are not used as medicine, so it is advisable to pull them all out.
⑥ Topdressing: Angelica sinensis is a fertilizer-loving plant, and phosphorus, potassium and ammonia fertilizers should be topdressed in the Ye Sheng period in late June and the root growth period in early August.
4, pest control
The common diseases and pests of Angelica sinensis include mouth disease, Sclerotinia sclerotiorum, needle worm, black cutworm adult and so on. It can be controlled by routine spraying of pesticides.
