The harvesting method of Angelica sinensis
Around the first ten days of October of the same year, the aboveground parts were cut off when the leaves were yellow, so that the sun came to the ground and the roots matured. Harvest in late October. When harvesting, dig out a section on one side of the field, and then use the two-tooth hook to dig out Angelica sinensis. Do not hurt the root and miss the plane when digging. It can produce 1500kg to 1700kg per hectare.

Field Management of Angelica sinensis
1. When the height of inter-seedling and fixed seedling is 3 cm, the first seedling is carried out, and then the second seedling is carried out half a month later. When the height of the seedling is 10 cm, fix the seedling. There were 2 or 3 strong seedlings in each hole. 2. Angelica sinensis grows slowly at the initial stage of seedling emergence, but weeds grow rapidly, so weeds should be weeded in time, from seedling emergence to ridge closure, weeding should be done for 3 or 4 times by stages. The first weeding was carried out when the seedling height was about 5 cm, the second time after the seedling was fixed, and the third time before the seedling height was 20-25 cm. Combine weeding to loosen the soil to prevent soil consolidation and modification.

Biological Characteristics of Angelica sinensis (Ⅰ)
Angelica sinensis seeds lose germination rate after one year at room temperature, and can be stored for more than 3 years at low temperature and dry condition. Mature seeds can germinate and grow under suitable conditions of moisture, temperature and oxygen. Seed germination has three processes: (1) Water absorption swelling process The components of Angelica sinensis seeds such as starch, fat, protein and cellulose are hydrocolloids, which are in gel state under dry conditions. When the seeds absorb water, water penetrates into the colloidal network structure inside the seeds and makes them gel.
