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, plan carefully and manage carefully during the whole growth cycle.

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.

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
