1, temperature, the suitable temperature range of Artemisia selengensis is very wide. In early spring, when the temperature rises to about 5℃, the lateral buds (latent buds) on underground stems begin to germinate. The average daily temperature is 12 ~ 18℃, and the stems are easy to lignify when the average daily temperature is above 20℃. The aboveground parts will die in heavy frost, and the roots and roots of the underground parts can overwinter in the open air. Wild Artemisia argyi in the open field usually germinates in spring, and its vegetative growth accelerates in early and middle May, which is the peak of its growth. If protected cultivation is adopted, the listing period can be advanced to the middle and late period of 65438+ February last year. If the temperature is suitable, Artemisia selengensis can grow all year round without obvious dormancy period.

2, light, Artemisia is a long-day crop, like a sunny growth environment, but the tender stems are easy to age under strong light. The flower bud differentiated in early July, bolting began in late July, flowering in the middle and late September, and bearing fruit in 65438+ 10.

3. Humidity. Artemisia argyi has shallow roots and likes humidity. Both dry land and shallow water can grow. 60% ~ 80% soil moisture is the most favorable for the growth of rhizomes and the emergence of tender stems. The field with poor drainage has few roots and poor growth. After long-term waterlogging, the roots turn brown and die. It is not easy to die under the conditions of high temperature and drought in summer, but the plant growth is poor.

4, soil fertilizer, Artemisia selengensis is not strict with the soil, but it is suitable for loose and fertile sandy loam with rich organic matter and good drainage, and does not grow well in sticky and barren soil. Artemisia selengensis is fertilizer-tolerant, and the requirement for nutrients is mainly organic fertilizer, which requires a large amount of fertilizer. Proper application of nitrogen fertilizer and more phosphorus and potassium fertilizer is beneficial to improve quality and yield.
