Growth habit

Atractylodes macrocephala likes cool climate, and is afraid of high temperature and high humidity environment. The requirements for soil are not strict, but weakly acidic, alkaline and light clay with good drainage and deep soil layer is better.

Plain areas should choose plots with loose soil and medium fertility. When the soil is over-fertilized, the seedlings grow too vigorously, which is easy to bolting and blossom in the same year, affecting the quality of medicinal materials. In mountainous areas, you can choose land with thick soil layer and certain slope for planting. It is better to use gramineous crops in the previous crop than tobacco, peanuts, rape and other crops, otherwise diseases will easily occur.
