In recent years, in our province, Wugang, Baofeng, Ye County, Pixian and other places continue to expand the area, the increasingly serious harm. From 2005 to 2007, we observed and studied the biological characteristics of Artemisia annua, aiming to provide a scientific basis for the prevention and control of Artemisia annua. 1 sowing Artemisia biological characteristics broadcast Artemisia is a Cruciferae, 1-year-old or older herbs.
