Artemisia annua L. is suitable to grow in the environment of loose soil, fertile soil and good drainage, so it is a good choice to choose sandy loam as far as possible, such as riverside and grassland. After selecting the land, it is necessary to deeply dig the soil 25cm, and apply about 1750 kilograms of mature farm manure per mu, then flatten it, and dig a ditch for later drainage and irrigation.

4. Management technology in the later stage of transplanting: how to manage it?

The main results are as follows: (1) Seedling replenishment: after Artemisia annua seedlings are planted for a week, the growth of seedlings should be checked in time, weak and withered seedlings should be pulled out in time, and dense seedlings should be transplanted into sparse loam soil in time to ensure uniform growth of seedlings.

(2) Intertillage weeding: after successful intercropping, weeding should be done in time to prevent nutrients from being absorbed and to ensure good soil permeability. Do not hurt the roots when loosening the soil. for those with more weeds, they can be pulled out manually.

(3) requirement of water and fertilizer: when loosening the soil, base fertilizer can be properly applied to ensure sufficient nutrients of the plant. When fertilizing, do not apply thick fertilizer, so as not to burn the roots.
