Effect of planting density and harvesting date on yield and quality of <i>Artemisia argyi</i>.

ABSTRACT:

Background

Field investigations revealed that during the production of Artemisia argyi Lévl. et Vant. excessive planting density and untimely harvesting lead to desiccation and abscission of leaves in the middle and lower plant sections. The height of these withered leaves (dead leaf height) accounted for over 50% of the plant height, significantly reducing both the yield and quality of the medicinal herb A. argyi leaves.

Methods

This study employed field experiments using Nanyang A. argyi as the test material. Agronomic traits (including plant height, canopy width, number of effective leaves on the main stem, dead leaf height, stem diameter, internode length, and yield) and quality indicators (including volatile oil content, moxa yield rate, eucalyptol
