Continuous cropping alters rhizosphere microbial communities and soil properties reducing Curcuma Kwangsiensis yield.

ABSTRACT: Curcuma kwangsiensis is a medicinal plant endemic to China with significant economic and medicinal value. In agricultural practice, it is typically harvested after one year of cultivation. However, continuous cropping has severely constrained the development of the C. kwangsiensis industry. To elucidate the effects of continuous cropping on the yield and rhizosphere soil environment, this study systematically investigated the effects of continuous cropping on C. kwangsiensis yield, rhizosphere soil physicochemical properties, enzyme activities, and microbial communities through field experiments. The results showed that continuous cropping significantly reduced C. kwangsiensis yield by 58.87%. It decreased soil pH while increasing the accumulation of soil nutrients including organic carbon
