Continuous cropping obstacle drastically inhibits the plant growth, medicinal composition and tuber productivity of Pinellia ternata and restricts its industry development. The physiological and electrophysiological responses of P. ternata under continuous cropping over 2 years are few systematic reports, and its obstacle monitoring method remains undeveloped. Based on the results, continuous cropping 1~4 years obviously could inhibit the morphological development, emergence rate, photosynthesis, antioxidant enzyme activities, medicinal composition of P. ternata and enhanced its sprout tumble rate and resistance-related substance contents, as well as declined 23.84%~59.20% of tuber yield. Meanwhile, continuous cropping could dramatically inhibit its intracellular water metabolism, nutrient transport, metabolic activity, and intrinsic capacitance (IC) and increase its intrinsic resistance (IR), impedance (IZ), inductive reactance (IXL), and capacitive reactance (IXc). Additionally, these inhibiting or promoting effects heightened with increasing duration of continuous cropping. Reliably, the comprehensive growth index (CGI) and continuous cropping obstacle index (CCOI) based on plant's electrical information exhibited good correlations with the physiological and electrophysiological parameters, which accurately and rapidly characterized the growth and continuous cropping obstacle status of P. ternata. This study systematic described the physiological and electrophysiological characteristics of P. ternata to perennially continuous cropping, and developed a novel monitoring approach based on plant's electrical information, as well as provided new insights for monitoring and mitigating its continuous cropping obstacle.
