The excessive rainfall and irrigation amount in the facility herbal medicine production system (FHmPS) China leading to a severe root rot disease of Panax notoginseng, which endangers yield quality, compromise economic profit waste resources. Therefore, objective our research was seek optimal cultivation management strategy for FHmPS improve notoginseng benefit. A three-year (2019, 2020 2021) field experiment conducted on under two shelter-cultivation [rain-shelter (Sr) unrain-shelter (NSr)] at three deficit levels [I1= 65%W, I2= 75%W, I3= 85% W, where W quota when upper lower limits are (100% ∼ 40%)θFC shelter-cultivation] explore combined practices effects yield, benefit, water productivity (WP) nutrients uptake obtain supply practice by technique order preference similarity ideal solution (TOPSIS). results showed that SrI2 obtained relatively high plant nutrient uptake, net profit, WP, quality. significantly decreased incidence 6–17.5% comparison other treatments. However, compared with rain-shelter cultivation, weaken these notoginseng. Deficit promoted Sr higher WP than NSr. According result TOPSIS, comprehensive ranking SrI3 were first second among practices, regardless growing seasons planting years. 5.4%− 20.8% highly recommended semi-arid area Southwest China.
