ABSTRACT
Arsenic stress inhibited the growth of Panax notogensing. The citric acid and phosphorusfertilizer can promote the growth of notogensing, increase the biomass and morphological index, improve the efficacy of saponins and flavonoid contents. They also make it release of soil arsenic, increasing arsenic content in Panax notogensing to exceed the standard, phosphorus is not conducive to the release of arsenic in soil, reducing the absorption of arsenic in plants.
