To safeguard the quality consistency and traceability of Panax notoginseng, while streamlining fertilization practices and enhancing cultivation efficiency, a field plot fertilizer substitution trial was executed. Employing traditional fertilization as the control（CK）, three distinct experimental treatments were crafted utilizing ammonium polyphosphate water-soluble fertilizer （SRF）： Alternative fertilization （T1）, reduced fertilization （T2）, and formula fertilization （T3）. The results showed that under SRF treatment, there were no significant differences in agronomic traits, nitrogen （N）, phosphorus （P）, potassium （K） nutrients, soil organic matter （SOM）, cation exchange capacity （CEC） and other soil physical and chemical properties of Panax Notoginseng compared with CK. Compared with CK, T3 did not change the species diversity and richness of soil bacteria, and did not affect the species richness of soil fungi, but T3 increased the species diversity of soil fungi. Compared with conventional fertilization, ammonium polyphosphate water-soluble fertilizer could not only achieve cost saving and efficiency improvement for the cultivation of Panax notoginseng, but also reduce the harm of fertilization to the soil environment by improving the structure of soil flora, soit could be widely applied.
