The invention discloses a cutting propagation process of psammosilene. The process comprises the following steps: firstly carrying out re-cultivation on the tender stems of the psammosilene female parent; taking a pair of stems with axillary buds and leaves as a cutting propagation unit when the tender stems grow to 3-8cm and cutting all cutting slips; inserting the cut materials on a barbed wire in sequence to ensure that the stem parts at the lower ends of the cutting slips are soaked in culture solution; taking out the cutting slips when the soaked stems are expanded and inserting the cutting slips on a preconfigured and disinfected seedbed; timely removing the flower buds when lateral buds sprout and flower buds appear. The cutting propagation process of psammosilene is capable of remarkably accelerating the propagation speed of the psammosilene, shortening the seedling growing period, improving the germchit quality, providing technical guarantee for accelerating the germchit production of the psammosilene and bringing significance to the biodiversity protection.
