Abstract: Taking the rose ‘Cherry Brandy’ as the experimental material and using greenhouse pot cultivation method, 8 treatments（root irrigation with clear water（CK1） and diluted carbon nanomaterials with 300-fold（TN1）,600-fold（TN2）,and 900-fold（TN3） were studied.The effects and comprehensive evaluation of foliar spraying with clean water（CK2） and diluted carbon nanomaterials at 300 times（YN1）,600 times（YN2）,and 900 times（YN3））on the growth and development of potted roses, in order to provide reference for the scientific and reasonable application of this material in roses.The results showed that reasonable application methods and appropriate concentrations of carbon nanomaterials could effectively promote the growth and development of potted roses.There were certain differences in the growth and development indicators of potted roses under different treatments, among which the average growth and development indicators of potted roses were the highest under irrigation root treatment and TN3 treatment; under foliar spraying treatment, the average growth and development indicators of potted roses under YN2 treatment were the highest.According to the comprehensive evaluation of the membership function, TN3 treatment was the most suitable formula for potted roses in this experiment.
