Prepared yellow soil substrate，mixed substrate of coconut bran and yellow soil，mixed substrate of coconut bran and sandy soil，and coconut bran substrate，and compared the rooting number and rooting time of the cuttings on those media. The results showed that the mixed substrate of coconut bran and sandy soil was most suitable for Olea europaea cuttings，on which，callus appeared in 24 days，rooted in 70 days，and the rooting rate was 87.80%. The results of this study can contribute to improving the efficiency of Olea europaea cuttage breeding，assisting the development of woody oil，and realizing the benefits of ecological civilization.
