The invention belongs to the technical field of agricultural planting and particularly discloses a passion fruit cuttage seedling cultivation method. The method includes steps: (1) seedling cultivation container preparation, to be more specific, adding a prepared medium into a conical frustum shaped plastic container to obtain a seedling cultivation container, wherein the medium is prepared from turf, pumice, fine sand, medical stone, corncobs, cow dung, humic acid, amino acids, ground phosphate rock, mixed bacteria and additive extract according to certain parts by weight, and the additive extract is prepared from rheum officinale, algae, oxalis corniculata, phytolacca acinosa, litchi rind, semen persicae and semen pharbitidis; (2) cutting branch preparation; (3) cuttage; (4) seedling cultivation management including temperature and humidity management and nutrition management. The cuttage seedling cultivation method is scientific in management, adopted nutrient sources completely meet passion fruit seedling cultivation requirements, high cutting branch rooting rate and high seedling emergence rate are realized, and passion fruit seedlings cultivated according to the method is robust in growth, high in disease resistance and high in transplanting survival rate.
