This invention relates to cinnamomum micranthum breeding forestation on low-altitude level ground. In the invention, a cinnamomum micranthum branch which belongs to the same species as cinnamomum micranthum is grafted onto a matrix base of a level-ground cinnamomum camphora, such that a nutrient source for growing a cinnamomum micranthum plant is established by grafting the cinnamomum micranthum branch onto the matrix base exposed on the ground. With the level ground cinnamomum camphora tree itself which is suitable for growth in level-ground condition and climate and possessed with roots of excellent water absorption and drainage to facilitate water absorption and photosynthesis of the cinnamomum micranthum branch, the cinnamomum micranthum branch can vigorously sustain to grow into cinnamomum kanehirai hayata. In addition, a hewing spot is preset on a grown trunk and branches of the cinnamomum kanehirai hayata, such that after being hewn, a proper section of the cinnamomum kanehirai hayata is reserved on the matrix base of the cinnamomum camphora to lastingly grow into a new individual cinnamomum kanehirai hayata, thereby transplanting the cinnamomum micranthum at low altitude to achieve the purpose of level-ground breeding forestation.
