Marcotting, also known as high-density layering or air layering, is a plant propagation technique. It involves making ring cuts or incisions in the bark of a branch, then wrapping it with a moist medium (such as sphagnum moss or Jiffy Peat Pellet) to create an airtight layer, promoting root growth at that location. The rooted branch is then cut off to become a new plant. This method is commonly used for propagating woody plants and prized flowers, and is particularly suitable for tree species with stiff, inflexible branches.
空中压条法又称高压法或高枝压条，是一种植物繁殖技术，通过在枝条上环状剥皮或刻伤，然后用湿润的介质（如水苔、吉惠泥炭饼）包裹并形成气密层，促进枝条在该部位生根，最终将带根的枝条剪下成为新植株。此方法常用于繁殖木本植物和名贵花卉，尤其适用于枝条硬不易弯曲的树种。
