Afforestation structure suitable for stony desertification area

The utility model relates to the technical field of afforestation, in particular to an afforestation structure and an afforestation method suitable for rocky desertification areas. Drought-enduring sapling selection, the roots of the seedlings are wrapped with seedling soil balls; planting holes are dug in the positions, with the thickness larger than 20 cm, of the soil layer; the volume width ofthe planting hole is twice that of a seedling soil ball; the depth of each planting hole is 20 cm; a dicranopteris pedata humus lower layer is laid at the bottom of the planting hole; a water-retaining agent and a compound fertilizer are uniformly scattered on the surface of the dicranopteris pedata humus lower layer; nursery stock soil balls are placed on the surface of the dicranopteris pedata humus lower layer; wherein the surface of the dicranopteris pedata humus lower layer is filled with a dicranopteris pedata humus upper layer, the height of the dicranopteris pedata humus upper layer ishalf of the height of a s
