The invention discloses a garden greening planting construction process. The process is characterized by comprising the following operation steps that a spiral drill rod is used for forming tubular pits in a planting area through drilling, and in the rotating process of the spiral drill rod, two collecting cylinders are arranged on both sides of the spiral drill rod and spliced, and a cylindricalchannel is formed between the two collecting cylinders; the spiral drill rod is positioned in the channel, and the section size of the spiral drill rod is matched with that of the channel, so that thespiral drill rod rotates spirally, and soil can be spirally taken out; soil then falls into a collecting barrel from an opening in the upper portion of the collecting barrel, surface soil is locatedat the bottom of the collecting barrel, and bottom soil is located on the top of the collecting barrel; after drilling operation is completed by the spiral drill rod, the collecting barrel and the spiral drill rod are removed. In the planting process, the spiral drill rod is used for forming the pits through drilling, so that the operation efficiency is improved; in a pit drilling process, the drilled surface soil firstly enters the collecting cylinders, correspondingly the surface soil can fall into the bottoms of the pits, deep soil can fall into the upper layers of the pits, and manual soilseparation is not required, so that the operation efficiency is improved, and the soil planting condition is improved.
