A method for planting trees on cut slopes and banked slopes by compaction of green soil and a green soil composition used to the method are provided to improve the porosity and water/nutrient retaining properties of a vegetation base material, and to strengthen the durability against rainfall and dryness by compacting the vegetation base material with high pressure air. A green soil composition used to a method for planting trees on cut slopes and banked slopes by compaction of green soil comprises 45~55vol% of activated compost, 30~40vol% of bark compost, 5~10vol% of charcoal, 5~10vol% of vermiculite, and 5~10vol% of oyster shell. The green soil composition is made by the steps of: crushing waste wood into needle-shaped chips having a length of 20~30mm and a width of 5~10mm with a crusher; mixing chicken feces, a nitrogenous fertilizer and fermentation fungus, and firstly fermenting the mixture in a piling step to obtain activated compost; mixing bark compost with the activated compost, and secondly fermenting the mixture to obtain organic compost; and mixing charcoal, vermiculite and oyster shell to the organic compost. A method for planting trees on cut slopes and banked slopes by compaction of green soil comprises the steps of: installing an adhesion-enhancing structure(10) for enhancing the adhesive strength of green soil(3) on a tree-planting area(1); and adhering the green soil to the adhesion-enhancing structure through a nozzle with compressed air by using a wet mortar plant. The green soil is compacted at a level of 2000L per square meters, wherein 2000L of the green soil is mixed with 4kg of a controlled-release fertilizer, 1.0kg of Lunasol powder and seeds. The adhering process is performed at one time regardless of the adhesion thickness of the green soil. |
