PURPOSE: A vegetation concrete block is provided to plant trees. CONSTITUTION: When forming a concrete block, a filling rate is 25-40%, a void rate is 20-40% and the intensity of a general concrete block is maintained. A ratio of aggregates, cement, water and a water-reducing agent is respectively 80-85wt%, 12-13wt%, 2.5-3.5wt% and 0.1wt%. The size of the aggregate is 10-20mm. The block is separated from a mold by wet-curing for 48hours and dried naturally in air to prevent the reduction of the intensity. A filler to help plants is filled in the block or every vegetation method is applied on the surface of the block.
