NOVELTY - Method for constructing ground from landfills with dredged soil, involves digging the dredged soil from a reclaimed ground surface layer into the predetermined depth, spreading a drainage layer material chosen from gravels, wood chips, or a first soil improver on the dug up space to form a drainage layer, preparing a vegetating soil composition by mixing the dredged soil with a second soil improver, installing the composition on the drainage layer to form a vegetation layer, planting trees on the vegetation layer, and sowing seeds on the vegetation layer for fixing the surface of the ground.    USE - The method is useful for constructing ground for planting tree. The tree is chosen from Pinus thunbergii, Celtis sinensis, Chionanthus retusus, Ulmus davidiana and Quercus myrsinifolia (claimed).    ADVANTAGE - The method is environmentally-friendly, reduces stabilization period of plant and has excellent profitability and practicability.    DETAILED DESCRIPTION - Method for constructing ground from landfills with dredged soil, involves digging the dredged soil from a reclaimed ground surface layer into the predetermined depth, spreading a drainage layer material chosen from gravels, wood chips, or a first soil improver on the dug up space to form a drainage layer, preparing a vegetating soil composition by mixing the dredged soil with a second soil improver, installing the composition on the drainage layer to form a vegetation layer, planting trees on the vegetation layer, spraying compounds chosen from calcium phosphate, phosphoric acid ammonium, ammonium sulfate, potassium nitrate, calcium cyanide, ammonium nitrate, potassium sulfate and manganese sulfate to layer and sowing seeds on the vegetation layer for fixing the surface of the ground, where vegetating soil composition comprises (in wt.%) (a) 65-85 wt.% of calcium compounds and magnesium compounds in the ratio of 3-5:1, 1-6 wt.% of iron compounds and aluminum compounds in the ratio of 6-8:1, (b) fermented organic matter (55-80), nitrogen compound (3-18), phosphorus compound (3-25), sulfur compound (0.3-0.5), molybdenum compound (0.5-1), boron compounds (1-3), zinc compound (0.5-0.8), manganese compounds (0.5-1), copper compounds (0.3-0.8) and chlorine compound (0.3-0.5) and (c) Anabaena, Anabaenopsis, Dactylococcopsis, Synechocystis and Microcystis.
