The invention relates to a method for preparing a porous alumina composite material through a biological template method. The method comprises the following steps: duplicating a macro-pore tubular structure of a plant leaf, which is used as a biological template, through alumina in a material preparation process to obtain biomorphic alumina with a macro-pore fiber tubular structure; growing an LDHs (layered double hydroxides) nanosheet in a macro-pore channel of the biomorphic alumina in situ through an in-situ growth technology to obtain a porous LDHs / alumina composite material; roasting the porous LDHs / alumina composite material at the temperature of 500-800 DEG C to obtain the porous alumina composite material. The LDHs nanosheet is grown in the macro-pore channel of the biomorphic alumina, so that the specific surface area of the biomorphic alumina can be remarkably increased, and the pore structure of the biomorphic alumina is diversified. The porous alumina composite material can be widely applied to the fields of adsorption, catalysis and the like.

The invention relates to a soil improved composition and a method for improving soil, which belongs to the soil improvement field. The soil improved composition and the method for improving soil are provided for overcoming the shortages of uncontinuous greening effect on the slopes and high cost in the present greening technology. The soil improved composition comprises an organic matter, azotobacter flora, organism decomposed flora and acidic soil flora capable of promoting decomposition of rock, and enables good improvement of the soil, thereby the plant grown on the slopes can be deeply inserted in the rock, and the slope greening landscapes can be improved and the landslide can be prevented; the soil improvement method comprises the following steps: mixing the main soil and the soil improved composition, and planting herbaceous plants or woody plants in the mixed soil. The method of the invention can effectively improve the fertility of barren soil, and the soil improvement methodis suitable for popularization and application in the slope greening process.
