The invention discloses a sightseeing greenhouse succulents improvement matrix and its preparation method. The matrix is prepared from the following raw materials, by weight, 30-50 parts of a light material, 40-60 parts of an organic matter, 4-8 parts of an inorganic fertilizer, 5-10 parts of bentonite, 0.5-1.5 parts of a microelement fertilizer and 0.5-1.5 parts of a plant protectant. The light material is one of components selected from vermiculite, perlite, ceramsite and volcanic or an arbitrary combination of two of the components. The organic matter is one of components selected from soybean cake, rape seed cake, cottonseed cake, leaf mould and bone meal or an arbitrary combination of two of the components. The inorganic fertilizer is obtained by mixing ammonium thiosulfate, monopotassium phosphate, potassium nitrate, ammonium phosphate and potassium sulphate. The microelement fertilizer is obtained by mixing ferrous sulphate, ammonium molybdate, manganese sulfate, zinc sulfate and copper sulphate. The plant protectant is obtained by mixing alpha-naphthylacetic sodium salt, diethyl aminoethyl hexanoateDA-6, 70 wt% of thiophanate-methyl and hymexazol. By the use of the improvement matrix, soil can be improved, fertilizers can be saved, the environment can be protected, and rooting speed of succulents can be raised.
