NOVELTY - Producing matrix material of lawn plantation comprises: (i) desalting using waste compost, removing the surface water by squeezing and air drying; (ii) deploying the matrix by adding calcium super phosphate, ferrous sulfate, urea and potassium sulfate in desalted and dried waste compost; (iii) preparing an adhesive by dissolving caustic soda in water, adding caustic soda solution in maize flour, adding hydrogen peroxide solution to a paste liquid; and (iv) pressing the matrix block by diluting the modified maize flour adhesive with water, and pressing the compost matrix.    USE - The method is useful for producing matrix material of lawn plantation.    ADVANTAGE - The method: is suitable for large-scale production; produces lawn planting and growing block for planting the lawn without using soil; is simple; and produces lawn planting, which has convenient transportation.    DETAILED DESCRIPTION - Producing matrix material of lawn plantation comprises: (i) desalting by using waste compost as a raw material, immersing the waste compost for 48 hours after mixing with water in a ratio of 1:2-1:3, removing the surface water by squeezing and air drying; (ii) deploying the matrix by adding (in g) calcium super phosphate (600-1000), ferrous sulfate (60-120), urea (80-125) and potassium sulfate (100-150) in the desalted and dried waste compost according to each m3 to obtain the compost matrix; (iii) preparing an adhesive by dissolving caustic soda in water at 50 degrees C to prepare caustic soda solution (1.7-2%), adding caustic soda solution in maize flour with a granularity of not less than 100 mesh, completely stirring to paste the maize flour to obtain a paste liquid, adding hydrogen peroxide solution (30%) in the paste liquid, where the volume ratio of hydrogen peroxide solution to the paste liquid is 1:50-1:60, uniformly mixing, maintaining the temperature for 1 hour at 50 degrees C to prepare the modified maize flour adhesive; and (iv) pressing the matrix block by diluting the modified maize flour adhesive with water to obtain the adhesive diluent, making the moisture content of the compost matrix after wetting to 55-65%, pressing the compost matrix after wetting as a matrix block, air drying, drying or roasting the matrix block to obtain the matrix material of lawn plantation with a moisture content of 30-40%. An INDEPENDENT CLAIM is also included for producing lawn planting and growing block, comprising performing steps (i), (ii), (iii), (iv) as mentioned above and (v) pressing the seed block by uniformly mixing Festuca arundinacea and annual bluegrass in a mass ratio of 4:1, grinding into 60 meshes according to 8-10 kg/m3 to uniformly mix with the matrix material, paving the mixture in a tray with a flat bottom into a thin sheet with a thickness of 5 mm, diluting the modified maize flour adhesive with clean water to 50 times of adhesive diluent, wetting the thin sheet on the tray with the flat bottom by the adhesive diluent to a moisture content of 55-65%, pressing the wet thin sheet into the seed block with a thickness of 3 mm, drying the seed block with the tray with the flat bottom in a blast dryer at 35-40 degrees C to obtain the seed block with a moisture content lower than 15%, and overlapping the seed blocks on the matrix block prepared in step (iv).
