In this paper, Spray Seeding matrix retaining agent , chicken manure , peat soil , soil , straw , fertilizer available in accordance with the different amount and proportion orthogonal pot experiment and artificial rainfall erosion test , in order to the cinnamon soil Bunkyo study , test, the nine recipes in the pot experiment effect on the growth of tall fescue (Festuca arundinacea) and alfalfa (Medicago sativa) , and the study of the basic physical and chemical properties of each formula . Filter through integrated score and overall balance , the results obtained optimal formulation of tall fescue the group and alfalfa group were A1B2C3D3 and A3B3C3D3 that retaining agent 0.5g , chicken dosage 10.8g , peat soil proportion of the amount of soil, straw 40:40:20 , fast-acting fertilizer ratio of 3:1:3 and retaining agent to 1.5g , chicken dosage 16.2g , peat soil , the soil , the amount of straw ratio of 40:40 : 20 ??, available fertilizer ratio is 3:1:3 when the growth of tall fescue and alfalfa most favorable . And on the basis of the pot experiment the preferred out the recipe by adding a binder , anti - erosion properties of different slope , rainfall intensity and grass type conditions , by queuing scoring range analysis results obtained optimal formula A2B3C3D1, analog bare slope , adhesives dosage 0.4g , slope 45 °, rainfall intensity 213mm / h, grass seed type tall fescue minimal impact on the analog bare slope soil loss , erosion resistance best.
