The invention discloses a turfgrass nematode control method which comprises the following steps: (1) preparation of turfgrass cultivation matrix: 5-15 cm deep fertile soil is evenly mixed, and is divided into two parts, wherein one part is used as inoculation soil, and the other part is disinfection soil which is implemented dry heat sterilization for two hours at the temperature of 160 DEG C; inactivated garbage composts and waste rubber particles with 0.5-1 mm particle size are additionally taken; the following raw materials are taken and are mixed evenly in parts by weight: 90-160 parts of inoculation soil, 140-260 parts of disinfection soil, 90-460 parts of garbage composts and 10-20 parts of waste rubber particles; (2) sowing of turfgrass; and (3) management and maintenance of turfgrass. The method can reduce soil compactness, bring convenience for movement of water in the soil, and modify water retaining property of the soil; and the garbage composts have an obvious restraining effect on plant parasitic groups, and can effectively kill and restrain breeding and growth of nematodes.
