Irrigation and drainage of grass field using volcanic rock material

摘要

In order to obtain a four-season all-weather grass field, the present invention pans the ground of the existing stadium so as to form a drain plate whose bottom surface is slightly inclined toward the drain pipe. The parallel drainage pipe, the mesh and the drainage layer and the food material layer It is possible to control and balance the moisture and air of the medium on lawns planted with a volcanic ash, and it is possible to spray the sustained fertilizer to continuously supply nutrients to the lawn in the rainy season, It is the grass field which is made and it is done.
