Lawn construction should strictly follow the established lawn design. <br>In lawn design, the location, scope, shape, water supply, drainage, grass species composition and trees planted on the lawn have all been determined. Lawn construction mainly includes terrain preparation, laying out fixed points, arranging water supply and drainage facilities, planting turf grass, and subsequent maintenance and management. (1) The purpose of <br>land leveling and plowing is to create conditions for root growth of lawn plants. The steps are: ① Remove debris.
