这样一来，土壤疏松，渗水、通气良好，有利于草坪植物的根系发育，也便于播

In this way, the soil is loose, has good water penetration and aeration, which is conducive to the root development of lawn plants and is also convenient for sowing or planting grass. <br>③ Drainage and irrigation systems <br>are the same as other venues. The drainage of lawn surface water needs to be taken into consideration. <br>Therefore, when finally leveling the ground, ground drainage must be taken into consideration. <br>There should be no depressions there to avoid water accumulation. <br>Lawn drainage is mainly achieved by using gentle slopes. Build a gently sloping trench within a certain area. A rainwater outlet can be set up at the lowest end to receive discharged surface water and drain it away through underground drainage pipes.

In this way, the soil is loose, permeable, and well ventilated, which is conducive to the root development of lawn plants and also facilitates sowing or planting grass.<br>③ Drainage and irrigation system<br>Like other venues, the drainage of lawn surface water needs to be taken into account.<br>Therefore, when finally leveling the ground, ground drainage should be taken into account.<br>There should be no low spots there to avoid water accumulation.<br>Lawn drainage is mainly achieved through gentle slopes. Build a gentle slope ditch within a certain area, and the lowest end can be equipped with a rainwater inlet to receive the discharged surface water, which is then discharged through underground drainage pipes.

In this way, the soil is loose, water seepage and ventilation are good, which is beneficial to the root system development of lawn plants and is also convenient for sowing or planting grass.<br> ③ Drainage and irrigation system<br> Like other sites, the drainage of lawn ground water needs to be taken into account.<br> Therefore, when the ground is finally leveled, the ground drainage should be taken into account.<br> There should be no depressions there to avoid water accumulation.<br> Lawn drainage is mainly achieved by gentle slope.
