Poor drainage conditions, resulting in soil water, planting of root rot, recommended additional catch basins and drainage in catchment lowest, increase the efficiency of surface drainage
Poor drainage conditions, resulting in soil water accumulation, plant roots decay, it is recommended to add yin wells and drainage pipes at the lowest point of the collection of water to increase surface drainage efficiency
The drainage condition is not good, which leads to soil water accumulation and root rot of planting. It is suggested to add a manhole and drain pipe at the lowest part of the water collection to increase the surface drainage efficiency<br>
