Application And Comparison Of Subsurface Drip Irrigation On Turf Under Different Lateral Plans

In order to apply the subsurface drip irrigation (SDI) technology on turf, this study based on the traditional subsurface drip irrigation,decorated grid shape. Through the research of uniformity of linear, grid,tian glyph subsurface drip irrigation; the soil water movement of single water dropper and grid water droppers;the practice application of subsurface drip irrigation on turf; the evaluation of cost to the sprinkler, linear layout and grid layout on football irrigation system,showed that the subsurface drip irrigation grid can reach 90% uniformity, higher than linear subsurface drip irrigation; under the condition of single water dropper, the soil moisture content changed dramaticly in horizontal distance from 0 to 15 cm,soil moisture can reach 15 cm distance in 45 minutes, reach 20 cm distance in 60 minutes, reach 30 cm distance in 90 minutes,there were two peak soil moisture content at the time of 30 minutes and 90 minutes under the grid side 30cm,The grid side 30cm subsurface drip irrigation of adjacent soil water had overlapping effect at the time of 90 minutes;Subsurface drip can satisfy the turf's normal growth and golf course requirements, had the remarkable water-saving effect, convenient management,saved labor;Drops for 30cm,pipe spacing for 40cm, depth for 15cm was a recommendatory design combination; The unit area material cost of standard football stadium in irrigation system were sprinkler irrigation 8.07 yuan,linear layout 10.46 yuan,netty layout 15.30 yuan, but water cost and energy consumption was far more than subsurface drip irrigation.The application of subsurface drip irrigation on turf will have a good prospect.
