Effects of Laser Precision Land Leveling on Border Irrigation and Its Water Saving Performance
Abstract：The affect of laser precision land leveling on border irrigation performance and its water saving effect were analyzed with WinSRFR3.1 model based on field experiment.The results show that after implementation of laser land leveling,the field leveling precision indicator decreased to 1.85 cm and reduced by 2.28 cm or 55.2%,resulting in a great improvement on field surface condition.The results also show that laser precision land leveling can increase irrigation efficiency by 9.4%,uniformity by 8.1%,reduce deep percolation by 17 mm and save water by 9.7%,thus the increase of irrigation performance and water saving effect are highly significant.
