摘要
在田间试验基础上,利用WinSRFR3.1模型模拟方法,开展了激光精细平地技术对内蒙古河套灌区畦田秋浇灌水质量影响和节水效果研究。结果表明,实施激光精细平地后,土地平整度达1.85cm,绝对改善程度为2.28cm,相对改善程度为55.2%,土地平整状况可得到大幅度改善。激光精细平地技术可使河套灌区秋浇灌水效率提高9.4%,灌水均匀度提高8.1%,深层渗漏减少17mm,节约水量9.7%,灌水质量提高明显,节水效果显著。
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.
