美刊《土木工程》1978年第一期报道利用激光控制平整农田,可以提高地面灌溉效率。新近在平整土地过程中利用激光。因它不仅能提高平整土地的准确性,而且也减少了对操作人员的依赖。在平整农田时利用激光控制设备,地面高低差最多为25～30毫米。 US publication “Civil Engineering” 1978 the first report using laser control of farmland, can improve the efficiency of surface irrigation. Recently used lasers in the formation of land. Because it can not only improve the accuracy of the formation of land, but also reduce the dependence on the operator. In the formation of farmland using laser control equipment, the ground level up to 25-30 mm difference.
