1 机井规划机井规划应根据水文地质条件,地下水资源状况,地形、提水机械和作物布局等情况结合起来考虑,机井布置应与地下水流向垂直或接近垂直,适应当地水文地质条件。机井建设是农田基本建设的一个重要组成部分,因此,机井规划不能孤立地进行,要在示范区水利建设总体规划的基础上,根据水文地质条件,结合灌、排、路、林、电及渠道、机耕等统一考虑,达到便于灌溉和耕作。2 井灌工程效率评价的基本公式
1 well planning Well planning should be based on the hydrogeological conditions, groundwater resources, topography, water lifting machinery and crop layout considerations combined, well layout and groundwater flow should be vertical or nearly vertical, to adapt to the local hydrogeological conditions. Construction of well is an important part of farmland construction. Therefore, the planning of well can not be carried out in isolation. Based on the overall planning of water conservancy construction in the demonstration area, according to the hydrogeological conditions, combined with irrigation, drainage, road, forest, electricity and channels , Plowing and other unified consideration, to facilitate irrigation and farming. 2 well irrigation project efficiency evaluation of the basic formula
