(一)方田建设的根由根据我省水资源短缺,供需矛盾突出,以及现有灌区水量浪费严重的实际情况。近几年来,我们在加强科学管理,推行计划用水的基础上,把工作重点放到斗渠以下的节水灌溉上。斗渠以下的节水工作面广量大,不仅潜力很大,而且直接关系到农业增产,是实现灌区农业生产稳定的基础。基于这种认识,宝鸡峡灌区从1981年开始,以探索建设节水、节能、省地、高产型新灌区,发展粮食生产基地建设为目的,选择了设施和经济效益差、群众浇地难、负担重、粮食产量低的东三支渠下游咸阳市秦都区北杜乡近万
(I) The Roots of Fangtian Construction According to the shortage of water resources in our province, the contradiction between supply and demand is outstanding, and the actual waste of water in the existing irrigation areas is serious. In recent years, on the basis of strengthening scientific management and implementing planned water use, we have focused our efforts on water-saving irrigation below the bucket quarry. Dugou following a wide range of water-saving work surface, not only has great potential, but also directly related to agricultural production is to achieve the stability of agricultural irrigation in the foundation. Based on this understanding, since 1981, Baojixia Irrigation District aims to explore the construction of new irrigation districts with water-saving, energy-saving, land-saving and high-yielding types and the development of grain production bases. It selects facilities with poor economic benefits, Heavy burden, low grain output of the East Third Branch canal Xianyu City, Qin Dudu nearly ten thousand
