我省井灌区,近年来地下水提取量增加,补给量减少,许多地区潜水位迅速下降,以深层地下水为水源的灌区,因补给条件差,地下水位下降更为严重,灌溉水的供需矛盾日趋尖锐。因此,研究节水灌溉技术,提高灌溉水的有效利用率,对保护和合理利用水资源具有紧迫的现实意义。广大群众在实践中,创造了多种形式的行之有效的
In the well irrigation area of our province, in recent years, the extraction of groundwater has been increased and the supply has been reduced. The diving potential in many areas has been rapidly declining. Irrigation areas that use deep groundwater as their source of water have worsened due to poor supply conditions and the water table has become more and more contradictory. . Therefore, studying the technology of water-saving irrigation and improving the effective utilization of irrigation water are of urgent practical significance for the protection and rational utilization of water resources. In practice, the broad masses of the people have created various forms of effective ones
