降低地下水位是促进农作物正常生长与防治盐碱化的重要措施。从农作物的正常生长来看,要有适宜的水分、阳光、温度、空气、肥料等基本条件,地下水位比较高不利于农作物的生长;从防治次生土壤盐碱化来看,必须降低地下水位到地下水临界深度以下。因此在治涝中不仅需要及时排除地面涝水,还要及时降低地下水位。 Reducing groundwater level is an important measure to promote the normal growth of crops and prevent and control salinization. From the normal crop growth point of view, there should be adequate water, sunlight, temperature, air, fertilizer and other basic conditions, higher groundwater table is not conducive to the growth of crops; from the control of secondary soil salinization point of view, we must reduce the water table To below the critical depth of groundwater. Therefore, it is not only necessary to timely remove surface waterlogging in flood control, but also to reduce groundwater level in time.
