摘要
负水头毛细渗灌非常适合青海湖周边沙漠地区的固沙植生,根据毛细渗灌原理对节水器进行设计,考虑植物的需水量,棉线毛细输水量,沙子的输水特性可确定节水器的输水量及入渗点。
Water infiltration under water supply of negative hydraulic heads is suited to irrigation in the deserts around Qinghai lake. According to water infiltration principle, one kind of water economizer is designed. Considering the water consumption of the plant, the water delivery of cotton, property of water capillary conductivity in sand, water conductivity magnitude and the position where water infiltration will begin from the water economizer are designed.
