金县农场有两条长6,050米的支渠,过去由于渗漏严重,每年损失水量多达37～42万方,占全年总用水量的14%以上.渗漏造成土壤盐渍化,使渠道两侧近百亩地颗粒无收.后来,采用混凝土预制板衬砌渠道4,032米,每年节约的水量可灌400亩农田,渠道旁不产生盐渍化,工程造价比当地浆砌石衬砌渠道低30%以上. There are two 6,050-meter branch channels in Jinxian Farm. In the past, due to serious seepage, the annual loss of water volume was as high as 37-420,000 square meters, accounting for more than 14% of the total annual water consumption.
