防止渠道渗漏,提高渠系有效利用系数,是新疆提高灌溉水利用率、防止土壤次生盐渍化的重要途径,也是保证农业稳产高产的一种根本性工作和实现农业“四化”的重要内容之一。目前,新疆已经进行了防渗的渠道,总长达2,600公里,其中灌区外部引水总干渠、干渠共约100条,长约1,900公里。 Preventing channel leakage and improving the effective utilization coefficient of canal system are important ways to increase irrigation water utilization rate and prevent secondary salinization of soil in Xinjiang. It is also a fundamental work to ensure stable and high-yield agriculture and realize “four modernizations” of agriculture. One of the important content. At present, Xinjiang has carried out anti-seepage channels with a total length of 2,600 kilometers. Among them, there are about 100 water main and diversion channels outside the irrigation area, about 1,900 kilometers in length.
