一、从渠道防渗谈起 新疆是一个内陆干旱地区,地多水少,水土不平衡,没有水就不能种地。在开垦初期,我们就进行了大量的水利建设,由于当时条件所限,没有采取防渗措施,渠道渗漏很严重,大量补给了地下水,抬高了地下水位。在强烈的蒸发作用下,加速了土壤次生盐渍化过程。经验告诉我们,只修水利工程,不注意解决土壤次生盐渍化问题,不但达不到高产稳产的目的,反而会使大面积耕地由于次生盐渍化而弃耕。 First, from the canal seepage Xinjiang is an inland arid areas, with less water, water and soil imbalance, no water can not be planted. In the early stage of reclamation, we conducted a lot of water conservancy projects. Due to the limited conditions at that time, we did not take any measures to prevent seepage. The seepage of the channels was very serious, a large amount of groundwater was replenished and groundwater levels were raised. In the strong evaporation, accelerated soil secondary salinization process. Experience tells us that only water conservancy projects, do not pay attention to solve the problem of secondary soil salinization, not only fail to achieve high yield and stability of the purpose, but will make large areas of cultivated land due to secondary salinization and abandoned.
