摘要
盐碱土因含有过量的盐分、有毒物质、碱度过大及不良的土壤物理性状 ,对植物生长产生抑制作用 ,导致区域生态恶化。本文对巴盟河套灌区盐碱地的形成、演变规律及历年治理的经验进行了分析 ,对盐碱地治理、利用的最佳途径进行了探讨。盐碱地治理利用的途径有很多 ,生物与工程措施并举是盐碱地治理利用的最佳途径 ,它可以控制盐碱地的发生、发展并使地形平坦、土层深厚、适于机耕、具有潜在肥力的大面积的盐碱地变成良田和森林 ,达到盐碱地的最佳利用途径 。
Being contained oversalt, poisonous substance, high alkalinity and bad physical behavior of soil, salinealkali soil can restrain plant growth and lead to regional ecological deterioration. In this paper, analysis has been done on formation of salinealkali land, transmutation rhythm and management experience over the years. The optimum way to manage and utilize salinealkali land has been discussed. It is the best way to combine biology with engineering measures.It can control outbreak and development of salinealkali land.It also can make a large area of salinealkali land which have smooth topography, deep soil layer, potential fertility turn into good farmland and forest in order to bring their economic and ecological effect into play.
