治理方针的正确与否关系到盐碱土改良的成功与失败、高效与低效,是非常重要的。摸清盐碱土的成因,然后进行改良,才能收到预期的效果。土壤盐碱化的发生与发展,是在本地区内自然因素包括气候、地质、地形、植被、水文地质等的长期综合作用下土壤中水盐运动的结果,在耕作地区还受人为活动的影响。土壤中可溶于水的盐分,常随水的运动而运动。大地的盐分来源于岩石风化,它在随水运动过程中,使土壤母质和地下水中都含有一定盐分;海潮的浸渍,也能把盐分带到陆地。当地下水位超过临界深度,尤其是在强烈的蒸发作用下,盐分随水 The correctness of the management policy is related to the success and failure of the improvement of saline-alkali soil, efficient and inefficient, it is very important. Find out the causes of saline soil, and then make improvements to receive the desired results. The occurrence and development of soil salinization are the result of the movement of water and salt in the soil under the long-term comprehensive effects of natural factors such as climate, geology, topography, vegetation and hydrogeology in the region and are also affected by human activities in farming areas . Soil water soluble salt, often with the movement of water movement. The earth’s salt comes from rock weathered, which contains some salt in the soil parent material and groundwater during its movement with the sea. Impregnation of the tide can also bring salt to the surface. The local water table exceeds the critical depth, especially under intense evaporation, with salt water
