    摘要:

    随着我国农业生产的发展,特别是灌溉农业的发展,盟渍土壤的改良和利用,将成为农业生产中一项重要的工作。

    Abstract:

    The roles of the natural development and some properties of the soils in this area are briefly discussed as follows: The soils are saline and calcareous in nature, in which over 70% of the total soluble salts are sodium chloride. Slight to moderate alkalinization may be developed, while the total soluble salt contents exceed 0.2%;but generally, there is no NaCO3 present. The ground water table in this area is usally high, and the quantity and constituents of the salts in ground water are directly varied with and influenced by that contained in the above soils. The saline and alkali properties of soils in this area are originated from the parent materials, through the action of the sea water when they were deposited. As soon as the sea water ceased to affect, the soils as well as the ground water are gradurally desalinized by natural leaching and this process will be strengthened by the biological activities. As the desalinization of the soils is proceeded further, the ratio of Na+/Ca+++Mg++ in the soil solution decreased and the amount of the exchangeable Na on the soil colloidal complex is finally lowered. It is evident that desalinization also introduces the dealkalinization of the soils in this area; there is no hazard of strong alkalinization of the soils taken place through leaching.
