摘 要: | 对盐渍化人工草地土壤盐分离子(Cl-、SO2-4、CO2-3、HCO-3、Na+、K+、Mg2+、Ca2+)及土壤有机质、全氮、全磷等营养成分在0~30cm土层内的动态变化规律进行了连续分析测定。为进一步客观评价“生物治碱”功效提供了可靠依据。

Abstract: | To the salt ions (including Cl~-、SO_4~(2-)、CO_3~(2-)、HCO_3~-、Na~+、K~+、Mg~2+、Ca~2+) and Soil organic substances, total nitrogen, total phosphorus and all such nutrient contents-all those dynamically changing laws governing the soil layer from 0 to 30cm, were analyzed and determined continuously. For further objective evaluation, the effect of ‘brought under control biologically’ were then offered for our reference on the basis of reliable information. |
