土地盐碱化是造成土壤退化、土地资源短缺和生态环境恶化的主要原因之一。
在容易发生盐碱化和渍害的地区，应当采取措施，控制和降低地下水的水位。
植物能够减少土壤表层积盐，并可以降低碱化度；苜蓿地比玉米地具有更低的钠吸附比值。
1·Using five kinds of different alkalized conditions in the experiment, the result showed that alkalization by strong ammonia was the best condition and obtained the highest rate of alkaloids.
在实验中采用五种不同的磁化条件，结果证明以浓氨水进行碱化为最佳条件，生物减收率最高。
2·As natural cellulose linter pulp raw materials, HEC is the name of a series of products after alkalization and etherification.
纤维素醚是以天然纤维素(棉桨粕或木桨粕)为基本原料，经过碱化、醚化反应而生成的一系列产品的总称。
3·At last we got coarse alkaloids after concentration. Then we refined it through acid dissolution alkalization and extraction by organic solvent.
然后采用酸溶、碱化、有机溶剂萃取的方法对所得粗品进行了精制。
4·Vegetation could mitigate salt amount in earth surface, and reduce the degree of soil alkalization.
植物能够减少土壤表层积盐，并可以降低碱化度；苜蓿地比玉米地具有更低的钠吸附比值。
