ion uptake of plant 植物离子吸收
Plant uptake of a metal depends primarily on the free metal ion activity.
植物对金属的吸收主要取决于自由态离子活度。
High concentration of salt in soil causes ion imbalance, oxidative damage, water deficit and nutrient deficiency, which lead to molecular damage, growth retarded, and even death of plant.
土壤中高浓度的盐分会使离子失衡、氧化伤害、水分亏缺、营养缺乏，并导致生物大分子被破坏、生长迟缓、甚至植株死亡。
Compared with the old process or ion exchange process, the improved process shows clear advantage and is suitable to be used in a fertilizer plant having carbon dioxide and ammonia resources.
新工艺与原工艺及离子交换法工艺相比较均有较明显的优势，适合于有二氧化碳和氨资源的化肥厂采用。
