摘　　要：为引导学生通过考察校园中三种常见观赏绿植-花叶鹅掌柴、月季花及大叶黄杨对土壤中水溶性钙、镁、铁三种元素的吸收情况,找到为三种植物个性化合理施肥的科学依据,团队设计了创新型实验,选用EDTA络合滴定法及分光光度法对三种植物所在地块的钙、镁、铁元素含量进行分析。研究结果对于土壤中水溶性元素测定及三种植物的培育有一定的参考价值,并培养了学生独立思考及解决实际问题的能力。An innovative experiment was designed to investigate the uptake of water-soluble calcium,magnesium and iron by three common ornamental green plants on campus,namely,Schefflera actinopylla“Variegata”,Chinese rose,and Buxus megistophylla Levl,in order to provide a scientific basis for individualized and rational fertilization of the three plants.The results of the study were useful for the determination of water-soluble elements in the soil and the cultivation of the three plants,and developing students abilities to think independently and solve practical problems.

关 键 词：创新实验 络合滴定 分光光度法 元素含量测定
