摘　　要：马蹄金的光饱和点约为１１４３μｍｏｌ／（ｍ２·ｓ），光补偿点约为４３μｍｏｌ／（ｍ２·ｓ），对强光有较强的适应性。ＣＯ２补偿点约为８０×１０－６，确定其为Ｃ３植物。ＡＬ合剂处理后，使马蹄金功能叶片的光合速率增加，光合产物输出速率加快。The photosynthetic charactristics of Dichondra repens was studied. It was found that the light saturation point of Dichondra repens was 1 143 μmol/(m 2·s), and light compensation point was 43 μmol/(m 2·s) approximately. The experimental results indicated that Dichondra repen was adaptable to intense light and suitable for growth in the region of the middle and down reaches of the Yangzi River.Morever, it was shown that AL reagents(contain photorespiratory inhibitor NaHSO 3, etc.)increased photosynthetic rate and dry matter accumulation.
