| 摘 要： | 以受污染果园的龙眼为试材,研究了土壤Pb和Cd含量的变化及其对龙眼叶片光合特性的影响。结果表明:土壤中Pb和Cd的含量都与果园高度呈负相关,地势越高处含量越低;PAR在500～1500μmol/(m2.s)范围内,各种光合特性参数均随着Pb和Cd含量的增加而减小。

| Abstract: | The distribution characters of lead(Pb) and cadmium(Cd) in polluted longan orchard and their effects on the physiological characteristics of longan were studied.The results showed that both Pb content and Cd content had negative correlation with the height of orchard,the higher the land was,the less the Pb and Cd content in it was.When PAR-value was in the range of 500 ～ 1500 μmol/(m2.s),all photosynthetic characteristic indexes decreased along with the increasing of Pb and Cd content. |
