摘　　要：在猪场厌氧废水和清水中分别种养3种饲料植物(空心菜、水稻、水葫芦),研究不同水环境对不同植物净光合速率、气孔导度和叶绿素等相关生理指标的影响。结果表明:饲料植物在污水中的光合速率、气孔导度和叶绿素均比清水中的高。不同的饲料植物、水质对光合速率、气孔导度和叶绿素含量影响差异显著,而且它们对光合速率和叶绿素含量存在交互作用。By means of potting fodder plants （lpomoea aquatica Forsk, Oryza sativa,Eichhornia crassipes ） in sewage and water, changes of net photosynthetic rate, stomatal conductance and chlorophyll were researched. The results indicated that the value with net photosynthetic rate, stomatal conductance and chlorophyll of fodder plants potted in sewage were larger than those in water.Influence of the value with net photosynthetic rate, stomatal conductance and chlorophyll had obvious difference and content of net photosynthetic rate and chlorophyll existed interaction under different fodder plants and aquatic environment.
