摘　　要：本文以修武县杨树黄叶病为对象,研究了其光合蒸腾作用,结果表明:健康的杨树的光合作用、蒸腾速率和气孔导度均最高,其次是喷施FeSO4的杨树黄叶病株,未处理的病树3种指标最低,说明喷施FeSO4能显著提高杨树病株光合作用、蒸腾速率和气孔导度。The article studied on on the Photosynthesis, Transpiration rate. and stomatal conductance of Yellow Leaf Virus Populus. The results showed that three indexes of healthy Populus were higher FeSO4 treated Yellow Leaf Virus Populus. All indexes of Yellow Leaf Virus Populus were the lowest. This indicated that FeSO4 promoted three indexes observably.
