Abstract
Selenium (Se) is a kind of important trace elements in organisms, and selenium deficiency or excess will lead to human disease, therefore, it is of great significance to study the application of selenium fertilizer. In this study, through using pot experiment with selenium rich soil collected from Xiqing District of Tianjin, the effects of foliar spraying selenium fertilizer on the physiological characteristics of pakchoi were studied under different fertilization treatments. The results showed that the application of organic fertilizer and compound fertilizer can increase the net photosynthetic rate, transpiration rate and stomatal conductance of pakchoi leaves, and two times spraying Se can increase photosynthetic characteristics of pakchoi, while under the treatment without spraying Se, the intercellular CO2 concentration of pakchoi leaves was higher. Under the application of organic fertilizer, the activity of SOD and CAT was increased by two times spraying Se, while, the POD activity was increased by foliar spraying Se under the application of compound fertilizer
