【Abstract】 Ponkan of fifteen years old was used as material in the experiment. The effect of spraying zinc on leave to content of chlorophyll,protein, soluble car bohydrate and rate of photosythesis was studied. The results showed that: Spray ing zinc on leaves was able to enhance the content of chlorophyll?soluble carboh ydrate and protein and to enhance photosynthetic net rate that was enhanced with spraying times.更多还原
