The results showed that at the same fertilization level, all treatments of three kinds of anions increased chlorophyll content and stomatal resistance, decreased the net photosynthetic rate and transpiration rate of cucumber leaves;with the fertilization level increasing,the ratio of chla to chlb was increased i...
