Abstract
Effects of different types of acid rain(Sulphuric Acid Rain,Nitric Acid Rain and Mixed Acid Rain) of different pH values on pakchoi plant height,fresh weight of aerial part,dry weight of aerial part,chlorophyll,soluble sugar and vitamin C were studied in the experiment.The results show that as the pH of acid rain reducing,there are decline of pakchoi plant height,fresh weight of aerial part and dry weight of aerial part in different degrees.When the pH value is 5.6,the pakchoi growth indicators reach the highest.And the impact of nitric acid rain on pakchoi growth indicators was the most.Effects of the sulphuric acid rain on chlorophyll in pakchoi leaves are the most and the chlorophyll content declines with the pH values of acid rain reduce.The contents of soluble sugar and vitamin C in pakchoi leaves grow with the increased sample days in all experimental.After harvesting,the two indicators reached the highest when the pH value of acid rain is 5.6.When the pH of acid rain is less than 5.6,the two nutritional indicators reduce with pH of acid rain declining.And the impact of nitric acid rain on the two nutritional is the most.
