Abstract:

The mixed simulated acid rain solutions at different pH levels were spayed on pakchoi in different spray ways within the greenhouse. The results show that strong acid rain inhibits the formation of the nutrients in the cabbage, while week acid rain increases the formation of the nutrients in the pakchoi. Among the three spay ways, more spray amounts and longer spray intervals in the single spray ways have the bigger influence on the quality of pakchoi nutrition.

Key words: simulated acid rain, different acid rain spray way, soluble sugar, vitamin C
