Abstract: Effects of outer shading screens on tea ecology and physiology in red soil hilly region were studied.The results showed that when the tea plantation was covered with outer shading screens during the hot-dry season,the temperatures of atmosphere,tea crown,tea leaf surface,soil surface and soil at every observational time were lower apparently than those of tea plantation without screens.The soil water content,atmosphere humidity and leaf water content in tea plantation with screens were much higher; and the contents of chlorophyll,caffeine and amino acids increased significantly while the polyphenol content decreased by 11.6%.After 27~29 days of continuous hot-dry weather,the transpiration rate,stomatal conductance and net photosynthetic rate of tea with screens were obviously higher than those of tea plantation without screens.
Key words: Fuxian Lake, Constructed wetland, Phosphorous removal efficiency
