Abstract: The experiment result showed that the illumination intensity on tea plants was be weakened by chestnut-tea tree intercropping in the north of China. The air temperature and soil temperature in the space of trees effectively reduced and the air humidity stably increased, so that the tea quality and yield had been improved. So it is suitable to spread this technology in the north of China.

Key words: Chestnut-tea tree intercropping, Chestnut-tea tree intercropping, Micro climate, Benefit
