Abstract: The experiment shows that in favourable tea plantation ecoenvironments,the height,canopyscope,leaf area,diameter of main branches,length and weight of shoot and ratio of normalshoots of tea trees are higher than in unfavourable ecoenvironment.The production of teaand output value are 23.1% and 59.4% higher respectively.The quality of tea and the con-tents of polyphenol,amino acids and water extracts in tea leaves are also superior.It'simportant for tea production to protect and establish a favourable ecoenvironment in tea plantations.
