Abstract:

Yield and quality are improved by the technology of low yield tea garden comprehensive transformation in Tie-guanyin, that had significance for stable and promoting oolong industry. The effect of Tie-guanyin low yield tea garden comprehensive transformation was analyzed in Yuanchang base and tea research institute base in Anxi. Results showed that variety purity was (97.6±0.603)%-(99.5±0.467)% after purification in Tie-guanyin low yield tea garden, seedling purity was (99.9±0.067)% higher 9.7% than those without purification, the differences of purification results with control were very significant. After transformation, the soil pH was significantly increased for the trial, and mean were 4.64 and 5.06 respectively. The means of Tie-guanyin planting survival rate were (99.3±0.513)% and (99.5±0.5)% respectively, which higher 5.13%~9.17% than the old tea garden, the differences were significant. The yield had increased 10% in second year and 15% in third year; effect on yield increase was obvious. Quality score was higher 3.05~9.46 than control after comprehensive transformation, the differences were very significant or significant, and the quality was increased one grade averagely.
