本示范试验１９９１～１９９５年，在桃源县盘塘茶场进行。结果表明，运用低产茶园改造综合技术，取得了预期效果：（１）茶叶产量由１９９１年１０５０ｋｇ／公顷，上升到１９９４年２２５５．１０ｋｇ／公顷，增加１．１４倍；（２）茶叶品质，改造后的茶园比对照，正常芽叶提高３５个百分点，氨基酸提高２１．３７％，茶多酚提高４．３３％，水浸出物提高５．７０％，酚氨比下降１．８４；（３）茶园产值，除改造当年减少１６．１３％外，到第三年增加达２．０４倍以上，改造茶园投资全部收回。同时，带动了示范区周围茶园“低改”工作开展，具有明显的社会效益和生态效益。
The demonstration test from 1991 to 1995, in Taoyuan County Pan Tong Chachang. The results showed that the comprehensive technology of low yield tea plantation was used to achieve the expected results: (1) the output of tea increased from 1050 kg / ha in 1991 to 2255.10 kg / ha in 1994, an increase of 1.14 times; (2) The quality of tea, reformation Compared with the control, the normal tea leaves increased by 35%, the amino acid increased by 21.37%, the tea polyphenol increased by 4.33%, the water extract increased by 5.70% and the phenol / ammonia ratio decreased by 1.84. (3) The output value of tea plantations, except for the reduction of 16.13% in the year of rebuilding, will increase by 2.04 times or more in the third year and the investment in rebuilding tea farms will be fully recovered. At the same time, led the tea plantation around the “low change” work carried out, with obvious social and ecological benefits.
