通过对低产茶园进行台刈、重修剪、改植换种技术改造试验研究 ,结果表明 :技术改造后第 3年经济性状以重修剪表现好 ;单位产量重修剪比台刈、改植换种分别增产 4 8.4 kg和 58kg,差异极显著 ,台刈比改植换种增产 9.6 kg,差异不显著 ;第 4年重修剪、改植换种、台刈分别比对照(CK)增加经济效益 7.4 5,6 .4 3,6 .2 5倍。重修剪适宜于低产茶园技术改造。 The results showed that the economic traits of the low-yielding tea plantations during the 3rd year after the technical transformation were well re-pruned; the unit yield was more than the mowing and the replanting 4 8.4 kg and 58 kg respectively, the difference was extremely significant. The yield increase was 9.6 kg, the difference was not significant. In the fourth year, the pruning and replanting were changed, , 6 .4 3,6 .2 5 times. Heavy pruning suitable for low-yield tea plantation technological transformation.
