Abstract：In order to ascertain the adaptation of tea machine-picking in Yunnan, the single tea picking machine was applied in field for this experiment.Using one bud with one leaf and one bud with two leaves as standard, the variation of mechanical compositions of machine -picked tea shoots was investigated in four picking periods.The efficacy and cost of machine picking and artificial picking were comparatively analyzed, too.The results showed that under the application of NV60H single tea-picking machine, the oil consump-tion was the lowest and the intact leaf bud rate was 64.81%.Under the conditions of this experiment, when the standard bud and leaves occupied 70%~80%of new shoots in the canopy, the ratio of standard bud and leaves was 66.75%~72.73%of the fresh shoots picked by machine, so this period could be defined as the optimum machine-picking time.The application of machine picking in tea gardens could increase the efficacy by 10.42 times that of manual picking, and the picking cost could be saved by 84.25%.
