The invention relates to a test bench for a tea-picking mechanism of a tea garden. The test bench comprises a machine frame, a power source and a traveling mechanism for driving the horizontal movement of the machine frame, wherein the machine frame comprises a left upright column, a right upright column and a crossbeam; a lifting frame and a lifting mechanism are arranged between the left upright column and the right upright column; the lifting mechanism is used for driving the movement of the lifting frame; a mounting port is formed in the front end of the lifting frame; a power output port is formed in the mounting port; a leaf collecting mesh bag which is used for collecting tea leaves picked by the tea-picking mechanism is further arranged on the lifting frame; a fan is arranged on the machine frame; an air supply box body is arranged on the lifting frame; air output by the air supply box body is suitable for blowing the tea leaves picked by the tea-picking mechanism into the leaf collecting mesh bag; the traveling mechanism, the lifting mechanism, the fan and the power output port are driven by a power source respectively. According to the test bench, various factors for influencing the tea-picking quality of a tea-picking machine can be conveniently verified, and the research/development level and the research/development quality of the tea-picking machine are improved.
