Taking ‘Ledou long pepper’ as material,characters and output of pepper were determined after treated with different combinations of electric current intensity and treatment times.The results showed that treatment C(2 A current intensity and 2 treatment)and treatment B(1 A current intensity and 3 treatments) were the suitable combinations of electric current intensity and treatment times,and they had the role in promoting of germination rate,plant growth and output.The role in promoting of germination rate,plant growth and output when treated with lower current intensity and fewer treatment A(1 A current intensity and 2 treatments) was not obvioue.But the plasma had inhibition on the seeds germination rate,plant growth and output when treated with stronger current intensity and more treatment.All the indicators,treatment C was the most obvious combinations according to the test of germination rate,plant growth and output;germination rate of ‘Ledou long pepper’ was average increased 6%,the plant height was average increased 6 cm in flourishing time,the fruit length was average increased 3 cm,the fruit weight was average increased 34 g.It was the most suitable combination of electric current intensity and treatment times.
