摘要
以"乐都长辣椒"为试材,分析比较了不同电流强度和处理次数组合的等离子体技术对辣椒发芽率、生长势、产量等的影响。结果表明:适宜电流强度和处理次数的处理C(电流强度2A,处理次数为2次)和处理B(电流强度为1A,处理次数为3次)对辣椒种子的发芽率、生长势和产量有明显促进作用,电流强度弱或处理次数少的处理A(电流强度1A,处理次数2次)其促进作用不明显,而电流强度强或处理次数多的处理D(电流强度2A,处理次数3次)对辣椒发芽率、生长势和产量有一定抑制作用。综合各项指标,处理C对辣椒种子发芽率、生长势、产量等增加效果最明显,使"乐都长辣椒"的发芽率平均增加6个百分点,盛果期株高平均增高6cm,果长平均增加3cm,单果重平均增加34g,是最适宜的电流强度和处理次数。
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.
