扦插繁殖法用得很普遍,但成活率却因人而异。笔者认为,扦插中注意这么几点,有利于提高成活率:1.取插穗(根、茎、叶)不要用剪刀,要用刀(刮胡刀片或手术刀)。取插穗木本用剪刀,草本用手掐,恐怕已是人们习以为常的事。不少书中关于取插穗也是用“剪下”、“取下”、“剪断”等说法,很少提到用刀。人们忽视了这样一个问题,即用剪刀剪或用手掐时,已使要取的插穗受到挤压了,有的甚至挤压劈了,破坏了插穗本身的细胞组织。这一点有时肉眼看不到,但用倍数较大的放大镜可以看清楚,所以取插穗要 Cutting propagation method used very common, but the survival rate varies from person to person. The author believes that cuttings pay attention to these points, help to improve the survival rate: 1. Take cuttings (roots, stems, leaves) do not use scissors, use a knife (razor blade or scalpel). Take the scissors with woodcutters, herbs hand pinch, I am afraid that people are accustomed to things. Quite a few books on the use of cuttings is also used “cut ”, “remove ”, “cut off ” and so on, rarely mentioned knife. One overlooks the problem that the cuttings to be taken have been squeezed when they are cut with scissors or handcuffs, and some are even crushed and severed the tissue of the cuttings themselves.
