蟹爪兰等仙人掌类花卉的嫁接及成活,与其它科属的花卉有很大不同。以蟹爪兰而言,当嫁接完成后,在适宜的光、温、湿条件下,接穗的嫁接部位会尽快将处于休眠状态的不定根转化为实生根并扎入砧木组织,吸收砧木根系输送的水分和养分,进而成活。而不定根的抽生相对集中在接穗节片的上下顶端,因此接穗处理的刀法,对嫁接能否成活及成活后的长势非常重要。笔者通过多年的观察与探索,归纳出五种基本刀法(见图1): A是待嫁接的原始接穗,嫁接部节片分为下根点、嫁接主体组织和上根点三部分,其中1、3位置为抽生不
Gramineae and other cactus flowers grafting and survival, and other genera of flowers are very different. In the case of Semen Koch, when the grafting is completed, the adventitious roots in the dormant state will be transformed into rooted roots and rootstock tissues as soon as possible under appropriate light, temperature and humidity conditions, and the roots of the rootstocks will be absorbed Water and nutrients, and then survive. The adventitious root pumping relatively concentrated in the upper and lower scion section of the top, so the knife method of scion, grafting survival and survival is very important. Through years of observation and exploration, the author summed up five basic knife methods (see Figure 1): A is the original scion to be grafted, grafting section is divided into the next root point, the main body of grafting and the root of three parts, of which 1,3 for the pumping position is not
