“T”字形芽接是最常用的一种嫁接方法,但在实际操作中,却遇到了许多问题,如接穗在未完全离皮时,不能用此法削取接芽;再如,不能解决小砧木、大接穗嫁接时所带来的困难等。而用改良“T”字形削取接芽的方法,可有效地克服上述缺点。 此法选用的试验材料:砧木为当年培育的实生海棠苗,接穗是当年生键壮的新梢。嫁接品种为王林和新红星。92、93两年各试验50株,成活率分别为98％、100％。
“T” shaped budding is the most commonly used method of grafting, but in actual operation, but encountered many problems, such as the scion is not completely from the skin, can not use this method to pick the bud; Another example, can not solve the small Rootstocks, scion grafting difficulties and so on. But with the improved “T” shape cut access bud method, can effectively overcome the above shortcomings. This method of selection of test materials: rootstocks for the current year to cultivate Begonia seedlings, scion is the key year of strong shoots. Grafted varieties Wang Lin and new red star. 92,93 two trials of 50, the survival rates were 98%, 100%.
