落叶松的嫁接,已往采用的方法有髓心形成层法、双髓心法、斜接法等.由于落叶松枝条纤细,操作难度较高,技术不易掌握.另外,落叶松每株优树每年所能采到的接穗数量较少,一九七三年春我们在二十一株优树上采穗,平均每株优树砍掉中部以上侧枝五个,平均每个侧枝上可用于嫁接的接穗只有2-3个,费了很大气力,才采到接穗二百五十多个,远远满足不了良种繁育工作向前发展的需要.因此,我们根据落叶松针叶束可以抽出新枝条的特性,从一九七三年开始做了落叶松芽接的实验.
Larch grafting, the method used in the past with pith formation layer method, double pith center method, miter method, etc. Because of larch branches slender, the operation is more difficult, the technology is not easy to grasp.In addition, the larch trees per tree each year In the spring of 1973, we spawned twenty-one superior trees, and on average, each dominant tree cut off five branches above the central part, and on average, each branch can be used for grafting Only 2-3, spent a lot of effort, only to pick more than 250 scions, far can not meet the needs of the development of breeding thoroughbred. Therefore, according to larch needle bundle we can extract the characteristics of new branches , From 1973 experiment done larch budding.
