香榧种砧嫁接是将接穗直接插入子叶合缝线内的一种嫁接方法,这在我国嫁接技术上尚是首次报导。其主要方法是:采集成熟种子,经湿沙贮藏完成生理后熟并层积催芽,胚根长1.5厘米左右时作种砧;选取优树树冠外围发育健壮的一年生侧枝作接穗,穗长10～15厘米,粗0.25～0.3厘米,楔形削面长1.2厘米;冬季接后假植,翌春移植圃地,成活率可达80％以上,成苗率可达76％以上。育苗时间比普通枝接苗缩短2～3年,成本降低50％左右。同时,催芽、嫁接、假植工序可在室内进行,操作简便,易为群众掌握,是一项适合生产上推广应用的嫁接新技术。
Fragrant pestle species anvil grafting is the scion directly into the cotyledons within a kind of grafting method, which is still the first time in our grafting technology. The main method is: collecting mature seeds, after wet sand storage to complete the physiological and ripening and stratified germination, when the radicle length of about 1.5 cm as an anvil; select superior tree crown periphery healthy sturdy annual branches for scion, spike length of 10 ~ 15 centimeters, 0.25-0.3 centimeters thick, wedge-shaped cut 1.2-m long; winter then planted, the next spring transplant nursery land, the survival rate of up to 80%, more than 76% of the seedling rate. Nursery seedlings shorter than the average 2 to 3 years, cost reduction of about 50%. At the same time, germination, grafting, fake planting process can be carried out in the room, easy to operate, easy to grasp for the masses, is a suitable production for the promotion of new grafting technology.
