苹果育苗中两种芽接方法的应用试验

通过对“丁字形”芽接法与带木质切腹嵌芽接法的对比试验，结合各类田间观察数据的统计分析，可以看出，在接穗与砧木都离皮的期间，用“丁字形”芽接法成活率高；砧木苗相对较细小，接穗或砧木任一有不离皮现象时，用带木质切腹嵌芽接，可当年完成嫁接任务；在大面积生产育苗中，用带木质切腹嵌芽接法嫁接，苗木成本比用“丁字形”芽接法嫁接低，经济效益相对较高。

Two type of budding in application trial of apples seedling raising

through the comparative trial of T budding and woodly inlay grafting, associating statistical analysis of all classes of field observation data, we think: T budding results in a high percentage of growing grafts when bark is slipping to both scion and rootstock; and it is better to use woodly inlay grafting when rootstock seedling is comparatively thinner and lower and either scion or rootstock has not the phenomenon of the bark slips because it can complete grafting task the same year ; but in massive productive seedling raising , the cost of nursery stock is lower using woodly inlay grafting than using T budding and economic benefit is higher.
