一、砧木与接穗的选择砧木、接穗最好用同一树种。用本砧嫁接成活率高,生长旺,寿命长,不会产生不亲和现象。但有些树种如圆柏、粉柏、龙柏等的种子发芽率低,苗木生长慢,投资较高。对这些树种,可选用侧柏苗做砧木。五针松嫁接可选用油松作砧木。砧木的年龄应视树种枝条的粗细而定。油松、华山松、樟子松等树种,当年生枝条粗壮,一般租0.5～1cm。嫁接适宜选2～3年生的同种苗木作砧木。圆柏枝条较细,嫁接时用侧柏百日苗做砧木最合适。
First, the choice of rootstocks and scions Rootstocks, scion best to use the same species. Grafting with this anvil high survival rate, growth Wang, long life expectancy, will not have the phenomenon of incompatibility. However, some species such as Sabina, powder Parkinson, Cypress and other seed germination rate is low, slow growth of seedlings, higher investment. For these species, Arborvitae seedlings can be used as stock. Five needles pine grafting can be used as rootstock. The age of rootstocks should depend on the thickness of tree branches. Pinus tabulaeformis, Pinus armandi, Pinus sylvestris and other tree species, when the branches thick, generally rent 0.5 ~ 1cm. Suitable for grafting 2 to 3 years of the same seedlings for rootstock. Circular arborvitae twigs thinner, Arborvitae grafted with rootstocks do best.
