五针松一般以黑松为砧进行嫁接繁殖,但黑松有生长较缓慢的缺点。我们进行了以湿地松为砧木嫁接五针松实验探讨,取得了成功,具体方法如下。 1 砧木繁殖湿地松于91年春播种,92年春进行适当的间稀移植,嫁接时平均苗高40cm,粗度0.5—0.7cm。 2 嫁接时间和方法 92年7月9—10日嫁接,方法为腹接、撕皮嵌合接和切接三种。撕皮嵌合接。湿地松离地约4cm左右,去掉松针杂物,间隔0.2—0.3cm,纵向平行切两刀深达木质部,长约2—2.5cm,在上部横划一小刀,轻轻挑起皮向下撕,再取当年生五 Pinus pinaster to black pine as an anvil for grafting and reproduction, but the slow growth of black pine has the disadvantage. We conducted a wetland pine rootstocks grafted five pine experiment, and achieved success, the specific method is as follows. 1 rootstock Pinus elliottii sowing in the spring of 1991, the spring of 1992, the appropriate thinning between the grafting, the average height of 40cm when grafted, coarse 0.5-0.7cm. 2 grafting time and method 92, July 9-10 grafting, the method for the abdomen, torn skin chimeric then cut and then three. Tearing the skin fitting. Slash pine about 4cm away from the loose needle debris, interval 0.2-0.3cm, parallel to the longitudinal cut two knives deep xylem, about 2-2.5cm, in the upper row of a knife, gently stir up the skin to tear down, Then take five students then
