球类仙人掌嫁接多采用平接法,刀法简单,切削容易,但砧、穗维管束不易很好对接,且易使接穗移位,不易捆绑固定。笔者采用“V”形接法,很好地克服了平接法的不足。做法是:将砧木和接穗的接触面不削成平面,而是略削成“V”字形,即将砧木和接穗一个削成凹“V”字形,一个削成凸“V”(即“A”)字形,且砧、穗维管束都位于“V”字的顶点上。凹凸深浅大小适宜,便于二者很好吻合。削好后使二者维管束对齐,然后捆绑或加压固定即可,务使二者维管束密切接触。其他均按平接法处理。
Ball cactus grafting and more use of flat law, the knife method is simple, easy cutting, but the anvil, spike vascular bundle is not easy docking, and easy to shift the scion, not easy to bundle fixed. The author adopts “V ” shaped connection, well overcome the lack of connection. Practice is: the rootstock and scion contact surface is not cut into a flat, but slightly cut into “V” shape, the stock and scion will be cut into a concave “V” shape, a cut into convex “V ”(Ie,“ A ”) glyph, and anvil, ear vascular bundle are located in the“ V ”word vertices. Bump depth appropriate size, easy to fit the two very well. After sharpening the two vascular bundle alignment, and then bundled or pressurized can be fixed, in order to maintain close contact between the two vascular bundle. Others are processed by the flat connection method.
