八角树高位嫁接矮化试验

High-level Grafted Low-height Test of Octagonal Tree

对老龄低产八角树进行高位嫁接矮化试验,结果表明,经嫁接的八角树,接穗在嫁接1年后可进入开花结果期,3年进入结果盛期,之后产量逐渐提高;对比不经嫁接的高龄低产八角树,产量成倍增长,增产非常明显;在主干和一级分枝嫁接的效果最好,其次是二级枝接;在三级及以上分枝嫁接,产量效果越来越差;推广八角高位嫁接矮化技术的应用,既能解决老龄低产的高大八角树因为太高导致的采摘困难问题,又能大幅提高产量。

High-level grafted low-yield octagonal tree was tested by high-level grafting. The results showed that the grafted octagonal tree could enter the flowering period one year after grafting, and the yield increased gradually after three years. Compared with the old low-yield octagonal tree without grafting, the yield increased by times, and the yield increase was obvious. Grafting in the main trunk and primary branch was the best, followed by secondary branching. Graft grafting at three levels or above, the yield effect is getting worse and worse. Promoting the application of octagonal high grafting low technology can not only solve the problem of tall octagonal tree with low yield due to old age, but also greatly increase the yield.
