环剥技术在核桃管理中的应用研究

Application of Girdling Technology in Walnut Management

为了研究环剥技术在促进核桃开花、结果中的可行性,通过主干环剥、骨干环剥两种方式对种植于黔西南区域的核桃树进行环剥处理。结果表明:骨干环剥时,采用环剥口宽度2~3 cm,在主枝上进行环状环剥的方式对其混合花枝量促进作用最明显;主干环剥时,采用环剥口宽度1~2 cm的错位环剥,环剥弧长是干径周长2/3,在骨干上进行环剥的方式,对其混合花枝量促进作用最明显。在核桃树上实施环剥操作,能在一定程度上促进核桃混合花芽形成。

Here girdling technology was applied to promote the flowering and fruiting of walnut.Backbone and trunk girdling operations were then performed on the walnut trees that planted in southwest Guizhou Province of China.The feasibility of girdling technology was also evaluated in the test.The result show that the most outstanding performance was achieved to promote the amount of mixed flower branches:When girdling the backbone,the width of girdling mouth was 2~3 cm with the main branch;When girdling the trunk,the staggered girdling with a width of 1~2 cm was adopted with the girdling arc length of 2/3.Therefore,the girdling operation on walnut trees can be expected to significantly promote the formation of walnut mixed flower buds.
