以早实良种核桃“香玲”为试材,分析了不同修剪方式对新梢及有效穗芽的影响。结果表明:不同留桩长度对“香玲”核桃新生枝条数量、长度、直径、穗芽数存在极显著的影响;穗芽的产量受到新生枝枝条数量、长度、直径、二次枝发生率的综合影响;陕南地区“香玲”核桃穗芽萌芽前修剪留桩长度以10~20cm为佳,平均有效穗芽产量比不修剪增加了583.2个,提高了116.8%;留桩长度越短,新生枝条长度生长高峰越滞后。
The effect of different pruning methods on shoots and effective ears of sprouts was analyzed with “Qianling”, a seed of premature seed. The results showed that different length of stubble had a very significant effect on the number, length, diameter and number of sprouts of new branches of walnut in “Hongling”. The yield of sprouts was affected by the number, length, diameter of new branches, The average effective spike bud output increased by 583.2 compared with no pruning, increased by 116.8%. The number of left-handed pile The shorter the length, the lagged the growth of new branches.
