摘　　要：以早实核桃"香玲"、"西林3号"和晚实核桃"西洛3号"为试材,研究了不同修剪技术对不同品种核桃母枝萌发和枝条生长的影响,以及留桩与干桩的相关性。结果表明:早实核桃采穗圃修剪以轻短截(留桩≥30cm)较好,晚实核桃则以重短截(留桩≤20cm)为宜。Taking two precocious walnut ＇ Xiangling＇, ＇ Xilin No. 3＇ and one serotinous walnut ＇ Xiluo No. 3 ＇ as materials, the effect of the different pruning methods on the germination of different walnut base branch and the growth of the branch,as well as the correlation between the length of leaving stake and the length of dead stake were studied. The results showed that,in walnut scion orchard,light pruning（length of leaving stake was more than 30 cm） was better for precocious walnut ;heavy pruning（length of leaving stake was less than 20 cm） was better for serotinous walnut.
