摘　　要：通过多年试验和大面积应用,核桃休眠期修剪对树势和结果无不良影响。从不同修剪时期的营养损失和剪后生长结果表现等方面,分析了核桃休眠期修剪的优点及可行性。The prevalent viewpoint is that walnut dormant pruning may cause nutrition loss,growth weakening or even twigs death due to bleeding.But by many year's experimental observation and wide application,it was found that walnut dormant pruning had more advantages in comparison with fall and spring pruning.In this paper walnut dormant pruning was inquired,analyzed and confirmed in the aspects of nutrition loss,tree growth,fruiting behavior and etc after pruning in different pruning periods.It was proposed that the dor- mant pruning should be adopted and extended in walnut production.
