摘要:
以6年生‘清香’核桃为试材，在落叶前（PBD）、落叶后（PAD）、严冬期（WP）、萌芽前（PBG）和萌芽后（PAG）等不同时期修剪，并以不修剪为对照（CK），研究了不同时期修剪对核桃叶片主要营养元素周年动态变化规律的影响，以期为核桃合理修剪时期的确立提供参考依据。结果表明：在N、P、K、Ca、Mg含量上，各处理间无显著差异，而在Fe、Mn、Zn、Cu含量上，PAD表现突出，常常处于最高水平，PAG、PBD表现次之，WP则表现较差。故此，修剪时期以PAD最佳，PAG、PBD次之，WP最差。
Abstract:
The cultivar of 6-year-old ‘Qingxiang’ walnut was used as material and pruned respectively in different time.The pruning periods were pruning before defoliation（PBD）,pruning after defoliation（PAD）,winter pruning（WP）,pruning before germination（PBG）,pruning after germination（PAG） and untrimmed（CK）.The effect of different pruning period on seasonal changes of nutrient elements content of walnut leaves were studied in order to provide reasonable reference for pruning period of walnut.The results showed that contents of N,P,K,Ca and Mg in leaves among different pruning time was no significant difference.Contents of Fe,Mn,Zn and Cu in leaves after pruning were superior to CK,and were distinctly higher in leaves of PAD and relatively low in leaves of PAG and PBD,lowest in leaves of WP.Thus the best pruning time was PAD,next were PAG and PBD.The effect of WP was the worst.
