摘　　要：为了探索不同施肥处理对山地成龄核桃园中核桃树体生长和叶片内含物的影响,以“辽宁1号”核桃(Juglans regia)为试材,以节水节肥、提高树体营养为目标,以核桃生长期为基础,每个时期进行1次施肥,通过不同施肥组合的应用来筛选适宜的施肥时期。结果表明,所有水肥处理的树体生长指标、叶片营养指标和叶绿素含量均显著优于对照处理,传统的3次施肥处理在树体生长发育及叶片内含物方面表现较好,但叶片矿质元素、可溶性糖含量等指标与2次施肥处理差异不显著。1次施肥的所有指标显著低于3次施肥处理,说明适当减少水肥对核桃树体的生长及叶片的各项指标影响差异不大。综上所述,在生产中可以通过减少1次水肥来达到降低成本,节水节肥的目的。In order to explore the effects of different fertilization treatments on the growth and leaf contents of Juglans regia trees in the mature J.regia garden in mountainous areas,this experiment took"Liaoning No.1"J.regia as the test material,with the goal of saving water and fertilizer,improving tree nutrition as the target,and applied fertilization once in each period based on the growth period of J.regia.Through the application of different fertilization combinations to screen the appropriate fertilization period.The results showed that the tree growth index,leaf nutrient index and chlorophyll content of all water and fertilizer treatments were significantly better than those of the control treatment.The traditional three fertilization treatments had better performance in tree growth and leaf contents,but there was no significant difference between the two fertilization treatments in the indexes of leaf mineral elements and soluble sugar content.All the indexes of one fertilization were significantly lower than those of three fertilization treatments,indicating that appropriate reduction of water and fertilizer had little effect on the growth of J.regia tree and the indexes of leaves.In conclusion,it could be reduced by reducing one time of water and fertilizer to achieve the purpose of reducing costs,saving water and fertilizer in the production.
