摘　　要：为给美国山核桃丰产栽培提供技术支持,以鸡粪、猪粪、复合肥为肥料,研究不同施肥配方对美国山核桃生长的影响。结果表明,施用猪粪5kg/株对美国山核桃树高、地径和一级枝条长度和粗度增长效果最为明显,其次为鸡粪5kg/株和鸡粪2.5kg/株+猪粪2.5kg/株2个处理,对照处理效果最差。各处理对枝下高、嫁接口径粗和一级分枝数无显著影响。In order to provide technical support for high-yield cultivation of Carya illinoensis,effects of different fertilization treatments on growth of C.illinoensis,taking chicken manure,pig manure and compound fertilizer as basis fertilizers.The results showed that applying 5kg pig manure per plant had the most significant effects on tree height,ground diameter,first-order branch length and diameter in C.illinoensis.And then the treatments of applying 5kg chicken manure and applying 2.5kg chicken manure ＋ 2.5kg pig manure had better effects,and CK had the worst effects.All treatments had no significant effects on clear length,grafting incision diameter and first-order branch number.
