摘  要:
[目的]研究不同施肥处理对美国山核桃嫁接苗生长的影响。[方法]设置核桃专用肥、复合肥、尿素以及欧普基肥4种肥料17种不同施肥处理,研究不同施肥处理对其苗高、地径以及嫁接口粗度的影响。[结果]4种肥料各水平施肥后,均对嫁接口粗度和地径生长有促进作用,而核桃专用肥和复合肥仅在6 g/株施用量下对树高生长有促进作用。施用核桃专用肥6 g/株,尿素12 g/株,欧普基肥3g/株,复合肥6 g/株时对嫁接苗苗高、地径和嫁接口粗度生长的总体效果最好。[结论]合理施肥能够促进美国山核桃嫁接苗的生长。

摘  要:
[Objective] The aim was to study the effect of different fertilization treatments on growth of grafted Carya illinoensis.[Method] Setting 17 different fertilization treatments(4 types of fertilizers),the effect of different fertilization treatments on growth of grafted Carya illionensis were studied.[Result] The result showed that different treatment of four fertilizers had positive effect on the growth of diameter and grafted interface roughness.For walnut special fertilizer and compound fertilizer,only the treatment of 6 g/plant had a positive effect on tree height growth.Walnut specialty fertilizer with 6 g/plant,urea with 12 g/plant,Opl with 3 g/plant,compound with 6 g/plant were the optimal fertilizer treatments.[Conclusion] Rational fertilization could promote the growth of pecan grafted seedlings.
