摘　　要：试验对核桃(Juglans regia L.)品种辽核1号(J.regia cv.Liaohe No.1)进行输液滴干处理,比较了输液滴干、土壤施肥和常规管理3种方式对土壤含水量、核桃营养器官和果实生长发育的影响。结果表明,输液滴干处理的叶片SPAD值、叶面积、新梢长度和粗度、土壤含水量、果实品质、单果重、单株产量、抗性等指标均优于土壤施肥和常规管理,分别比土壤施肥处理和常规管理处理的单果重提高了13.93%、23.23%;单株产量分别提高了20.39%、75.27%;黑果率分别降低了88.97%、91.74%。The experiment was conducted to determine the influence of drip infusion in trunk, soil fertilization and regular management on soil water content, vegetative organs and fruit of Juglans regia L. cv. Liaohe No.1. The results showed that drip infusion in trunk significantly improved leaf SPAD value, leaf area, branch length and diameter, soil water content,fruit quality, single fruit weight, yield of each plant and resistance ability. Comparing with soil fertilization and conventional management, transfusion drip trunk increased the single fruit weight by 13.93% and 23.23% respectively; increased leaf SPAD amount by 20.39% and 75.27% respectively, and decreased black fruit rate by 88.97% and 91.74% respectively.
