摘　　要：为揭示杨梅矿质元素含量变化规律及分配特性,以东魁杨梅为材料,测定初果树和盛果树的不同器官在花期、幼果期、秋梢发生期和休眠期的矿质元素含量(包括N、P、K、Ca、Mg、S、Fe、Mn、B、Zn和Cu)。结果表明:N、K、Ca、Fe、Mn等矿质元素在不同器官和不同生长阶段的含量差异较大,P、S、Cu、Mg和B差异较小;初果树和盛果树的N含量均以叶最高,其次为枝。初果树的K含量以枝、叶较高;盛果树K元素含量在果实中最高,其次为枝、叶;Ca含量均以枝最高,在6 g·kg-1以上,而果实中Ca含量最低,在0.6 g·kg-1及以下;Mn含量均以叶、枝中较高;Fe含量均以根中较高;与初果树相比,盛果树各器官的N、Mn、Zn含量上升,P和Fe含量降低。试验结果可为杨梅生产中的矿质营养管理提供施肥原则。In order to reveal the variation and distribution characteristics of mineral elements in Chinese bayberry,8 years old young trees and adult fruit-bearing trees of Dongkui were used as plant materials,and mineral elements contents（ including N,P,K,Ca,Mg,S,Fe,Mn,B,Zn and Cu） in diffrent organs were investigated at florescence,young fruit stage,autumn growth period and dormant phase. The result suggested that contents of N,K,Ca,Fe and Mn varied greatly in different organs and different growth stages,and contents of P,S,Cu,Mg and B had no significant difference. Content of N was the highest in leaves of both the young trees and adult fruit-bearing trees,and followed by the branches. Content of K was much higher in branches and leaves of the young trees,and it was the highest in fruit of the adult fruit-bearing trees,followed by the branches and leaves. Content of Ca was the highest in branches,with the content higher than 6 g·kg-1; and it was the lowest in fruit,with the content less than 0. 6 g·kg-1. Content of Mn was much higher in leaves and branches,and content of Fe was much higher in roots. In the adult fruit-bearing trees,contents of N,Mn,Zn were increased,and contents of P,Fe were declined,when compared with the young trees. The results might provide principle of fertilization for management of mineral nutrition inthe production of Chinese bayberry.
