摘　　要：1987～1989年探讨了锦橙(Citrus Sinensis Osbeck)的矿质营养元素含量标准值。结果表明,锦橙叶片营养元素适宜含量指标为:N2.75～3.25,P0.14～0.17,K0.7～1.5,Ca3.2～5.5,Mg0.2～0.5%,Fe60～170,Zn13～20,Mn20～40,Cu4～8,B40～110ppm。其中,大量元素的适宜比值为:N:P:K:Ca:Mg=1:0.052:0.37:1.45:0.12,可作为指导合理施肥的参考。Tests were carried out in 1987—1989 to determine the leaf nutrientrate standards for Jinchen orange (Citrus sinensis Osbeck).Theoptimum levels were determined to be 2.75—3.25% for N,0.14—0.17%for P,0.7—1.5% for K,3.2—5.5% for Ca,0.2—0.5% for Mg,60—170ppmfor Fe,13—20ppm for Zn,20—40ppm for Mn,4—8ppm for Cu and 40—110pmp for B,while the desirable ratio for the above-listedmacroelements N,P,K,Ca and Mg appeared to be 1∶0.052∶0.37∶1.45∶0.12.
