摘　　要：将罗伯逊脐橙 36号、锦橙和国庆 1号温州蜜柑作为长果形纽荷尔脐橙的中间砧 (基砧为枳 )进行田间试验研究 ,结果表明 :罗伯逊脐橙 36号的冠幅和树冠体积最小 ;锦橙的春梢和夏梢生长量均最小 ,而秋梢则反之 ;中间砧粗度和接穗粗度均表现为锦橙、罗伯逊脐橙 36号、国庆 1号依次递减 ;3种中间砧与接穗在亲和性上无显著的差异。罗伯逊脐橙 36号花量过大 ,国庆 1号花量过小 ,锦橙花量适中且单株产量最高。罗伯逊脐橙 36号在果实综合品质表现上略好。 3种中间砧对叶片光合色素含量与相对组成有显著的影响 ;对叶片糖分含量有明显的影响。对叶片P含量影响无显著性差异 ,对叶片的N、K、Fe。Through the research of field experiment on Robertson 36( Citrus sinensis Osbeck cv. Robertson 36) ?Jincheng( C. sinensis Osbeck cv. Jincheng)?Guoqing No.1( C. unshiu Tanaka cv. Guoqing No.1) as the interstocks for the long fruit shaped Newhall orange,the results showed as follows: Robertson 36 had significantly smaller crown diameter and canopy volume than that of the other two spring shoots and summer shoots of Jincheng were shorter than that of the other two , but the autumn shoots were to the contrary;the diameters of the interstocks and the scion became smaller in turns of Jincheng?Robertson 36?Guoqing No.1; the compatibility between the three kinds of interstock and the scion had no remarkable difference.On the flower ammount, Robertson 36 was too large, and Guoqing No.1 was too small, and Jincheng was exact;meanwhile,Jincheng had the highest average yield per single tree. Robertson 36 seemed to have better integrated quality than the other two. Three kinds of interstock significantly influenced the concentration of the photosynthesis pigments affected the concentrations of leaf's carbohydrates. The concentration of P of leaf had no remarkable difference among three kinds of interstock, which made the concentrations of N, P, K, Ca and Fe make noted difference.
