高接在不同基砧的锦橙上的华红脐橙的栽培表现及矿质营养含量年变化

田间调查了高接在两种不同基砧的锦橙上的华红脐橙的栽培表现及矿质营养含量年变化差异。结果表明,在栽培效应上,红桔基砧树体生长较旺,投产晚,果实小,果实含酸量较高、糖酸比较低,出汁率和Vc含量较高;枳基砧则相反。在矿质元素含量年变化上,不同基砧树的叶片矿质元素含量年变化趋势除Mn、Zn外,其它元素含量年变化趋势差异明显;不同基砧根系的各种矿质元素含量年变化趋势基本相似;在不同基砧树之间,除根系Mg、Fe含量外,叶片和根系的各种矿质元素含量在年周期内的差异明显。

Study on performance of Huahong navel orange grafted to Jincheng with two kinds of rootstock and annual changes of mineral elements content

Through the field investigation after huahong navel orange grafted on jincheng with trifoliate orange and red tangerine, comparing performance of huahong navel orange and annual changes in the contents of mineral elements with each other. The results indicated that huahong navel orange on red tangerine grew flourishingly, and put into product late, and had smaller fruit with higher total acid(TA) and lower ratio of total soluble sugar to total acid(TSS/TA) and higher percent of juice and content of Vc, and contrary on trifoliate orange. The tendency of annual changes in the contents of mineral elements except Mn and Zn in leaf had noted difference between 2 kinds of rootstock, and that in root basically coincided with each other. The difference in the contents of all mineral elements in leaf or in root between 2 kinds of rootstock were obvious during the year except Mg and Fe in root.
