摘　　要：Armeniaca vulgaris × A. sibirica is a new almond-apricot species of Armeniaca genus in Baiyushan mountainous area of northern Shaanxi that introduced from Zhuolu County, Hebei Province 12 years ago. After 11 years investigated and observed, the florescence of A. vulgaris × A. sibirica is the earliest and the shortest compared with A. vulgaris , A. vulgaris var . ansu and A.sibirica ; the number of non-harvest year caused by frost is the most; number of root is the least, and root distribution is lowest and narrowest; trunk diameter, height, and crown diameter are the least; almond is changed smaller and smaller with the tree age increased; production of stone is lower than A. vulgaris var . ansu and A.sibirica ; in small hilly region and medium mountain regionⅠ, production value is lower than A. vulgaris and higher than A. vulgaris var . ansu and A.sibirica ; in medium mountain regionⅡ, production value is lower than A. vulgaris var . ansu and A.sibirica ,very lower than A. vulgaris . A. vulgaris × A. sibirica shouldn’t be a dominating species in Baiyushan mountainous area.Armeniaca vulgaris × A. sibirica is a new alnlond-apricot species of Armeniaca genus in Baiyushan mountainous area of northern Shaanxi that introduced from Zhuolu County, Hebei Province 12 years ago.
