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.展开更多
