我们知道,栽培扁桃种,普通扁桃(Amygdalus communis L.生产上称为扁桃、巴旦杏、巴旦木)是分布于我国新疆南部的一种珍贵的干果树,可是它是一种性喜温暖干燥的亚热带果树,在我国黄河流域南部的一些地区可以适应,有引种成功的可能,而在北部则由于冬季气温过低难以生存。那么要将扁桃栽培向北推进,必须培育耐寒的品种,而扁桃野生种是培育抗寒新品种的极有价值的基因库。同时,扁桃野生种也是为栽培扁桃探求矮化砧的丰富源泉。我国野生扁桃种类丰富,对这一自然资源进行调查研究,收集利用,将大大有助于我国扁桃生产 We know that cultivated almonds and common almonds (Amygdalus communis L. is called almond, almond, and almond) are a precious dried fruit tree distributed in southern Xinjiang, China, but it is a kind of warm and dry nature Subtropical fruit trees can be adapted in some areas in the southern part of the Yellow River basin of our country and are introduced successfully. However, in the north, it is difficult to survive due to the low winter temperatures. So to cultivate almond to the north to promote, we must cultivate hardy varieties, and Almond wild species is to cultivate a new genus of cold resistance of the extremely valuable gene pool. At the same time, the almonds wild species is also a rich source for the cultivation of almond trees dwarfing anvil. The variety of wild Almond in China is abundant. The investigation and study of this natural resource and the collection and utilization of it will greatly help the production of Almond in China
