摘　　要：In Baiyushan hilly area, the roots system of almond-apricot mainly distributes vertically in the subsoil from 30 cm to 80 cm and horizontally distributes from 50 cm to 180 cm around the trunk. There are three growing peaks of the roots in a year and July-peak is the tallest one. From March to July is water losing period in subsoil of almond-apricot orchard, water losing is mainly from the aubsoil above 200 cm. There are three growing peaks for extending shoots and only one peak for fruit shoots in a vear. Fruit set percentage of almond-apricot is 15.61, of which short fruit branches are 22.62, long fruit branches are 8.56. Although there are differences in the growth of almond-apricot trees gown in slope lands with different elevation, aspects, and slopes, all trees grow well. Except frostbite harming, Baiyushan hilly area could be a better commodity production base of almond-apricot.In Baiyushan hilly area, the roots system of almond-apricot mainly distributes vertically in the subsoil from 30 cm to 80 cm and horizontally distributes from 50 cm to 180 cm around the trunk.
