摘要
用改良壕沟法对两个杏品种根系分布进行观察.六个剖面的观察结果表明,杏根系较苹果、桃、山楂等树种根系分布深.根系主要分布在地表下10～90cm的土层内,根系分布的深度和广度受土壤质地影响.
The distribution of root systems of two apricot species was observed by the Oskamp method. The results of observation on 6 profiles showed that apricot root system distributed in the layer 10 to 90 cm below the surface, deeper than those of apple, peach, and hawthorn. The depth and range of root distribution were affected by soil texture.
