摘　　要：掌握果树根系的组织结构和形态特征,对研究果树根系水分吸收与传导、阐明果树抗旱机理和促进水资源的高效利用具有重要意义。通过对果树根系结构、根系分布特征以及土壤水分对果树根系水分吸收与传导的影响进行综合分析,探讨了水分胁迫下根系水分吸收与传导的机理,以及分区交替灌溉对果树根区水分的影响。The understanding of the tissue structure and morphology of fruit tree roots would be of great influence in clarifing the mechanism of drought resistance of fruit trees and promotimg the efficiency use of water resources.A comprehensive analysis was conducted to the root structure of fruit trees,root distribution of tree roots and soil moisture on absorption and conduction of water in fruit tree roots,it explored the mechanism of water absorption and conduction in roots under water stress and the effect of partial root zone irrigation on the root zone water status.

关 键 词：根系结构 水分吸收 水分传导 根系分布 水分胁迫 交替灌溉
