摘　　要：长期以来对作物地上部分的结构功能和叶光系统进行了大量研究,对向日葵的根系发育规律的研究相对较少,盐渍化地区向日葵根系发育规律的研究就更少。为了有效地研究油料向日葵根系吸水过程和根系分布的关系,本文对向日葵根系生长发育规律和根系密度分布进行研究。So far, there are not so many literatures that deal with plant root system compared with that above the ground. A few of them are related with growing abilities in salty soil. This research focuses on the root growing regulation, density, and distribution of sunflower in salty soil in order to analyse the relationship of its water absorbing processes and distribution.

关 键 词：作物根系 盐渍化 根系吸水 根系密度
