This paper studies the vertical tensile strength of whole tree roots under the same soil and landformconditions. The experiments show that the shape of a root system’s distribution affects the verticaltensile strength of roots. Rhododendron trees have horizontal root systems, so the whole roots werepulled out in the experiment process. Populous purdomii has vertical roots, so the experimentcontinued quite a long time. Abies fabric has both vertical and horizontal main roots, so the P--Scurve shows a multi--peak shape.
