The patterns of botanic root system exist in an obvious correlation with the organs over the ground,such as leaves,branches,and stalks.Different species present varied features which mirror biological habits of a species being in correlation with the pattern of its own structure.Related researches have shown that root number,weight,and diameter offer a close relationship with the corresponding parts over the ground,so that it is possible to simulate the root system image with the leaf-stalk image.;In accord...
