Analysis of the Force Characteristics of Stem to the Roots by SM Solver

Abstract:

Article Preview

To analogy and calculate the force distributed characteristic of external force of stem to transmition toward the root system by the SM Solver, and take the roots of Caragana microphylla Lam. and Artemisia sphaerocephala krasch. as the object of study in this paper. The results showed that the force of two plants mainly bears by the main roots, and the force of main roots decreases with the increase of soil depth. Force of main roots of Caragana microphylla Lam. and Artemisia sphaerocephala Krasch. at most reach 89℅ and 98℅ of external force of stem, Force of First-level roots of Caragana microphylla Lam. and Artemisia sphaerocephala Krasch. at most reach 14℅ and 10℅ of external force of stem, and that of second roots of Caragana microphylla Lam. and Artemisia sphaerocephala Krasch. is only 2℅ and 0.3℅. Force decreases with the increase of root length and depth, and the force increases with the increase of included angles between roots and vertical line.
