Abstract:
With the 3—4 year-old Caragana intermedia,Hippophae rhamnoides as the research objects,the same diameter straight root and lateral root’s bending mechanical characteristics through the cantilever beam test were studied.The results showed that,bending force of two plants’ straight root and lateral root showed a positive power function relation to diameter.The bending strength had no law to diameter,fluctuating around the average.The same plant of average bending force and bending strength showed that straight root was greater than the same diameter lateral root during most diameter level range.At the same diameter,when straight root and lateral root’s diameter>2.5 mm,the bending force and bending strength of the two plants comparead:Caragana intermedia>Hippophae rhamnoide.The bending strength about Caragana intermedia straight root was about 1.12 times of Hippophae rhamnoides straight root.The bending strength about Caragana intermedia lateral root was about 1.04 times of Hippophae rhamnoides lateral root.
