Many support types for apple trees such as single support, fence type and matrix type have been used. However, there is no standard type designed or specified by a code or manual, and most farmers build the supports arbitrarily. A standard fence type among some supports was proposed and modeled in the software of Midas Gen. Input load acting on the poles in numerical analysis was obtained the wind tunnel test for apple trees. The appropriate section sizes of internal and external poles in fence type support were determined according to the wind velocities. |
