Fuzzy Synthetic Evaluation on Stalk-Like Crops with Biomechanical Properties Indices

Abstract

Based on the conclusions drawn from the systematically studying of the stalk biomechanical
properties indices of wheat planted in northern China (like wheat, corn, soybean, and millet),
the biomechanical evaluation indices system for stalk-like crops was built with the experts’
opinions. Seven indices of stalk were determined, including bending strength, bending
rigidity, cross sectional moment of inertia, Young’s modulus, impact ductility, tensile
strength and shear strength. Meanwhile, the judgment matrix was constructed by Delphi
Method and Analytic Hierarchy Process, and the results were acceptable by consistency
check. All of the indices weights were obtained, which were 0.376, 0.262, 0.153, 0.089,
0.060, 0.037 and 0.023, respectively. At last, the fuzzy synthetic judgment model for stalklike
crops was constructed with the fuzzy synthetic judgment method. Moreover, two
varieties of wheat were used as examples to validate the feasibility of the whole
biomechanical evaluation indices system and evaluation model.
