The invention discloses a three-dimensional morphological virtual modeling method of corn silk. The method comprises the following steps: observing the morphological structure of core silk and determining characteristic parameters of three-dimensional morphological of corn silk; establishing a three-dimensional virtual morphological model according to the characteristic parameters, wherein respectively carrying out modeling on silk axis, cluster stalk, spike stalk, bract and kernel. The three-dimensional morphological virtual modeling method combines the modern computer graphics technology and the modern algricultural science and production process, can realize three-dimensional display of silk on the computer for different corn varieties by setting model parameters, and has stronger realistic effect. The model has strong controllability and easy operation and can meet the requirements of digital design of the corn silk.
