Resumen

This study employs virtual plants as a bridge between them to achieve the goal of merging the ongoing development of computer technology with modern agriculture. Virtual plants are a new study subject that has emerged in recent years as information technology and computer technology have advanced rapidly. It is a multidisciplinary field that combines computer graphics, botany, mathematics, and virtual reality technologies. This work proposes a method for visualizing fruit tree branches and stems using morphological feature information and the parameter L system. The relevant morphological and structural characteristics, as well as ecological and physiological characteristics, were extracted from the pear tree's tree structure; the L-system modeling method was used to create a model of the pear tree, which included details such as branch thickness, bifurcation angle, and so on; The geometric information of pear tree growth is turned into intuitive three-dimensional visual graphic information using three-dimensional modeling technology, laying the groundwork for the construction of a pear tree shape and pruning computer simulation system. Furthermore, the yield per unit area of an open center tree is 73.93 percent, the weight of a single fruit is 84.22 percent, and the rate of high-quality fruit is 76.15 percent, all of which are less than 85 percent, according to the real test. Only the soluble sugar content, soluble solid content, and fruit hardness relative values are greater than 90%.
