Simulation modeling of perennial fruit tree growth, structure, and physiology over multiple years is particularly difficult and has lagged behind modeling of other crops because fruit trees are indeterminate organisms that grow over several growing seasons, vary widely among individuals, and have their structures modified by variable pruning practices. Nearly 30 yr of research have been devoted to developing a mechanistic, virtual tree model to simulate peach [Prunus persica (L.) Batsch] fruit tree growth, structure, and physiology. Details of much of this work have been published in several research papers in a variety of journals over a couple decades. The goal of this review is to report on the entire project and provide an overview of the approach we took in such an endeavor. This review contains excerpts of numerous previously published papers and some comments and conclusions about the value of the modeling that has occurred.

使用 L 系统模拟果树生长、结构和生理

多年生果树生长、结构和生理的模拟建模特别困难，并且落后于其他作物的建模，因为果树是在几个生长季节生长的不确定的生物体，个体之间差异很大，并且它们的结构被改变可变修剪实践。近 30 年的研究致力于开发一种机械的虚拟树模型来模拟桃子 [ Prunus persica(L.)Batsch]果树生长、结构和生理学。几十年来，这项工作的大部分细节已发表在各种期刊的多篇研究论文中。本次审查的目的是报告整个项目并概述我们在此类努力中采用的方法。这篇评论包含许多以前发表的论文的摘录，以及一些关于已经发生的建模价值的评论和结论。
