番茄产量模型的仿真研究

Modeling and Simulating of Tomato Yield

研究优化控制番茄生产期和产量问题,针对目前新疆番茄种植生产期与加工环节之间存在的不匹配问题,提出了一种离散化的有序种植方案。在深入分析番茄产量的各种影响因素基础上,建立了基于静态变量和动态变量的番茄产量模型,并指出番茄产量是由动态参数修正静态初值得到的,静态变量决定了番茄的基本产量,而最终的产量是受动态变量控制的。给出了番茄产量模型的实现算法,通过算例仿真,验证了产量模型的正确性。仿真结果表明,提高耕种管理水平,不仅可以提高番茄的产量,还可以延长番茄的产出期,均衡产出期内的番茄产量。

Currently,there is a longstanding mismatch between planting and processing of tomato in Xinjiang.Aimed to solve this problem,a discrete ordered planting program was proposed.Based on an in-depth analysis of the various factors affecting the yield of tomato,the tomato production model was established,which introduced the static variables and dynamic variables.Analysis shows that tomato yield was obtained by the modification of the dynamic parameters to the static initial value.The static variables determined the basic output while the dynamic variables control the final output.Then,the realization algorithm for the model was issued and the correctness of the mode was demonstrated by several numerical examples.Simulation results show that increasing the level of farm management can not only improve the yield of tomato but also extend the output of tomato and balance the output during the period.
