麦田生态系中小麦生长亚模型的研究

The Study of the Wheat Growing Sudmodel in Wheat Field Ecosystem

本文利用前人的数据和自己的实验结果,构造了逐日模拟小麦生长的计算机模型,并用河南驻马店农科所7年试验结果对它作了初步验证,证明它可以较好地模拟正常管理条件下没有严重自然灾害时的小麦生长,可作为麦田管理最优决策模型的基础。

In this paper the modelling of a submodel of wheat field ecosystem is presented. Its inputing terms are basic wheather data (e. g. the daily highest and lowest tempre-ture, the day length), and the parameters which describe the characteristics of a wheat variety (like the maximum rate of photosynthesis, the heat summation of every growing stage, the distribution coefficients of the photosynthetic product in every growing stage, etc). The model is verified by seven-years' experimental data of Zhu-madiam Agricultural Institude, Henan, China. It proves that the model can preferably simulate the wheat growing if no serious natural calamities occur, and can be used as a foundation of support system designing decision for wheat field management.
