A differential equation model of vegetative growth of the soya bean plant (Glycine max (L.) Merrill cv. Ransom') was developed to account for plant growth in a phytotron system under variation of root temperature and nitrogen concentration in nutrient solution. The model was tested by comparing model outputs with data from four different experiments. Model predictions agreed fairly well with measured plant performance over a wide range of root temperatures and over a range of nitrogen concentrations in nutrient solution between 0.5 and 10.0 mmol NO3- in the phytotron environment. Sensitivity analyses revealed that the model was most sensitive to changes in parameters relating to carbohydrate concentration in the plant and nitrogen uptake rate.
建立了大豆植株（甘氨酸max（L.） Merrill品种‘Ransom’）营养生长的微分方程模型，以解释在人工气候室系统中，根温与营养液中氮浓度变化情况下的植株生长情况。通过将模型输出与来自四个不同实验的数据进行比较，对该模型进行了测试。在人工气候室环境中，模型预测在很宽的根温范围内以及营养液中氮浓度介于0.5至10.0 mmol NO3-之间的范围内，与实测的植株性能相当吻合。敏感性分析表明，该模型对与植株碳水化合物浓度和氮吸收速率相关的参数变化最为敏感。
