摘要
根据三年的田间试验数据和有关气象资料,提出了马铃薯生育期和干物质积累的模拟模型,用高斯方程计算每天的温度条件对马铃薯生育期和干物质积累的生理效应,改进了前人的生育期模型和温度条件对干物质积累影响系数的计算方法。以每天的单位叶面积变化、群体上方的有效辐射和温度变化模拟群体的干物质积累。结果表明,本研究的模型有明确的机理性和较高的精度。用Visual Basic 6.0界面表达每日生态条件变化对群体光合生产和干物质积累的影响,模拟结果具有直观的机理性,从而克服了同类研究中的缺陷。
Based on three years field experimental data and referenced the former researches of crop phenology development and dry-matter accumulation modeling, the simulation model about potato phenology development and dry-matter accumulation are established in this study. The gauss carve is used to calculate the physiological effects daily thermal condition on potato phenology development and dry-matter accumulation. The dry-matter accumulation is driven by daily changed leaf area, temperature and effective solar radiation above the canopy. The simulation results show that the model is of high accuracy and clear mechanism. The model is edited with Visual Basic 6.0, which is rich of modeling interface. The simulation results given by the model is of direct and visible dynamical principle.
