摘 要:以番茄器官生长发育的生理生态过程为基础,建立了北方日光温室长季节番茄茎节生长模拟模型,它是建立番茄叶片和果实生长模拟模型的基础。供试番茄品种为"卡鲁索"和"卡特琳娜"。确定了模型中的参数如节点最大出现速率等,并对模型进行了验证试验。结果表明:番茄茎节数模拟值与实测值的变化趋势一致,平均相对误差为0.7%~9%。用散点图法验证模拟值与实测值的相关系数达0.9964,截距为-8.8,每平方米模拟值比实测值平均偏低8.8个茎节。表明模型模拟结果较好。A simulation model of stem growth of tomato in long season cultivation in solar greenhouse was developed based on the Ecophysiological Processes of tomato organ. The foundation on which Simulation Model of leaves and fruit of Tomato would be built was the simulation model of stem segments. The varieties were Caruso and Carter Lirma applied to long season cultivation in solar greenhouse. Some parameters such as maximum rate of node initiation were calculated or given. The results showed that the simulated and observed data of tomato stem were agreeable and the average relative error was 0.7%-9%. The correlation coefficients between simulated and observed data were 0.9964 and intercept was -8.8 in scatter chart, which meaned the simulated data was lower than the abserved data by 8.8. So the model has good performance.
