为了量化研究温室番茄果穗间干物质的分配,提高温室番茄栽培的效益,采用源库生长单位的测定方法,将经典的单叶同化物生产模型与GreenLab模型相结合,构建了干物质向源库生长单位内茎节、叶片、果实分配的动态模型,利用越冬茬、早春茬和春夏茬温室番茄各器官的干物质测定数据对模型进行了验证.结果表明:所构建的模型模拟结果与实测结果吻合性较好,不同茬口同化物生产模拟值与实测值的回归方程斜率为0.93,R~2为0.92;源库生长单位内茎节、叶片、果实以及根系的模拟值与实测值间回归方程斜率在0.85～0.89之间,其相对误差(R_e)均值分别为5.3%、5.6%、8.1%和3.6%,说明模型的模拟准确度较高,可为不同茬口温室番茄栽培管理提供理论依据和决策支持.

To quantify dry matter partitioning among different fruit trusses and to improve production efficiency of greenhouse tomato, three experiments were carried out for over-winter, early-spring and spring-summer crops, respectively. Total dry weights of stem, leaves, fruits within a source-sink growth unit (one fruit truss and three leaves just below the truss) were measured during growing periods. A simulation model of total biomass and the partitioning among stems, leaves and fruits within a growth unit was constructed by combining a classical model of dry matter production in a leaf with the GreenLab model of dry matter partitioning. Our combined model was tested against measured data. The slope and coefficient of determination (R~2 ) between simulated and measured biomass of the whole plant for three experiments were 0.93 and 0.92, respectively. The slopes between simulated and measured dry weight of stems, leaves and fruits within source-sink growth units and dry weight of root of the plant were 0.85-0.89, and the relative error between them was 5.3%, 5.6%, 8.1% and 3.6%, respectively. These results suggested that our model could be used for optimizing fruit yield of greenhouse tomato production.
