摘要
根据“源 -库”理论及黄瓜生理学和作物生态学的基本原理 ,建立了温室黄瓜冠层光合生产和干物质积累模拟模型 ,模型由叶面积动态、光合作用、呼吸作用、干物质积累等子模型组成 ,模型中参数由相关文献和试验资料确定。通过收集国产温室黄瓜各生育时期干物质积累量对模型进行检验。结果表明 ,以光合作用为基础的干物质积累量模拟值与实测值的相对误差在 - 3.0 %～ 10 .0 %之间 ,说明所建立的模拟模型具有较高的精确性、机理性和实用性。
Based on 'resource sink', physiology in cucumber and agricultural aerography theory, a dynamic simulation model for photosynthesis and dry matter accumulation in greenhouse cucumber was established. The model consists of leaf area dynamic formation, canopy photosynthesis, respiration and dry matter accumulation formation. The model parameters were determined by related literature and the experimental data. The model was examined by the data collected from the experiments with measuring dry matter accumulation of the different development stages in the whole development process in greenhouse cucumber. The results showed the relative prediction errors for dry matter accumulation in the different development stages between simulated values and measured values ranged within -3.0%~10.0%. This simulation model was of high accuracy, more mechanism and practicabitity.
