【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。更多还原

【Abstract】 Based on"resource-sink",physiology in cucumber and agricultural aerography theory,a dynam ic simulation model forphotosynthesis and drymatter accumulation in greenhouse cucumber was established.The model consists of leaf area dynam ic formation,canopy photosynthesis,respiration and dry matter accumulation formation. The model parameters were determined by related literature and the expermental data.Themodelwas exam ined by the data collected from the experiments with measuring drymatter accumulation of the different development stages in thewhole development process in greenhouse cucumber.The results showed the relative prediction errors for dry matter accumulation in the different devebpment stages between simulated values and measured values ranged with in -3.0%～10.0%.This simulation modelwas of high accuracy,moremechanism and practicabitity.更多还原
