摘要
建立了棉花群体光合生产和干物质积累模拟模型。其中,包括了作物叶面积动态、光能截获及光合与呼吸作用等主要生理过程,而且考虑了温度、肥料及其它绿色部分的影响。结果表明:模拟值与实测值的相关系数为0.9046,模拟误差为310.305kg/hm2。
Based on the theories of phsiology and meteorology, models of dry matter accumulation and photosynthesis were established. In these models, leaf area dynamic, light interception, phtosynthsis and respiration were included, and the effects of temperature, fertilizer and other green part were considered. The results of validation showed that, the correlation coefficient between simulated and observed values of dry matter accumulation was 0.9046, and the standard error was 310.305kg/hm 2.
