The classical method to estimate the light conversion efficiency (εc) gives a single value for the whole crop cycle (εco) but does not reveal any variation along the growing season. We proposed the segmented approach to uncover such variations along sugarcane (Saccharum sp. hybrid) growth cycle. Our analyses revealed that longer sampling intervals could overestimate εco and that the segmented light conversion efficiency (εcs) varied between 0.09 and 5.39 g MJ-1 during the crop cycle. The εcs would provide insights on how the environment affects εc and how to increase biomass production through crop management practices.
经典方法估算的整个作物周期的光能转化率（εc）（εco）给出了一个单一的值，但并没有揭示出整个生长季节的任何变化。我们提出了分段方法来揭示甘蔗（Saccharum sp. hybrid）生长周期的这种变化。我们的分析表明，较长的采样间隔可能会高估εco，并且分段光能转化率（εcs）在作物周期内变化在 0.09 到 5.39 g MJ-1 之间。εcs 可以深入了解环境如何影响 εc 以及如何通过作物管理实践来提高生物量产量。
