基于涡度相关通量数据估算水稻光能利用率
Light use efficiency estimation of rice using eddy covariance flux data
摘要
Abstract
The light use efficiency was used to estimate eddy covariance flux data of irrigated rice from jointing to mature period in Shouxian,Anhui Province,and the daily and seasonal variation of light use efficiency were also analyzed.The results suggest that the daily variation of light use efficiency first decreases then increases as a single peak U curve,which is higher at dawn and in the evening,lower at noon.Light use efficiency decreases with seasonal change.In daily variation,light use efficiency is positively correlated with temperature,but negatively correlated with absorbed photosynthetic active radiation.In seasonal variation,light use efficiency is positively correlated with temperature.关键词
