双季稻光合生产模型的建立与应用
Establishment and application of photosynthetic production model for double cropping rice
摘要
Abstract
In this study,we developed a model for photosynthetic production in double cropping rice by integrating the advantages in current crop models (including the models of canopy structure,canopy light distribution,canopy photosynthesis and dry matter production).The canopy light distribution and dry matter accumulation were preliminarily validated with independent field experiment datasets.The distribution of direct radiation both on a level surface and on the leaf surface within canopy,the canopy daily photosynthate and its characteristics with varying leaf area index for three typical plant types (erect both upper and lower,upper erect and lower flat,and flat both upper and lower) were quantitatively analyzed by the model.The results indicated that there was a good agreement between the simulated and observed values.The root mean square error (RMSE),relative root mean square error (RRMSE) and correlation coefficient (r) of prediction of canopy light distribution in double cropping rice were 12.01 J · m-2 · s-1,8.2％ and 0.9929,respectively.Meanwhile,the RMSE,RRMSE and r of prediction of dry matter accumulation were 0.83 t · hm-2,14.6％ and 0.9772,respectively.It was indicated that the model had a performance.The upper erect and lower flat plant type had highest canopy daily photosynthate due to higher incident sun light received on the leaf surface,leaf photosynthetic efficiency and leaf area index.关键词
