Title: Simulation of Canopy Photosynthetic Production Based on Plant Type in Rice
Abstract: By using canopy-light-distribution-based photosynthetic model,and designing various combinations of model input parameters for compact and loose plant types of rice,quantitative analyses were made on the diurnal variation in extinction coefficient of canopy direct radiation with different plant types,the vertical distribution characteristics of direct radiation at noon and of photosynthetic rate within canopy,the characteristics of canopy photosynthetic rate with the changed leaf area index (LAI) under different radiant intensities,as well as the diurnal variation of canopy photosynthetic rate under different radiant intensities.The results showed that the high yield potential of compact plant type in rice relied on higher LAI,leaf photosynthetic efficiency,solar altitude and the intensity of solar radiation.These results would provide a support on cultivation for high yield and optimal design of plant type in rice crop.
