To do so, an FSPM of rice seedling was developed in this study, including structural morphogenetic model, photosynthetic model and biomass partitioning module. It can thus describe the developmental course of the rice structure dynamically based on the processes of biomass producing and partitioning. Furthermore, the processes of nitrogen metabolism, which influence the N content and growth dynamics of the virtual rice, were also considered. The model was developed with L-system on a platform established with Java programming language, which took over the parsing and visualization of the L-system strings to 3D objects using Java 3D extended library. The physiological processes in the model can be modified and further improved to gradually meet the needs for modeling the whole life cycle of rice, e.g., considering the respiration, and interaction with other environmental factors like CO2, temperature, etc.. The model was developed to provide a platform to systematically study and understand how plant systems like rice seedling work. The model and the virtualization platform can be expanded to provide decision support on N fertilizer application for the rice seedling and the other crops.展开更多

The results show that the mulberry fiber is cellulose fiber. The crystal structure of mulberry fiber is cellulose I and the crystal cell belongs to the monoelinic system. The mulberry fiber crystal degree is 62.9% and orientation degree is 43.7%, the fineness of mulberry fiber is 2.3- 3.9 dtex, the length of the single fiber is 28 - 47 mm, the breaking strength of mulberry fiber is about 2.93 cN/dtex, and the initial modulus is about 76.82 cN/dtex.展开更多
