中文摘要:本文在1983年试验研究的基础上,进一步探讨了水稻生长与产量形成的数值模拟方法。对1983年试验建立的水稻叶、茎、根、穗等器官生长模式用梯形近似法求解得出描述水稻生长和产量形成过程的递推表达式;对水稻群体同化能力、同化物分配转移规律也进行了初步研究;并用最优化方法确定出模式参数的最优解,模拟了1984年水稻生长发育和产量形成过程。
 
AN EXPERIMENT ON NUMERICAL SIMULATION OF RICE YIELD PREDICTION
Abstract:The present work is the continuation of the experiment inaugurated in 1983. The model constructed in 1983 for the growth of various organs of the rice plant is solved by means of the trapezoidal method, resulting in a recurrence formula which described the processes of rice growth and yield formation. Preliminary investigation is also made on the assimilative ability, the assimilator distribution and the transition of the rice population. Optimal solutions of the model parameters are determined through optimization. Also simulated are the processes of rice growth and yield formation in 1984.
