水稻叶龄模型在形态建成模拟中的应用

阐述了叶龄模型在水稻形态建成模拟中的应用,结果表明,用叶龄模型预测水稻播种至抽穗期的生育进程,与观察值吻合较好,根据叶龄与根,蘖,穗等器官的同伸关系,用叶龄模型预测各器官的发育进程,可用以编制水稻生长日历,预测当年水稻生长发育进程和器官形成进程,为高产栽培的调控决策提供指导。

APPLICATION OF THE LEAF-AGE MODEL IN THE SIMULATION OF RICE MORPHOGENESIS

This paper with the application of the rice leaf-age model in rice morphogenesissimulation,The results showed that the simulated values of the growth-gevelopment process-es from sowing to heading agreed well with the measured values from the field experiments.According to the synchronous relation between the rice leaf-age and the morphogenesis in-cluding the root,stem,tiller and panicle,the prediction of the growth-development of organsby using the leaf-age model can be used in establishing the"Rice Growth Calendar",TheseresuIts will provide guide for regulation of rice-growth.
