摘要
根据水稻器官生长的生物学规律,在试验研究的基础上,结合生长模型相关输出,构建了普适性的水稻冠层拓扑结构模型。以节间及其着生叶或穗为单位,将水稻植株分解成若干生长单元,来描述水稻植株的冠层拓扑结构;利用Logistic曲线模拟器官伸长过程,并结合器官发育与叶龄关系,确定了各器官的初始伸长时间和伸长历期,构建了水稻植株冠层动态生长模型;最后对模型进行了检验,初步实现了以日为单位的虚拟水稻生长。
Simulating crop growth visually on computer can help to better understand crop growth pattern and analyze the relationship between architecture and function.Some architecture models were developed to simulate development of crops in a given time interval,such as leaf age and growth unit.Most of them didn t discuss the organ elongation processes and daily architecture change.So in order to realize more accurate and delicate crop growth,it is important to develop more applicable models to describe the dynamic...
