| 摘 要： | 在水稻株型设计系统(Rice Plant Type Design System,RPTDS)基础上,以冠层光分布为指标,利用改造后的非自然群体,通过田间实验和虚拟实验的比较研究,对RPTDS系统中水稻冠层三维模型的准确性进行了检验,结果表明,虚拟实验结果与田间实验结果虽然在数值上存在一定差异,但具有极显著的正向相关关系,同时,虚拟实验结果更能够有效反映冠层结构差异,冠层模型具有较高的准确性。说明RPTDS系统基本能够准确反映群体冠层结构和光分布态势。

| Abstract: | On the basis of Rice Plant Type Design System(RPTDS),using modified rice population,light distribution was investigated.By the comparison with the result of field experiment,the veracity of the 3-dimentional model of rice canopy was checked.The result shows that there is a significant positive correlation exists despite the numerical difference.The data of the virtual experiment could reflect the differences of canopies and shows high veracity. It indicates that RPTDS could reflect rice canopy structure and its light distribution effectively. |
