不同株型水稻叶倾角群体分布的模拟
Simulation of Leaf Inclination Angle Distribution for Rice with Different Plant Types
摘要
Abstract
A model for simulating leaf inclination angle distribution was established by the plant type factors of three plant types,and validated by the present experiment. The coefficient of determination (R2) and the root mean square error (RMSE)between the simulated and measured values are 0. 9472 and 3. 93% , respectively. The simulation results of the model showed that there was different distribution of leaf inclination angle in the three plant types. The leaf inclination angle of compact plant type, Liangyoupeijiu (erect leaves) is larger than a loose plant type, Shanyou 63 (droopy leaves) and intermediate type, Liangyou Y06. Shanyou 63 showed the lowest inclination angle of leaf which is consistent with the observation. For a variety, there was also different leaf inclination angle distribution at the seven growth stages. Canopy leaf inclination angle became larger and larger from transplanting to booting stage. After booting, with the advance of growing, leaf inclination angle of Shanyou 63 and Liangyou Y06 was getting larger, while Liangyoupeijiu showed little change. Canopy leaf inclination angle distribution at six heights showed different for a material at a growth stage. With the increase of canopy height, layered leaf area index decreased in the three plant types, and the leaf inclination angle of Liangyoupeijiu showed little change. However, with the increase of canopy height, leaf inclination angle was getting larger for Shanyou 63, and much smaller for Liangyou Y06. The present model proved that simulation results of the model come very close to the actual values.关键词
