以超高产杂交稻两优培九为材料,于2006年和2007年在江苏扬州、福建尤溪、湖北武汉、云南涛源、四川江油、广东广州、海南海口、广西南宁共8个生态试验点进行齐穗期株型观测,分析了各个生态点株型特征,并根据相应气象资料建立了两优培九齐穗期株型的环境模型.依据1951-2005年的气候资料模拟,比较了华南双季稻区、长江中下游稻区、四川盆地稻区和云南河谷单季籼稻区齐穗期两优培九株型的特征与差异,分析了4个稻区叶片形态差异对植冠层结构的影响.提出植冠层有效厚度和叶面积密度可以作为水稻"株型产量"载体的2个群体结构指标.

By using a two-line hybrid rice combination, Liangyoupeijiu, several factors of plant type were estimated and environmental models for such factors at the heading stage were established with the data of eight ecological experimental sites in 2006 and 2007. According to the climatic data from 1951 to 2005, differences in such factors and their effects on plant canopy were analyzed for four rice cropping areas, including South China, the middle-lower reaches of the Changjiang River, Sichuan Basin, and river valley in Yunnan, China. The thickness of leaf layer(the distance from pulvinus of the third leaf from the top to the tip of flag leaf) and distribution of leaf area can be used as candidate index for plant type of a rice canopy.
