Abstract: By using three rice hybrids with  typical plant types as  materials, and changing their morphology of uppermost two leaves through  N fertilizer application   during the elongation of   the two leaves, relationships among plant type factor, layered leaf area and radiation transmission were determined at the full heading stage, 10 and 25 days after full heading, respectively. A model for calculating  the layered leaf area by plant type factors was established and validated, and were subjected to analyze  the effects of plant type factors on layered leaf area of  the three hybrids. Furthermore,    the relationship between layered leaf area and radiation transmission was validated using a light distribution model for plant canopy radiation transmission, and the effects of plant type factors on radiation transmission for the three hybrids were conducted  by  this  model. Thus,  a method for calculating canopy structure (layered leaf area index) and radiation transmission  was established by plant type factors in rice.

摘要: 以3个具有代表性株型的杂交稻为材料,并结合上位2叶伸长期施用氮肥以调节上部叶片的形态,于齐穗期、齐穗后10 d、齐穗后25 d平行测定了株型元素分层叶面积冠层光分布。用试验数据验证了由水稻株型因子计算分层叶面积的解析模型,并用该模型分析了3个材料株型因子对冠层结构的影响。进一步根据作物群体光分布模型,验证了分层叶面积与冠层内光分布的数值关系,并用该模型分析了3个材料株型因子对冠层内辐射分布的影响。实现了由水稻株型因子估算冠层结构和冠层内光分布的方法。
